Atopic dermatitis is a chronic and multifactorial inflammatory dermatosis. Recurrent eczematous lesions and intense pruritus very often reduce the quality of life of patients, affecting their mental health. For this reason, it is necessary to undertake treatment. Treatment should be characterized by an individual approach to the patient, taking into account the predominant pathogenetic factors in the development of atopic dermatitis and systematic skin care. Soothing the typical symptoms of AD, i.e., dry skin and persistent itching, involves emollients, which counteract xerosis and reduce the feeling of itching. Studies confirm that the regular use of emollients in patients with AD prolongs the period between relapses and alleviates the intensity of symptoms during periods of disease severity. This review paper aims to highlight the challenges that patients with atopic dermatitis face. This work will also present an indication of the rationale for the use of emollients in this condition, as well as an indication of the forms of their application in therapeutic and care preparations.

Dry skin is a common dermatological condition that frequently affects the elderly. A contributing cause to dry skin is a reduced concentration of hyaluronic acid (HA) in both the epidermis and dermis. The effectiveness of moisturizer containing HA as a therapy for dry skin is impacted by its specific molecular weight. Low molecular weight HA (LMWHA) is believed to be more effective in replenishing skin hydration in aging skin compared to High Molecular Weight HA (HMWHA) due to its ability to penetrate the stratum corneum. However, there is a lack of clinical research supporting this claim. A double-blind, randomized controlled trial was conducted on 36 residents of a nursing home in Jakarta. The participants, aged between 60 and 80 years, had been diagnosed with dry skin. Each test subject was administered three distinct, randomized moisturizing lotions (LMWHA, HMWHA, or vehicle), to be topically applied to three separate sites on the leg. Skin capacitance (SCap), transepidermal water loss (TEWL), and specified symptom sum score (SRRC) were measured at weeks 0, 2, and 4. After four weeks of therapy, area that was treated with LMWHA showed greater SCap values compared to the area treated with HMWHA (56.37 AU vs. 52.37 AU, p = 0.004) and vehicle (56.37 AU vs. 49.01 AU, p < 0.001). All groups did not show any significant differences in TEWL and SRRC scores. No side effects were found in all groups. The application of a moisturizer containing LMWHA to the dry skin of elderly resulted in significant improvements in skin hydration compared to moisturizers containing HMWHA and vehicle. Furthermore, these moisturizers demonstrated similar safety in treating dry skin in the elderly. ClinicalTrials.gov Identifier NCT06178367, . [ABSTRACT FROM AUTHOR]

Background and Aims: Skin aging is associated with dry skin and a decrease of the strength of the dermoepidermal adhesion, which increases the risk for lacerations (skin tears). Application of leave‐on products improves dry skin and seems to reduce skin tear incidence. The aim of this study was to measure the effects of a humectant containing leave‐on product on the strength of the dermoepidermal junction in older adult participants with dry skin. Methods: A randomized controlled trial using a split body design was conducted. One forearm was randomly selected and treated with a lipophilic leave‐on product containing 5% urea for 8 weeks. The other forearm was the control. The parameters stratum corneum hydration (SCH), transepidermal water loss, pH, roughness, epidermal thickness and skin stiffness were measured at the baseline, Weeks 4 and 8. At Week 8, suction blisters were created and time to blistering was measured. Blister roofs and interstitial fluid were analyzed for Interleukin‐1α, 6 and 8. Results: Twelve participants were included. After 8 weeks treatment, SCH was higher (median difference 11.6 AU), and the overall dry skin score (median difference −1) and median roughness (Rz difference −12.2 µm) were lower compared to the control arms. The median group difference for Interleukin‐1α was −452 fg/µg total protein (TP) in the blister roofs and −2.2 fg/µg TP in the blister fluids. The median time to blister formation was 7.7 min higher compared to the control arms. Conclusion: The regular application of humectant containing leave‐on products improves dry skin and seems to lower inflammation and contribute to the strengthening of the dermoepidermal adhesion. This partly explains how the use of topical leave‐on products helps to prevent skin tears. [ABSTRACT FROM AUTHOR]

The current study focuses on the synthesis of gold nanoparticles (AuNPs) using the plum peel extract obtained by deep eutectic solvent (DES) (Betaine-Urea and Choline chloride-Urea). Formation mechanism of DESs and molecular interactions between components has been studied using quantum chemical methods. DESs have been used for obtaining extracts from plum peel. It has been established that the reducing ability of extracts obtained using DESs is higher (489–580 mg ASE/g extract) than when using a traditional aqueous-alcohol solution (336 mg ASE/g extract). Gold nanoparticles were characterized by UV–vis spectroscopy, FTIR, and SEM-XRD analysis. The size of AuNPs was found to be 5–10 nm as per the particle size analyzer, and the zeta potential is − 46 to 47 mV. The scavenging ability of the sample solution to ABTS radical was determined by ABTS radical scavenging test. The AuNPs synthesized by extracting Cl-U exhibited significant antioxidant potential against ABTS•+, with an IC50 of 110 mg/mL. For the first time in a cosmetic product, AgNPs synthesized by plum peel extract in a deep eutectic solvent was used. The creams were evaluated for their organoleptic characteristics, physicochemical properties, and in vitro antibacterial activity against Escherichia coli and Bacillus subtilis. Results show that the cream with 0.5% AuNp increases the value of moisturizer for the skin.

