Background: Neck rejuvenation has consistently become a popular cosmetic procedure. While various treatment modalities have been used, a novel fractional thermomechanical skin rejuvenation system was recently developed to create dermal coagulation through direct heat transfer with subsequent neocollagenesis., Objective: A prospective clinical trial evaluated the efficacy and safety of a thermomechanical fractional injury device (Tixel 2, Novoxel, Netanya, Israel) for neck rhytides., Materials and Methods: Subjects with moderate to severe neck rhytides were enrolled for 4 monthly treatments., Results: Twenty-six subjects were enrolled and completed all study visits. The mean age was 58.4 years, and 100.0% were women. Fitzpatrick skin types I to IV were included. For Fitzpatrick Wrinkle Classification System (FWCS), the mean baseline score was 6.3. As per investigator, there was a mean 1.5-grade improvement in FWCS at 1-month follow-up (p < .00001) and 1.4-grade improvement in FWCS at 3-month follow-up (p < .00001). For physician Global Aesthetic Improvement Scale, all subjects (100%) had improvement at both 1- and 3-month follow-up visits. There were no severe adverse events, and subjects experienced minimal pain., Conclusion: A novel thermomechanical fractional injury device is effective and safe for the treatment of neck rhytides., (Copyright © 2024 by the American Society for Dermatologic Surgery, Inc.

Investigating the correlation between aging mechanisms and state of charge (SOC) can optimize cycling conditions and prolong the life cycle of lithium-ion batteries (LIBs). A long-term cycle between a certain SOC range is usually employed to study this correlation. However, this method necessitates a lengthy period, running from months to years, prolonging the research duration significantly. The aging mechanisms obtained through this method are a result of the coupling of various SOC levels; the aging mechanisms at a specific SOC level are not accurately decoupled and analyzable. The proposed Zero-sum pulse method, using symmetrical pulses with small SOC amplitude variations on SOC, can explore aging mechanisms of LIBs at a specific SOC level and reduce the time to less than a week, which significantly expedite the research process. The aging mechanisms at 30%, 50%, 70%, and 90% SOC levels are explored to verify the accuracy and timeliness of this method., Competing Interests: The authors declare no competing interests., (© 2024 The Authors.

The mass transfer in lithium-ion batteries is a low-frequency dynamic that affects their voltage and performance. To find an effective way to describe the mass transfer in lithium-ion batteries, a simplified electrochemical lithium-ion battery model based on ensemble learning is proposed. The proposed model simplifies lithium-ion transfer in electrode particles with ensemble learning which ensembles discrete-time realization algorithm (DRA), fractional-order Padé approximation model (FOM), and three parameters (TPM) parabolic. The lithium-ion transfer in the electrolyte is simplified by the first-order inertial element (FIE). The results show that the proposed model achieves not only accurate lithium-ion concentration prediction in solid and electrolyte phase but also precise voltage prediction with low computational complexity., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2024 The Author(s).)

Background: Patients frequently seek laser treatment for vascular conditions. More recently, a novel 532 and 1,064 nm laser was developed to offer greater flexibility., Objective: A prospective clinical trial evaluated the safety and efficacy of a novel, variable-sequenced, long-pulsed, 532 and 1,064 nm laser with cryogen spray cooling (DermaV, Lutronic, South Korea)., Materials and Methods: Subjects with vascular conditions were enrolled for laser treatments.

Background: Dyschromia can be associated with increased production and/or reduced clearance of pigmentation in the skin. Multiple pathways are involved in causality. A novel topical product was recently developed, which contains actives that have been validated through in-vitro and clinical studies to counteract pigmentation related to photodamage, PIH, and melasma. This study further evaluates the safety and efficacy of this product for facial dyschromia during an additional 3-month extension period following the completion of the previous 12-week multi-center trial.&nbsp; Study Design: Subjects from the previous multi-center trial with mild to severe facial dyschromia at baseline were eligible to participate in this 3-month extension study upon completion of that trial. This extension study evaluated the continued use of the novel topical product with PATH-3 Technology (Alastin Skincare, Carlsbad, CA) over a 3-month period. Subjects who were previously randomized to the novel topical product continued using it and for those previously randomized to hydroquinone 4% discontinued its use. Both cohorts continued daily sunscreen use. Blinded investigators assessed subjects at follow-up visits at 16, 20, and 24 weeks., Results: Twenty-six (26) subjects completed the extension phase of the pivotal trial, with 13 subjects in each of the AL and HQ-BREAK cohorts. Significant improvements were seen within the AL cohort from weeks 12 to 24 for facial dyschromia (P=0.0158) and skin tone/clarity/evenness (P=0.0067), while there were no significant improvements seen in the HQ-BREAK cohort. The HQ-BREAK cohort had more subjects who worsened with facial dyschromia and skin tone/clarity/evenness. For the mMASI, the HQ-BREAK cohort demonstrated regression at week 24 compared to week 12, while the AL cohort instead experienced continued improvement. This difference was found to be significant (P=0.02). No study-related adverse events were reported for either cohort.&nbsp; Conclusion: A novel topical product designed to counteract various steps in pigmentation pathways using PATH-3 Technology has been demonstrated to be safe and effective in treating facial dyschromia on a long-term basis. In contrast to the significant rebound experienced by subjects with HQ, the AL cohort continued to demonstrate ongoing improvement.

