Xerosis is highly prevalent in the population aged over 50 years and substantially impacts quality of life due to the associated stigma, related pruritus, and potential sequelae. We propose that the term mature xerosis be used for subjects over 50 who suffer from age‐related xerosis and replace senile xerosis to describe the phenomenon. The etiology of xerosis depends on genetic and environmental factors that affect stratum corneum hydration and skin barrier function. Skincare to restore barrier function is essential in xerosis treatment and is relevant for maintaining and preventing its progression. Many moisturizers and cleansers are available for xerosis; however, they are underutilized by patients with mature xerosis. A panel of eight global dermatologists reviewed the unique aspects of xerosis in mature skin and discussed the specific needs, relevance, and considerations for skincare selection to prevent, treat, and maintain skin with mature xerosis. The panel selected five statements based on evidence from a literature review and the panel's clinical experience to provide clinical considerations and recommendations for dermatologists and other healthcare providers treating patients with mature xerosis. Increased recognition of the burden of xerosis in mature skin is warranted. Gentle cleansers and barrier‐restoring ceramide‐containing moisturizers are essential to xerosis management, reducing signs and symptoms of xerosis, including associated pruritus.

Microbial dysbiosis is increasingly understood to influence allergic sensitization and skin barrier defects in dermatitis. Occlusion, such as from moisturizers, fosters microbial dysbiosis, and increases itch in many patients with dermatitis. Nevertheless, use of moisturizers in dermatitis remains part of dermatologic guidelines. This is a review of the evidence of benefits and adverse effects of moisturizers in dermatitis and a proposal for moderation in their clinical use. [ABSTRACT FROM AUTHOR]

ABSTRACT Background Objective Methods Results Conclusion Moisturizers are a crucial baseline therapy for atopic dermatitis (AD).To evaluate the real‐life experience of using moisturizers in AD patients and to assess parents' opinions and challenges regarding moisturizer use.This cross‐sectional study used a questionnaire completed by the parents of pediatric AD patients. The assessment questionnaire evaluated demographic factors as well as practices, opinions, and challenges regarding the use of moisturizers in AD treatment. Applying moisturizers twice daily, considered sufficient use, was evaluated across demographic levels using bivariate analysis.A total of 425 patients with AD participated in the study. The median age was 4 years, 51% of patients were female, 61% had moderate to severe AD, 34% had a family history of AD, and 41% of cases reported sufficient moisturizer use. Factors associated with increased frequency of application of moisturizers included younger age at diagnosis, higher parents' educational level, and increased family income. The twice‐daily application versus less frequent application was associated with fewer monthly flare‐ups (33% vs. 17%, p < 0.001). Overall, 54% of patient guardians believed that moisturizers were necessary for treating AD, 69% considered fragrance‐free formulas to be better, and 86% thought there to be a need for counseling from their physician on using moisturizers in AD treatment. Factors undermining the application of moisturizers included the time needed for application, cost, and lack of patient cooperation.In real‐world practice, parents tend to underutilize moisturizers. To address this issue, treating physicians must provide additional education, and health insurance companies should consider covering moisturizers to ensure their accessibility.

\nIntroduction: So far, no definitive conclusions have been reached regarding the preventive effect of moisturizers on atopic dermatitis (AD). The variability in results may be due to differences in skin care methods, including bathing and washing, among studies and study design. In hot and humid Japan, bathing and gauze washing have been routinely practiced from the neonatal period, but this may impair the skin barrier function. To address this gap, we determined whether a combination of minimally invasive cleaning methods and moisturizing may prevent AD in infants in Japan. Methods: Mothers of children born between January and September 2019 were instructed in traditional skin care methods (control group; 132 subjects), and mothers of children born between January and September 2020 were instructed in a new skin care method combining less invasive washing and moisturizing (intervention group; 140 subjects). Mothers and babies with and without a history of allergy were recruited, and the incidence of AD at 1 year of age was investigated by questionnaire. Results: Skin care-related behaviors such as face washing, hand washing, and use of moisturizers were more frequent in the intervention group than in the control group. At 6 and 12 months of age, there was no difference in the incidence of AD between the two groups. However, for children born between January and March, the prevalence of AD at 12 months was significantly lower in the intervention group than in the control group (2.9% vs. 21.2%, p = 0.0253). Conclusions: This study suggests that for children born during dry and cold seasons, strengthening the skin barrier function early in life through routine skin care with less invasive washing and moisturizing may prevent AD in Japan. Appropriate skin care practices for newborns and infants may vary in regions and environments. Impaired skin barrier function is one of the main causes of atopic dermatitis (AD). European guidelines recommend reducing the frequency of bathing so as not to impair the skin barrier function. In addition, to date, many studies have attempted to prevent AD by using moisturizers starting in infancy, with conflicting results. The variation in these results may be due to differences in skin care methods such as washing and moisturizing. In Japan, frequent bathing and gauze washing are commonly used from the neonatal period. The purpose of this study was to determine whether a combination of less invasive washing methods and moisturizing could prevent AD in infants. Mothers of infants born between January and September 2019 were instructed in conventional skin care methods (control group; 132 subjects), and mothers of infants born between January and September 2020 were instructed in a new, less invasive skin care regimen combining washing and moisturizing (intervention group; 140 mothers). Mother/infant dyads with and without a history of allergies were recruited and the incidence of AD at 1 year of age was investigated. The prevalence of AD at 12 months was significantly lower in the intervention group than in the control group for infants born between January and March (2.9% vs. 21.2%). This study suggests that for children born during the dry, cold season, strengthening the skin barrier function early in life with less invasive cleaning and moisturizing skin care may prevent AD.