[Display omitted] • The 400 µm long DMNs penetrate the skin to a depth of ≈200 µm for dry skin and ≈200–290 µm for the barrier-disrupted skin. • The dissolved polymer expands more expansively in barrier-disrupted skin than in intact skin, with the smallest expansion observed in dry skin. • The DMNs-induced microchannel areas are significantly more pronounced in barrier-disrupted and dry skin than in intact skin. • To optimize DMN-induced drug delivery, it is essential to select a suitable skin model, considering the skin conditions and the dissolvability of needle materials. Dissolvable microneedles (DMNs), fabricated from biocompatible materials that dissolve in both water and skin have gained popularity in dermatology. However, limited research exists on their application in compromised skin conditions. This study compares the hyaluronic acid-based DMNs penetration, formation of microchannels, dissolution, and diffusion kinetics in intact, barrier-disrupted (tape stripped), and dry (acetone-treated) porcine ear skin ex vivo. After DMNs application, comprehensive investigations including dermoscopy, stereomicroscope, skin hydration, transepidermal water loss (TEWL), optical coherence tomography (OCT), reflectance confocal laser scanning microscopy (RCLSM), confocal Raman micro-spectroscopy (CRM), two-photon tomography combined with fluorescence lifetime imaging (TPT-FLIM), histology, and scanning electron microscopy (SEM) were conducted. The 400 µm long DMNs successfully penetrated the skin to depths of ≈200 µm for dry skin and ≈200–290 µm for barrier-disrupted skin. Although DMNs fully inserted into all skin conditions, their dissolution rates were high in barrier-disrupted and low in dry skin, as observed through stereomicroscopy and TPT-FLIM. The dissolved polymer exhibited a more significant expansion in barrier-disrupted skin compared to intact skin, with the smallest increase observed in dry skin. Elevated TEWL and reduced skin hydration levels were evident in barrier-disrupted and dry skins compared to intact skin. OCT and RCLSM revealed noticeable skin indentation and pronounced microchannel areas, particularly in barrier-disrupted and dry skin. Additional confirmation of DMN effects on the skin and substance dissolution was obtained through histology, SEM, and CRM techniques. This study highlights the impact of skin condition on DMN effectiveness, emphasizing the importance of considering dissolvability and dissolution rates of needle materials, primarily composed of hyaluronic acid, for optimizing DMN-based drug delivery.

Older nursing home residents are prone to develop different skin conditions at the same time, including xerosis cutis, skin tears, pressure ulcers, incontinence-associated dermatitis or intertrigo. Guidelines and recommendations mainly address these skin conditions separately. The overall aim of this study was to measure the effects of the implementation of a skincare and prevention package. A two-arm cluster-randomised controlled trial was conducted. In nursing homes being assigned to the intervention group, an evidence-based and structured skincare and prevention programme was implemented for six months. Nursing home residents in the control group received standard care as usual. Blinded dermatologists conducted head-to-toe skin assessments, and the researchers assessed skin barrier parameters including stratum corneum hydration and transepidermal water loss at the upper and lower extremities after three and six months. Outcomes included the cumulative incidence of incontinence-associated dermatitis, skin tears, pressure ulcers and intertrigo, and were presented as intention-to-treat and per protocol analysis. Skin dryness and resident-reported outcomes (pain, itch, quality of life) were assessed. A random sample of 17 nursing homes in the federal state of Berlin, Germany, was drawn and randomised in intervention (n = 9) and control groups (n = 8). In total, 165 participants were allocated to the intervention, and 149 participants were allocated to the control group. The cumulative incidence of skin tears (19.2 %, 95 % CI 12.8–27.8), pressure ulcers (13.6 %, 95 % CI 8.1–21.9) and intertrigo (27.0 %, 95 % CI 18.4–37.7) was lower in the intervention compared to the control group, with cumulative incidences of 27.2 % (95 % CI 19.3–36.9) for skin tears, 16.9 % (95 % CI 10.6–25.9) for pressure ulcer, and 37.8 % (95 % CI 27.5–49.4) for intertrigo. The incidence of incontinence-associated dermatitis was higher in the intervention group (26.3 %, 95 % CI 17.9–36.8) compared to the control group (23.1 %; 95 % CI 14.6–34.5). Mean skin dryness was lower in the intervention group but showed variation. The impact on pain, itch, and quality of life was trivial. The present study results indicate that the implementation of tailored and evidence-based nursing routines improves skin health and safety in residential long-term care. Evidence suggests that multiple adverse skin conditions can be prevented by regular skin assessments and individually tailored skincare routines. Positive effects on skin dryness were observed, but skin physiology parameters did not indicate changes of the skin barrier function.