Recently, the addition of moringa to skincare products has become a popular trend, especially in the natural beauty industry. It is being marketed for its intended moisturizing, antioxidant, and anti-aging properties; however, data are scarce demonstrating its clinical effects as well as standardized concentration, formula, source, and extraction methods. Skin specialists must be aware of this trendy ingredient, including its recent claims in marketing material and current evidence in the literature.

Background: Cosmetic tattoos in the periocular area, including microblading, have become increasingly popular. More patients have been seeking laser tattoo removal. OBJECTIVE: A retrospective chart review for the laser treatment of eyeliner and eyebrow tattoos and a discussion of treatment experiences can better inform physicians., Methods: A retrospective chart review was performed over five years with patients who had eyeliner and/or eyebrow tattoos and had laser removal., Results: Overall, 76 patients were treated. Mean age was 47 years, and 98.7 percent were women. Fitzpatrick Skin Types I-VI were represented. Of all cases, 55.3 percent included eyebrows, 43.4 percent eyelids, and 1.3 percent both. There was a mean of 2.8 treatments. Common colors included black (73.7%), black/red (7.9%), black/orange (5.3%), black/yellow (3.9%), and red (3.9%). Most cases were treated with 755nm picosecond laser or high peak-powered 532nm/1064nm picosecond laser. After initial treatment, 26.3 percent of cases involved unmasking of colors, such as red, orange, yellow, green, and blue, which were not previously visualized. There were no documented adverse events related to scarring, hypotrichosis, necrosis, and burns., Conclusion: Laser removal of eyeliner and eyebrow tattoos can be safe and effective.

Growing a cosmetic dermatology practice is an often complex and arduous task. Many factors must be considered to build and maintain a successful clinical practice. Devices and injectables are both integral components to operating a comprehensive cosmetic dermatology practice. Aesthetic physicians seeking to grow their cosmetic practice in these areas must be aware of the numerous considerations-both more obvious and more subtle-that play a role in the decision-making process, including the local market, patient demand, clinic space, and physician experience and training. This contribution is focused on the factors that should be carefully considered when one is looking to grow a cosmetic dermatology practice with devices and injectables., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023.

A rising demand for dermatologic procedures has led to a recent increase in the number of non-physician operators (NPOs) in the dermatology workforce. Nurse practitioners, physician assistants, and aestheticians commonly perform procedures in both physician-based practices and medical spas with varying degrees of dermatology-specific training and physician oversight. Although the lack of regulations can negatively impact patient outcomes and adverse events, the role of NPOs in dermatology continues to grow. Among Medicare beneficiaries, nurse practitioners and physician assistants are independently billing for a growing number of dermatologic procedures, whereas the number performed by dermatologists remains relatively stable. Medical spas are an increasingly popular destination for aesthetic consumers, and the majority employ only NPOs as primary providers. Recent data suggest that compared to dermatologists, NPOs have a higher rate of adverse events. As attempts are made to standardize and improve the training requirements for dermatologic procedures, a concerted effort should be made to prioritize patient outcomes and safety., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Inc.

Melasma is a chronic cutaneous condition that not only affects the appearance of patients but also has an immense psychosocial impact on patient quality of life. Although many treatment options are currently available, there is no single universal treatment regimen that works for all patients. Significant attention has been recently focused on the development and use of topical treatments that can lighten the dark patches associated with melasma. One such ingredient that has received growing attention in recent years is cysteamine. It works through several mechanisms to influence the melanogenesis pathway. This commentary reviews the information on this topical ingredient and offers relevant clinical insights.