Dermatoporosis is a chronic skin insufficiency syndrome with typical manifestations of extreme skin atrophy, senile purpura, stellate pseudoscars, skin lacerations, and skin dissecting hematomas at the age of 70–90 years old. It is caused by aging process, and triggered by environmental factors and drugs which lead to the skin's protective mechanical function loss. The prevalence was 32% in French Hospitals and 30.7% in the Central Hospital of the University of Helsinki, Finland. We report a dermatoporosis case to raise awareness in clinical practice and trace study literature for choosing the most appropriate therapy. An 89-year-old man complained of red and itchy patches on his skin since the last six months. Physical examination shows dry skin, atrophy, purpura, stellate pseudoscars, and multiple arms and lower leg lacerations. The patient had been given ceramide moisturizer, but there is no significant improvement. Structural and functional skin damage in elderly is not just cosmetic problem. However, it significantly impacts life quality and increases morbidity and mortality risk if it develops into a serious condition. Therefore, clinicians have an essential role in proper management to prevent complications. Several studies have shown that hyaluronic acid and retinaldehyde improve skin function in dermatoporosis.

This review provides an overview of the structural and functional features of key phytosphingosine-based ceramides (CERs), notably CER[EOP], CER[NP], and CER[AP], and their role in atopic skin health. Herein, we discuss how these indispensable stratum corneum (SC) lipids maintain skin barrier homeostasis and contribute to the skin’s barrier function in terms of its cohesiveness and resilience. We also consider the usefulness of CER[EOP], CER[NP], and CER[AP] in preserving skin hydration and protecting and/or repairing dry, itchy, or sensitive skin. Next, we explore how and to what extent an imbalance or inadequate amounts of CER[EOP], CER[NP], and CER[AP] contribute to the hallmark characteristics of atopic skin diseases like eczema. Furthermore, we discuss the importance of complementary SC resident lipids such as cholesterol (CHOL) and free fatty acids (FFAs), which are crucial for optimal CER function. Studies have shown that delivering topical CERs in balanced and optimal combination with CHOL and FFAs—while supporting and boosting the endogenous biosynthesis of CERs using ingredients such as niacinamide and lactic acid—helps relieve symptoms of atopic diseases to provide some measure of relief. Finally, we look at some emerging ingredients that can complement the science of CERs in healthy and diseased skin.

Moisturizers are cosmetic compounds designed to increase the moisture content of the skin. There are many types of these products in the market making it difficult for consumers to select the most effective moisturizer according to their age and gender. Hence, the aim of this study was to evaluate the effects of different moisturizers on skin hydration as well as to figure out any dependencies of the effects of these products on age or gender-related differences. We investigated the short-term moisturizing effects of five different skin moisturizers on 60 participants by using a low frequency electrical instrument. Skin surface susceptance was recorded and compared before and after the application of moisturizers. Statistically significant differences were observed in the moisturizing effect among different types of products. However, with respect to gender and age differences, there were insignificant differences in the effects of the moisturizers. Results of this study suggest that some types of moisturizers that exist in the markets are not as effective as required, which calls for a further evaluation of the moisturizers before entering markets and offering them for sale. In addition, findings suggest that gender or age differences are perhaps not important to consider in the application of moisturizers.

BACKGROUND: Hyaluronic acid (HA) is a unique molecule of the extracellular matrix with multiple biological activities. In skin, HA plays an essential role as a humectant, capable of binding up to 1,000 times its mass with water, providing skin with moisture and viscoelastic properties. HA concentration and synthesis decrease significantly in aging skin, due to exogenous and endogenous factors, including photoaging and HA metabolism. A key driver for HA degradation and reduced concentration is mediated via induction of reactive oxygen species (ROS) and other free radicals. OBJECTIVE: In this study, we evaluate antioxidant ingredients essential in the development of next-generation HA-based topical formulations aimed at leveraging HA's ability to maximize anti-aging properties. METHODS: Two antioxidants, glycine saponin (Glycine soja germ extract) and glycyrrhetinic acid (enoxolone), were evaluated for stimulation of endogenous HA production and inhibition of endogenous hyaluronidase activity, respectively. RESULTS: The antioxidant glycine saponin induced endogenous HA synthesis in fibroblasts, while the antioxidant glycyrrhetinic acid decreased the degradation rate of HA by 54 percent. CONCLUSION: While HA has been included in numerous topical skin products, critical aspects of HA metabolism, especially in aging skin, have often been overlooked, including decreases in HA synthesis with increasing age, and increases in HA degradation mediated by exogenously induced reactive oxygen species and free radicals and increased enzymatic degradation by endogenous hyaluronidases. Here, we describe a unique approach to inclusion of two antioxidants essential for the development of the next generation of antioxidant complex-based topical skin formulations to limit the signs of aging skin.