Background: Energy-based devices, such as nonablative lasers, are a promising method to enhance the delivery and absorption of topically applied molecules., Objective: To characterize ex vivo uptake of common antioxidant topicals after pretreatment with a nonablative laser wavelength., Materials and Methods: Using donor human skin tissue, uptake of 3 topical antioxidants was analyzed (C E Ferulic with 15% l-ascorbic acid [15% vitamin C serum], Phloretin CF with ferulic acid [10% vitamin C serum], and Phyto+ [botanical serum]; SkinCeuticals, Dallas, TX; 2010 formulations) after pretreatment with a 1,440-nm nonablative fractional diode laser., Results: Pretreatment with the 1,440-nm laser enhanced uptake of 15% and 10% vitamin C serums by approximately 10 and 21 times, respectively, compared to controls. Laser pretreatment also enhanced uptake of botanical serum by approximately 6 times relative to controls. Permeation of vitamin C and botanical serums was also enhanced through laser pretreatment., Conclusion: Nonablative laser pretreatment increased uptake and permeation of topical antioxidants. Optimizing treatment requires consideration of the device and treatment parameters as well as the properties of the topical formulation., (Copyright © 2022 by the American Society for Dermatologic Surgery, Inc.

Platelet-rich plasma (PRP) has gained tremendous traction for a broad variety of indications within regenerative medicine. Despite a lack of standardized literature assessing efficacy and best practice procedures for preparation, PRP has become increasingly utilized for cutaneous rejuvenation. In this review, we highlight the many variations that may affect the quality and effectiveness of PRP, while also outlining the highest quality evidence that exists for facial rejuvenation. In reviewing the use of PRP for this indication, most high-quality evidence suggests subtle to modest clinical improvement, with many studies demonstrating conflicting results. Additional high-quality investigative work with clearly delineated methodologies is needed in order to better understand the role of PRP., (© 2022.

Background: Laser pretreatment with cosmeceutical topicals is growing in popularity. However, lasers may also enhance the uptake of medical topicals that treat dermatologic conditions, such as vitiligo, alopecia, and cancerous and precancerous lesions. Permeation of these topicals must be quantified to optimize treatment protocols., Objective: To analyze transdermal uptake of 3 topicals after nonablative fractional 1,550-nm erbium-doped glass or 1,927-nm thulium fiber laser pretreatment., Methods and Materials: Human donor tissue was pretreated with a nonablative fractional 1,550-nm erbium-doped glass or 1,927-nm thulium fiber laser followed by application of 0.03% bimatoprost, 0.5% 5-fluorouracil, or 5% minoxidil. Permeation and retention were measured over 24 hours (bimatoprost and 5-fluorouracil) or 90 minutes (minoxidil), and uptake was calculated., Results: Pretreatment with 1,927-nm thulium laser (500 MTZ/cm2; 5 mJ; 5 W) enhanced uptake and retention of bimatoprost versus untreated control at 24 hours post-treatment. Pretreatment with 1,550-nm erbium-doped glass laser (2,000 MTZ/cm2; 10 mJ; 30 W) enhanced permeation, uptake, and retention of 5-fluorouracil at 24 hours post-treatment and enhanced permeation and uptake of minoxidil at 90 minutes post-treatment., Conclusion: Nonablative laser pretreatment may enhance topical treatment of dermatologic conditions. Device settings must be optimized to maximize topical permeation while minimizing laser-associated thermal side effects., (Copyright © 2022 by the American Society for Dermatologic Surgery, Inc.

Background: The uptake of topical formulations can be enhanced through laser pretreatments. Newer technologies, such as non-ablative fractional lasers (NAFLs), can target dermal tissues and spare the stratum corneum (SC), which can mitigate common side effects associated with ablative laser treatment., Objective: To discuss the parameters of 2 NAFL pretreatment systems (1440-nm/1927-nm diode system or 1550-nm erbium-doped glass/1927-nm thulium system), which can be paired with topicals to improve their cutaneous uptake., Methods and Materials: The parameters of the 1440-nm/1927-nm diode system and 1550-nm erbium-doped glass/1927-nm thulium system were reviewed, as well as in vivo experiments using both laser systems., Results: Multiple parameters should be optimized to enhance the uptake of various topical formulations and minimize side effects, including wavelength, spot size, density, pulse duration, thermal properties, and topical formulation. Chosen therapeutic parameters must account for patient-specific factors, such as treatment indication, therapeutic area, and Fitzpatrick skin type. In vivo experiments have demonstrated that both laser systems are effective in enhancing the uptake of various topical therapies relative to untreated controls., Conclusion: Individualization of laser system parameters increases efficiency and minimizes risk., (© 2022 Wiley Periodicals LLC.)