Potatoes are one of the food crops that most widely consumed as a source of energy. Processed potato foods vary greatly, one of which is fried potato sambal. The aim of this Community Service (PkM) is to provide product innovation to business owners so that they can increase the income of the owner of the fried potato sambal business. The place where this community service is carried out is at the Fried Potato Sambal Production House in Geuceu Menara Village, Jaya Baru Subdistrict, Banda Aceh. This production house usually uses red potatoes as the main raw material. In this PkM activities, potato skins, which are usually waste, will be innovated into moisturizing products for the skin. There are two types of potatoes used in this PkM activities, namely yellow potatoes and red potatoes. Both of the potatoes were peeled, those peel were extracted and then these two extracts will be used as the main ingredients in making moisturizer products. Antioxidant activity was also determined using the DPPH method. The results obtained were that the extracts of both types of potato skin had antioxidant activity with IC50 values of 5.10 (yellow potato skin) and 11.32 (red potato skin). In conclusion, yellow potato skin extract and red potato skin extract have strong antioxidant activity so that they can be used as a good moisturizer product.

Atopic dermatitis is a prevalent chronic skin condition affecting over 10 % of the pediatric population, with its pathogenesis rooted in immunological factors. Despite the advancements in understanding its triggers and pathophysiology, the frequency of AD remains high, necessitating a multidisciplinary approach for effective management. This article discusses therapeutic strategies, emphasizing the collaboration between pediatric dermatologists and allergists, along with the potential role of psychologists for addressing the psychosocial impact. The severity of AD is assessed using validated clinical scores, such as SCORAD and EASI, guiding treatment decisions. The article provides a detailed overview of acute phase management for mild cases, highlighting the importance of topical corticosteroids based on potency and absorption considerations. Additionally, it explores the use of topical calcineurin inhibitors in sensitive areas. For moderate cases with relapses, proactive therapy and considerations for bacterial over-infection are discussed. Lately there has been a shift from immunosuppressants to biologic drugs like dupilumab for severe forms, demonstrating efficacy even in pediatric cases. The article outlines approved dosing for dupilumab across different age groups. In the remission phase, environmental measures and psychological support are crucial, while emollient therapy, categorized by occlusive, humectant, and emollient actions, remains a cornerstone. Furthermore, the incorporation of non-medicated active ingredients in emollients is explored. The multidisciplinary approach and stepwise therapeutic strategies outlined in this article aim to assist clinicians in managing AD cases effectively based on clinical severity, ensuring optimal outcomes for pediatric patients.

Skin is the part of the outer body that is most often exposed to external factors, especially ultraviolet radiation. The skin has an important role in supporting the appearance so that it can affect human social life. Skin aging is a process of decreasing the body's physiological functions that cannot be avoided. The aging process of the skin can be caused by a decrease in collagen density and replacement of essential structural proteins so that the skin loses its integrity and elasticity. Collagen is the most abundant protein in humans which can be found in bones, muscles, skin and tendons. Several studies have shown that damaged collagen fibers can be replaced by new fibers when collagen production is stimulated, which is why many cosmetic industries are competing to develop the use of collagen. Collagen has shown potential as an antioxidant, skin moisturizer, and anti-aging. Therefore, this article examines the benefits of collagen, especially in the cosmetic field. This article also discusses the sources of collagen with the best properties as active ingredients for skin care products. [ABSTRACT FROM AUTHOR]

Introduction: Acne is a common, complex, multifactorial inflammatory skin disease associated with epidermal barrier dysfunction. Beginning in childhood, acne affects many adolescents and adults. Acne is associated with lower self‐esteem, anxiety, and depression and may cause scars and pigmentary sequelae. The review explores the relationships between acne and the skin barrier function and discusses nuances in the prevention, treatment, and maintenance of acne and its impact on the skin barrier. Methods: The advisors' previous publications addressed prescription and nonprescription pediatric acne treatment and skincare using cleansers, moisturizers, and a practical algorithm for treatment and maintenance, including skincare recommendations for pediatric acne patients and an algorithm for skin of color patients with acne. Before the meeting, literature was culled on the relationship between the skin barrier and acne and current best practices in acne, addressing prescription and nonprescription acne products and skincare as monotherapy, adjunctive, and maintenance treatment. Results: After discussing 13 draft statements, the advisors applied the selected literature and drew from their clinical knowledge and experience, and agreed on five statements. The follicular epithelial barrier is directly involved with changes that occur during both comedogenesis and in stages of inflammation, especially with follicular rupture compromising the barrier's integrity. In acne‐affected skin, sebaceous glands are larger, sebum excretion and filaggrin expression higher, and stratum corneum lipids are reduced. Educating patients and clinicians about inflammation's central role in acne and measures to reduce inflammation is essential. Skin irritation and xerosis from acne and treatments lead to poor treatment adherence. A skincare regimen should be included in the acne prevention, treatment, and maintenance care regimen and should be ongoing. Maintenance treatment with topical agents and skincare using gentle ceramide‐containing cleansers and moisturizers is a recommended strategy after successfully controlling the disease. Conclusions: Epidermal barrier dysfunction contributes to acne exacerbation. Using the appropriate treatment and skincare helps to minimize irritation and inflammation, enhance treatment adherence, and improve patient outcomes. [ABSTRACT FROM AUTHOR]

Non-invasive scar management typically involves pressure therapy, hydration with silicones or moisturizers, and UV protection. Moisture loss from scars can lead to hypertrophic scar formation. Pressure therapy reduces blood flow, fibroblast activity, and transforming growth factor beta 1 (TGF-β1) release. This study examined various moisturizers and liquid silicone gel's impact on microcirculation. 40 volunteers participated in a study where superficial abrasions were created to induce trans epidermal water loss (TEWL). Five moisturizers (TEDRA®, TEDRA® NT1, TEDRA® NT3, Alhydran®, Lipikar®) and BAP Scar Care® silicone gel were tested. TEWL, hydration, and blood flow were measured up to 4 h post-application. Results showed that silicone had the least impact on occlusion and hydration. Alhydran® reduced blood flow the most, while Lipikar® increased it the most. TEDRA® NT1 had reduced flow compared to TEDRA® and TEDRA® NT3. All TEDRA® products exhibited high hydration, and all but silicone showed good occlusion. Moisturizers influenced skin microcirculation, with some causing decrease, while others increased flow. However, the clinical impact on scarring remains unclear compared to the evident effects of hydration and occlusion. More research is necessary to study moisturizers alone and with pressure therapy on scars, along with potential adverse effects of increased microcirculation on scars. [ABSTRACT FROM AUTHOR]

Abstract In Japan, as in other countries around the world, acne vulgaris is a common disease and a frequent reason for patients to consult dermatologists. For optimal management of acne, it is important to understand how available products to support skin health can be used both with and without prescription products. Dermocosmetics can be defined as skincare agents with dermatologically active ingredients that directly support or care for the symptoms of various skin conditions (distinct from vehicle effects). There are products with active ingredients—including familiar ones such as niacinamide, retinol derivatives, and salicylic acid—that target important aspects of acne pathophysiology. Others, including ceramides, glyercin, thermal spring water, and panthenols, may have positive effects on skin barrier function that are useful in managing acne. This publication will discuss the roles of dermocosmetics in acne either as monotherapy to manage the milder forms of acne and help prevent relapses, or as adjuncts to prescription therapy to increase efficacy or adherence and assist in prevention of local adverse effects. Dermocosmetics may also have active ingredients that positively impact the skin microbiome.

Background: Moisturizers are first‐line therapy for treatment of atopic dermatitis (AD). Although there are multiple types of moisturizers available, head‐to‐head trials between different moisturizers are limited. Objective: To evaluate if a paraffin‐based moisturizer is as effective as ceramide‐based moisturizer in children with AD. Materials and Methods: In this double‐blind, randomized comparative trial of pediatric patients with mild to moderate AD, subjects applied either a paraffin‐based or ceramide‐based moisturizer twice daily. Clinical disease activity using SCOring Atopic Dermatitis (SCORAD), quality of life using Children/Infants Dermatology Life Quality Index (CDLQI/IDLQI), and transepidermal water loss (TEWL) were measured at baseline and at follow‐up at 1, 3, and 6 months. Results: Fifty‐three patients were recruited (27 ceramide group and 26 paraffin group) with a mean age of 8.2 years and mean disease duration of 60 months. The mean change in SCORAD at 3 months in the ceramide‐based and paraffin‐based moisturizer groups was 22.1 and 21.4, respectively (p =.37). The change in CDLQI/IDLQI, TEWL over forearm and back, amount and days of topical corticosteroid required, median time to remission and disease‐free days at 3 months were similar in both groups. As the 95% confidence interval (CI) of mean change in SCORAD at 3 months in both groups (0.78, 95% CI: −7.21 to 7.52) was not within the predefined margin of equivalence (−4 to +4), the conclusion of equivalence could not be proven. Conclusion: Both the paraffin‐based and ceramide‐based moisturizers were comparable in improving the disease activity in children with mild to moderate AD. [ABSTRACT FROM AUTHOR]

Background: The anatomic layers of the skin are well-defined, and a functional model of the skin barrier has recently been described. Barrier disruption plays a key role in several skin conditions, and moisturization is recommended as an initial treatment in conditions such as atopic dermatitis. This review aimed to analyze the skin barrier in the context of the function model, with a focus on the mechanisms by which moisturizers support each of the functional layers of the skin barrier to promote homeostasis and repair. Summary: The skin barrier is comprised of four interdependent layers – physical, chemical, microbiologic, and immunologic – which maintain barrier structure and function. Moisturizers target disruption affecting each of these four layers through several mechanisms and were shown to improve transepidermal water loss in several studies. Occlusives, humectants, and emollients occlude the surface of the stratum corneum (SC), draw water from the dermis into the epidermis, and assimilate into the SC, respectively, in order to strengthen the physical skin barrier. Acidic moisturizers bolster the chemical skin barrier by supporting optimal enzymatic function, increasing ceramide production, and facilitating ideal conditions for commensal microorganisms. Regular moisturization may strengthen the immunologic skin barrier by reducing permeability and subsequent allergen penetration and sensitization. Key Messages: The physical, chemical, microbiologic, and immunologic layers of the skin barrier are each uniquely impacted in states of skin barrier disruption. Moisturizers target each of the layers of the skin barrier to maintain homeostasis and facilitate repair. [ABSTRACT FROM AUTHOR]