Papulosquamous diseases represent a commonly encountered group of cutaneous disorders in dermatology. Lesions can present with papules and plaques in various configurations, including annular forms. Some of these disorders are expected to appear in annular configurations, such as pityriasis rosea and subcorneal pustular dermatosis. Others may either begin as or even progress to annular configurations, including psoriasis vulgaris, seborrheic dermatitis, and nummular dermatitis. We have reviewed common papulosquamous diseases that can present with annular lesions, which includes psoriasis vulgaris, pityriasis rosea, subcorneal pustular dermatosis, contact dermatitis, seborrheic dermatitis, and nummular dermatitis. For each disorder, we have discussed the details of presentation and differential diseases to be considered., (Copyright © 2022 Elsevier Ltd. All rights reserved.)

Background: Although the stratum corneum limits transdermal absorption of topicals, laser devices can enhance topical uptake by disrupting the skin barrier. Nonablative lasers are commonly used, but their effects on topical uptake should be quantified to optimize outcomes., Objective: The objective of this study is to analyze transdermal uptake of 4 topicals after nonablative fractional diode laser pretreatment., Methods and Materials: Human donor tissue was pretreated ex vivo with a nonablative fractional diode laser (1,927 nm or 1,440 nm, at varying treatment densities, powers, and peak energies) followed by application of either 2% salicylic acid, 10% ascorbic acid, over-the-counter mineral eye serum, or 4% hydroquinone. Topical uptake was quantified over 24 hours., Results: Despite lower power settings, pretreatment with the 1,927 nm wavelength was associated with greater uptake of 10% ascorbic acid, mineral eye serum, and 4% hydroquinone than the 1,440 nm wavelength. In addition, 1,440-nm laser pretreatment with higher density (320 microscopic treatment zones [MTZ]/cm 2 ) and peak power (3 W) was associated with similar uptake but greater retention of 2% salicylic acid and greater uptake of 10% ascorbic acid than that with lower density (80 MTZ/cm 2 ) and peak power (1.2 W)., Conclusion: When using laser pretreatment, device settings should be adjusted to balance outcomes with potential side effects., (Copyright © 2022 by the American Society for Dermatologic Surgery, Inc.

Over the years, health disparities in medicine have continued to grow, and dermatology has been especially impacted, given the relative shortage of dermatologists in comparison to patient needs. Novel and disruptive solutions may be required to help improve patient care. In 2013, Google Glass was introduced, which is a wearable head-mounted display. The device is analogous to having a computer connected to your eyeglasses with one of the lenses serving as the screen. The technology has already been introduced for various applications within the medical field. We reviewed the pros and cons of this technology, with specific focus on dermatologic care, and discussed how Google Glass could potentially address current dermatologic health disparities. ( SKINmed . 2022;20:187-189).

The field of cosmetic dermatology has recently witnessed unbridled growth in the past several years. Part of this has been due to the increasing popularity of aesthetic treatments in men, who represent a growing patient population. Men tend to have higher levels of collagen density and greater skin thickness, but these begin to decrease earlier on. They can also more frequently have severe photodamage. Their clinical presentations can affect the selection of treatments. Physicians should be familiar with the subtle differences between treating men and women. Early studies and literature are beginning to shed more light on these important distinctions. We review the notable differences in facial aging, pathophysiology, and patient selection and discuss available treatment options with these factors in mind., (Copyright © 2021 Elsevier Ltd.

Consumer interest in aesthetic procedures continues to grow. Through savvy marketing, affordable pricing, and minimal wait times, medical spas have grown in number to where they now outnumber physician-based cosmetic practices in 73% of major U.S. cities. To staff these facilities, owners frequently turn to nonphysician operators who have variable levels of training in dermatology and cosmetics. There has been a lack of uniform standardization of training and oversight, which may contribute to adverse events, such as burns, pigmentary alterations, and scarring. As the market for noninvasive and minimally invasive cosmetic procedures continues to grow, physicians should be informed about the current cosmetic landscape in which they practice to improve patient awareness, education, and safety., (Copyright © 2021 Elsevier Ltd.