Banana is one of the common fruits in Indonesia that can be processed into other products, such as Sale Banana which is one of the typical souvenirs from Aceh. The purpose of this community service activity (PkM) is to increase the income of business owners and Sale Banana traders. The community service location is dedicated to small and medium enterprises in Alue Naga Village, Banda Aceh. Through this PkM activities, Sale Banana is used to create a new product that is a moisturizing product for the skin. Two types of bananas are used in this PkM, namely Awak banana and Kepok banana. The extracts of the two bananas are used as the main ingredient of the moisturizer. The antioxidant activity of the two banana extracts was tested using the DPPH method. Based on the results of community service, skin moisturizers have an IC50 antioxidant activity of 10.52 (Kepok banana) and 14.00 (Awak banana). It could be concluded that both Sale Kepok Banana extract and Awak Banana extract have a strong antioxidant activity and could be used as a good moisturizer.

Abstract The global cosmetics market reached US$500 billion in 2017 and is expected to exceed US$800 billion by 2023, at around a 7% annual growth rate. The cosmetics industry is emerging as one of the fastest-growing industries of the past decade. Data shows that the Chinese cosmetics market was US$60 billion in 2021. It is expected to be the world's number one consumer cosmetics market by 2050, with a size of approximately US$450 billion. The influence of social media and the internet has raised awareness of the risks associated with the usage of many chemicals in cosmetics and the health benefits of natural products derived from plants and other natural resources. As a result, the cosmetic industry is now paying more attention to natural products. The present review focus on the possible applications of natural products from various biological sources in skin care cosmetics, including topical care products, fragrances, moisturizers, UV protective, and anti-wrinkle products. In addition, the mechanisms of targets for evaluation of active ingredients in cosmetics and the possible benefits of these bioactive compounds in rejuvenation and health, and their potential role in cosmetics are also discussed.

Introduction: Dry skin is a hallmark of impaired skin barrier function. Moisturizers are a mainstay of treatment to help the skin retain moisture, and there is a high consumer demand for effective products. However, the development and optimization of new formulations are hampered due to lack of reliable efficacy measures using in vitro models. Methods: In this study, a microscopy-based barrier functional assay was developed using an in vitro skin model of chemically induced barrier damage to evaluate the occlusive activity of moisturizers. Results: The assay was validated by demonstrating the different effects on barrier function between humectant (glycerol) and occlusive (petrolatum). Significant changes in barrier function were observed upon tissue disruption, which was ameliorated by commercial moisturizing products. Conclusion: This newly developed experimental method may be helpful to develop new and improved occlusive moisturizers for the treatment of dry skin conditions. [ABSTRACT FROM AUTHOR]

Chronic kidney disease‐associated pruritus (CKD‐aP) is a common and distressing symptom for patients with CKD and a difficult challenge for nephrologists and dermatologists. Recent results showed the multifactorial nature of the pathophysiology, and therapeutic trials were only successful in certain subsets of patients. The clinical manifestations are varied, with xerosis being the most common dermatological manifestation and correlated with the intensity of CKD‐aP. A better understanding of the pathophysiology of xerosis in CKD‐aP and appropriate topical treatment could correct xerosis to reduce the intensity of CKD‐aP and improve the patient's quality of life.

Food allergy represents a growing public health and socio-economic problem with an increasing prevalence over the last two decades. Despite its substantial impact on the quality of life, current treatment options for food allergy are limited to strict allergen avoidance and emergency management, creating an urgent need for effective preventive strategies. Advances in the understanding of the food allergy pathogenesis allow to develop more precise approaches targeting specific pathophysiological pathways. Recently, the skin has become an important target for food allergy prevention strategies, as it has been hypothesized that allergen exposure through the impaired skin barrier might induce an immune response resulting in subsequent development of food allergy. This review aims to discuss current evidence supporting this complex interplay between the skin barrier dysfunction and food allergy by highlighting the crucial role of epicutaneous sensitization in the causality pathway leading to food allergen sensitization and progression to clinical food allergy. We also summarize recently studied prophylactic and therapeutic interventions targeting the skin barrier repair as an emerging food allergy prevention strategy and discuss current evidence controversies and future challenges. Further studies are needed before these promising strategies can be routinely implemented as prevention advice for the general population. [ABSTRACT FROM AUTHOR]

Background: Treatment, cleansing, moisturizing, and photoprotection are four major components of holistic skin care for dermatological conditions. While treatment (T) is recognized as a key component in the management of dermatological conditions, there is a lack of practical guidance on the adjunctive role of cleansing, moisturizing, and photoprotection ("CMP"). Limited patient knowledge, confusion over product selection, and lack of guidance on how to choose and use CMP skin care products (in conjunction with pharmacological therapy) are the main barriers to establishing a holistic skin care routine for dermatological conditions. Aims: This study aimed to review current clinical evidence, identify gaps, and provide practical guidance on conceptualization and implementation of CMP routine in the management of sensitive skin due to underlying acne, atopic dermatitis, or rosacea, including conditions with idiopathic causes referred to as idiopathic sensitive skin syndrome. Methods: An expert panel comprising of 10 dermatologists from Australia, China, Hong Kong, Taiwan, India, Indonesia, Philippines, Singapore, South Korea, and Thailand convened to develop consensus statements on holistic skin care in acne, rosacea, atopic dermatitis, and idiopathic sensitive skin syndrome using the Delphi approach. Results: Consensus was defined as ≥80% of panel rating statement as ≥8 or median rating of ≥8. The final statements were collated to develop consensus recommendations on holistic skin care. Conclusion: A dermatologist‐guided holistic skin care routine is essential to improve patient confidence and reduce confusion over product selection. The consensus recommendations presented here highlight the importance of cleansing, moisturization, and photoprotection in holistic skin care and how it can be utilized as a communication tool for physicians and patients to achieve overall better patient compliance, satisfaction, and treatment outcomes.

Objective: To decode the feeling of skin tightness after application of a cosmetic product and how to soothe this discomfort. To pursue this aim, we considered the ingredient's effect on stratum corneum (SC) biomechanics to differentiate between consumers prone to tightness from those that are not and correlate these effects with mechanoreceptor activation. Methods: In vivo clinical trials were used to assess the tightness perception dichotomy between groups of Caucasian women; in vitro experiments were used to measure the mechanical stresses induced in the SC after cleanser and moisturizer application; and in silico simulations were used to illustrate how the measured mechanical stresses in the SC result in the development of strains at the depth of cutaneous mechanoreceptors, triggering tightness perceptual responses. Results: Before any cream application, women prone to tightness tend to have a more rigid SC than their less sensitive counterparts, however cleanser application increases SC stiffness in all women. Surprisingly, no correlation was found between tightness perception and hydration measurements by the Corneometer or barrier function, as evaluated by transepidermal water loss. Self‐declared tightness and dryness scores were strongly associated with a self‐described sensitive skin. After application of the optimized moisturizing formula, Osmoskin® containing natural waxes with good filming properties, consumers report a strong decrease in tightness and dryness perception. These results match with laboratory experiments where the cleanser was shown to increase SC drying stresses by 34%, while subsequent application of Osmoskin® decreased stresses by 48%. Finite element modelling, using experimental results as input, elucidates the differences in perception between the two groups of women. It makes clear that Osmoskin® changes the mechanical status of the SC, producing strains in underlying epidermis that activates multiple cutaneous mechano‐receptors at a level correlated with the self‐perceived comfort. Conclusion: Integration of the in vivo, in vitro and in silico approaches provides a novel framework for fully understanding how skin tightness sensations form and propagate, and how these sensations can be alleviated through the design of an optimized moisturizer.

Atopic dermatitis, the most common form of eczema, is a chronic, relapsing inflammatory skin condition that occurs with dry skin, persistent itching, and scaly lesions. This debilitating condition significantly compromises the patient's quality of life due to the intractable itching and other associated factors such as disfigurement, sleeping disturbances, and social stigmatization from the visible lesions. The treatment mainstay of atopic dermatitis involves applying topical glucocorticosteroids and calcineurin inhibitors, combined with regular use of moisturizers. However, conventional treatments possess a certain degree of adverse effects, which raised concerns among the patients resulting in non-adherence to treatment. Hence, the modern use of moisturizers to improve barrier repair and function is of great value. One of the approaches includes incorporating bioactive ingredients with clinically proven therapeutic benefits into dermocosmetics emollient. The current evidence suggests that these dermocosmetics emollients aid in the improvement of the skin barrier and alleviate inflammation, pruritus and xerosis. We carried out a critical and comprehensive narrative review of the literature. Studies and trials focusing on moisturizers that include phytochemicals, natural moisturizing factors, essential fatty acids, endocannabinoids, and antioxidants were identified by searching electronic databases (PubMed and MEDLINE). We introduce the current knowledge on the roles of moisturizers in alleviating symptoms of atopic dermatitis. We then further summarize the science and rationale of the active ingredients in dermocosmetics and medical device emollients for treating atopic dermatitis. Finally, we highlight the limitations of the current evidence and future perspectives of cosmeceutical research on atopic dermatitis. [ABSTRACT FROM AUTHOR]

Moisturizers are one of the most widely used preparations in cosmetics and have been extensively used to soften the skin for consumers. Moisturizers work effectively in combating dry skin which may cause pain, tightness, itch, stinging, and/or tingling. The aim of this review is to evaluate published studies on the history, ingredients, preparation processes, characteristics, uses, and applications of moisturizers. Moisturizers bridge the gap between medicine and consumer goods by being used to make the skin more beautiful and healthy. In the future, in moisturizer therapy, the capacity to adapt specific agents to specific dermatological demands will be crucial. Cosmetically, moisturizers make the skin smooth by the mechanism of increasing the water content in the stratum corneum, hence exerting its most vital action, which is moisturizing action and maintaining a normal skin pH.

Background: Pediatric atopic dermatitis(AD) is very common, but its management is frustrating for the dermatologist, child and parents alike as this chronic inflammatory skin disease is marked with numerous difficult to control flares. Although country specific guidelines for AD exist, there is paucity of data with respect to dedicated topical care regimens for AD management in pediatric population. Purpose: This is a broad based review exploring various topical practices and management options to manage pediatric AD during flares and in remissions. Scope: The PubMed database was searched (to 1 June 2020) for English-language articles containing the keywords atopic dermatitis, atopic eczema, topical calcineurin inhibitor(TCI), topical corticosteroid(TCS), topical phosphodiesterase inhibitors, crisaborole, topical therapy. Articles focusing on topical managment for children with AD were chosen for further review. A limitation is that this is not a systematic review of the literature. We have relied heavily on The Indian Dermatology Expert Board Members 2019 Management Guidelines on AD and the 2014 American Academy of Dermatology (AAD) guidelines, soon to be updated. In our review, we focus on Skin directed therapies to repair and maintain healthy skin barrier, suppress inflammatory response, control flares, control itch and manage infectious triggers. Topicals can be used as first line therapy in mild AD, adjuvant for moderate-severe AD or as maintenance to keep the disease in remission. Topical therapy in AD is not limited to TCS, TCI, Crisaborole or newer molecules but also involves moisturization, emollient care and bathing practices; which have been discussed. Conclusion: Multiple topical therapies and practices have been successfully used to treat children with AD. An understanding of the available treatment options will help dermatologists striving to achieve best practice in the management of pediatric AD.

Skin is our barrier against environmental damage. Moisturizers are widely used to increase hydration and barrier integrity of the skin; however, there are contrasting observations on their in vivo effects in real‐life settings. In cosmetic studies, corneometers and tewameters are traditionally used to assess skin hydration. In this study, two novel noninvasive diagnostic techniques, optical coherence tomography (OCT) and confocal Raman spectroscopy, were used to analyze stratum corneum and epidermal thickness (ET), water content, blood flow in function of depth, skin roughness, attenuation coefficient, natural moisturizing factor, ceramides and free fatty acids, cholesterol, urea, and lactates in 20 female subjects aged between 30 and 45 before and after 2 weeks application of a commercially available moisturizing lotion on one forearm. The untreated forearm served as control. A third measurement was conducted 1 week after cessation of moisturizing to verify whether the changes in the analyzed parameters persisted. We noticed a reduction in skin roughness, an increase in ceramides and free fatty acids and a not statistically significant increase in ET. As a conclusion, short time moisturizing appears insufficient to provide significant changes in skin morphology and composition, as assessed by OCT and RS. Novel noninvasive imaging methods are suitable for the evaluation of skin response to topical moisturizers. Further studies on larger sample size and longer treatment schedules are needed to analyze changes under treatment with moisturizers and to standardize the use of novel noninvasive diagnostic techniques.

Biosurfactants produced by a variety of microorganisms show attractive properties (e.g., higher surface activity and biodegradability, lower toxicity, and environmental compatibility) compared to chemically synthesized counterparts. The numerous advantages of biosurfactants have prompted their application to not only the food, cosmetic, and pharmaceutical industries, but agriculture and environmental protection disciplines as well. Among different types of biosurfactants, glycolipids are the most practically useful, due to their high product titers from renewable resources and versatile interfacial and biochemical properties. Mannosylerythritol lipids (MELs) are characteristic glycolipid biosurfactants that are produced by different yeast strains of the genus Pseudozyma. MELs exhibit different lyotropic liquid crystalline phases, such as sponge (L3), reverse bicontinuous cubic (V2), or lamellar (Lα) phases; and they have high levels of surface activity at very low concentrations. MELs also show excellent moisturizing effects on human skin and hair, with comparable performance to natural ceramides. Today, MELs are commercially produced by a Japanese company and their use is rapidly expanding around the world. In this review, we will briefly describe the current R&D status of glycolipid biosurfactants, with a focus on the interfacial properties of MELs and their applications in cosmetic and personal care products.

The use of skincare products is on the increase. On the market, there is a wide range of brands that are suitable for the whole consumer population. Due to the limited requirements for the good manufacturing of such products, the exposure of the consumer to potential benefits and risks is not normally taken into account. Five facial formulations from five brands were taken as an example to determine their potential benefits and risks. The characteristics of the twenty-five samples were studied by considering the unit price, the dry matter content, and color characteristics. The polyphenolic content, antioxidant activity, and heavy metal content were determined. The brands were categorized into high and low-end products. The dry matter content was significantly low for toners and in general cleansers and toners were colorless formulations whereas moisturizers, sunblocks, and eye creams were white in color, with some exceptions. Most of the formulations contained polyphenols, however, the anti-oxidant activity correlated weakly with polyphenols eluding that there are other anti-oxidant substances present. In general, the products contained a number of heavy metals (Cr, Cu, Fe, Ni, Pb, Zn) however all were devoid of Cd and Co. This study reveals that there are no significant differences in quality in terms of polyphenols, antioxidant activity, and heavy metal contamination. Authorities should consider stricter standards on the production of cosmetics, particularly those that are used on a daily basis. [ABSTRACT FROM AUTHOR]

Atopic dermatitis (AD) is a common, burdensome inflammatory skin disease. In recent years, multiple safe and effective monotherapy treatments directly targeting immune dysregulation in AD have been approved and integrated into clinical practice. Although the etiopathogenesis of AD is complex, it is widely recognized that alongside immune dysregulation, skin barrier disruption also plays an essential role in disease pathophysiology. For this reason, regular moisturization has been a foundational mainstay of therapy, consistently recommended by treatment guidelines regardless of disease severity or therapeutic approach. It is vital for healthcare providers to continuously educate patients and caregivers about the importance of optimizing skin barrier function by maintaining proper moisturization as part of their treatment plan and help them make data-driven decisions to navigate the wide array of available products.

The estrogen decrease in postmenopausal women results in functional and anatomical changes in the genitourinary tract. The most prevalent and bothersome symptoms are vaginal dryness, dyspareunia, and reduced lubrication, which can significantly affect the quality of life of these women, principally those who are sexually active. Hormonal therapy with local estrogens is generally considered the “gold standard.” However, there are cases in which there are clinical concerns about its use or women opt for non-hormonal options. Thus, safe and effective non-hormonal options are needed to improve symptoms in these women. Moisturizers and lubricants are first-line therapy for breast cancer survivors.

Abstract Atopic dermatitis/eczema is a chronic inflammatory skin condition, and emollients are the first-line treatment. Despite their widespread use, there is uncertainty about the frequency and type of adverse events associated with different emollients. We conducted a restricted review of published data on adverse events associated with emollient use in eczema. Medline (Ovid) was searched from inception (1946) to June 2018. All types of studies, with the exception of reviews, were included. Eligibility was assessed using a two-stage screening process against inclusion and exclusion criteria. References of all included papers were screened for any additional eligible papers. Data were subsequently extracted from all eligible publications. A limited body of data were found in the published data: 24 papers reported on adverse events with 29 different emollients (3 containing urea, 5 containing ceramide, 4 containing glycerol, 4 were herbal and 13 contained “other” ingredients). Interpretation of the results and comparison of the emollients were difficult due to poor reporting and missing data. Many publications contained no data at all on adverse events, and no study reported serious treatment-related adverse events for any emollient. The proportion of participants in the studies experiencing treatment-related adverse events varied between 2 and 59%. The most common adverse events were skin related and often mild. The range of participants experiencing non-treatment-related adverse events varied between 4 and 43%. From this restricted review, clinicians and patients can be reassured that the emollients studied appear to be generally safe to use. Better studies and reporting of adverse events associated with emollients in common use are needed.

Atopic dermatitis, the most common form of eczema, is a chronic, relapsing inflammatory skin condition that occurs with dry skin, persistent itching, and scaly lesions. This debilitating condition significantly compromises the patient’s quality of life due to the intractable itching and other associated factors such as disfigurement, sleeping disturbances, and social stigmatization from the visible lesions. The treatment mainstay of atopic dermatitis involves applying topical glucocorticosteroids and calcineurin inhibitors, combined with regular use of moisturizers. However, conventional treatments possess a certain degree of adverse effects, which raised concerns among the patients resulting in non-adherence to treatment. Hence, the modern use of moisturizers to improve barrier repair and function is of great value. One of the approaches includes incorporating bioactive ingredients with clinically proven therapeutic benefits into dermocosmetics emollient. The current evidence suggests that these dermocosmetics emollients aid in the improvement of the skin barrier and alleviate inflammation, pruritus and xerosis. We carried out a critical and comprehensive narrative review of the literature. Studies and trials focusing on moisturizers that include phytochemicals, natural moisturizing factors, essential fatty acids, endocannabinoids, and antioxidants were identified by searching electronic databases (PubMed and MEDLINE). We introduce the current knowledge on the roles of moisturizers in alleviating symptoms of atopic dermatitis. We then further summarize the science and rationale of the active ingredients in dermocosmetics and medical device emollients for treating atopic dermatitis. Finally, we highlight the limitations of the current evidence and future perspectives of cosmeceutical research on atopic dermatitis.

Moisturizers are one of the most widely used preparations in cosmetics and have been extensively used to soften the skin for consumers. Moisturizers work effectively in combating dry skin which may cause pain, tightness, itch, stinging, and/or tingling. The aim of this review is to evaluate published studies on the history, ingredients, preparation processes, characteristics, uses, and applications of moisturizers. Moisturizers bridge the gap between medicine and consumer goods by being used to make the skin more beautiful and healthy. In the future, in moisturizer therapy, the capacity to adapt specific agents to specific dermatological demands will be crucial. Cosmetically, moisturizers make the skin smooth by the mechanism of increasing the water content in the stratum corneum, hence exerting its most vital action, which is moisturizing action and maintaining a normal skin pH.
