Evaluating the Use of IncobotulinumtoxinA in Combination with Calcium Hydroxylapatite with Integral Lidocaine for Improving Chin Profile Projection Aesthetics.

Background: Microgenia resulting from congenital deficiency or aging can significantly affect the facial profile and render it less attractive. This study assessed the effectiveness of treatment with incobotulinumtoxinA (Inco) and calcium hydroxylapatite with integral lidocaine (CaHA[+]) for improving chin profile. Methods: Subjects with a hyperactive mentalis and at least moderate chin retrusion according to the Asian Chin Projection Scale (ACPS) were recruited. At Visit 1, subjects received Inco injection into the mentalis, followed by deep, pre-periosteal injections of CaHA(+) into the pogonion. The primary endpoint was an ACPS improvement of one point at one and six months. Photographs at baseline and each follow-up visit were rated by physicians using the Global Aesthetic Improvement Scale (GAIS). All subjects completed a satisfaction questionnaire. Results: Ten female subjects were recruited. Mean age was 42.5 years and all had moderate-to-severe chin retrusion at baseline (ACPS score ≥2). All subjects demonstrated at least a one-point improvement in ACPS compared with baseline at both the one-month and six-month posttreatment visits. Physician GAIS ratings of subject appearance confirmed that 100 percent of subjects experienced improved chin projection at each follow-up visit compared to baseline. All 10 subjects were pleased with their chin profile after treatment, with 90 percent noting that it was still "very much improved" at six months. Conclusion: Based on our results, combined treatment with CaHA and Inco appears to be effective and well tolerated for improving the facial profile of subjects with chin retrusion. Treatment was associated with a high degree of patient satisfaction and was well tolerated.

Novel, Validated, 5-Point Photonumeric Scales for Assessment of the Perioral Region.

BACKGROUND: The use of validated scales is still considered the gold standard for evaluating the severity of an aesthetic facial condition. OBJECTIVES: The aim of this investigation was to create and validate 5-point photonumeric scales for the assessment of perioral lines and marionette lines. METHODS: A medical team created 2 different novel 5-point photonumeric scales for the assessment of perioral lines and marionette lines. Eleven international raters were involved in the digital validation, and 4 raters performed a live validation. RESULTS: For the Croma Static Perioral Lines-Assessment Scale, the digital interrater intraclass correlation coefficients (ICCs) were 0.88 (95% CI, 0.85-0.91) in the first rating and 0.87 (95% CI, 0.83-0.90) in the second rating. The digital intrarater ICCs were 0.90 (95% CI, 0.87-0.92). In the live rating, the interrater ICCs were 0.89 (95% CI, 0.85-0.93) in the first rating and 0.91 (95% CI, 0.87-0.93) in the second rating with an intrarater ICC of 0.91 (95% CI, 0.88-0.95). For the Croma Marionette Lines-Assessment Scale, the digital rating interrater ICCs were 0.85 (95% CI, 0.81-0.89) in the first rating and 0.87 (95% CI, 0.84-0.90) in the second rating with an intrarater ICC of 0.89 (95% CI, 0.88-0.91). In the live rating, the interrater ICCs were 0.73 (95% CI, 0.54-0.83) in the first rating and 0.79 (95% CI, 0.65-0.87) in the second rating with an intrarater ICC of 0.88 (95% CI, 0.83-0.94). CONCLUSIONS: The Croma Static Perioral Lines-Assessment Scale and the Croma Marionette Lines-Assessment Scale have exceptional inter- and intrarater agreements that justify their use in clinical and study settings for all ethnic groups.

Novel, Validated 5-Point Photonumeric Scales for Assessment of the Neck and Décolleté.

BACKGROUND: There is a scarcity of scales that assess platysmal bands, wrinkles in the décolleté, and horizontal neck lines in the digital and live setting. OBJECTIVES: The objective of this investigation was to create and validate 5-point photonumeric scales that assess horizontal neck lines, platysmal bands, and wrinkles in the décolleté. METHODS: A medical team created 3 different novel 5-point photonumeric scales for the assessment of horizontal neck lines, platysmal bands, and décolleté wrinkling. Eleven international raters were involved in the digital validation, and 4 raters performed a live validation. RESULTS: The Croma (Leobendorf, Austria) Horizontal Neck Lines Assessment Scale showed substantial interrater agreement and almost perfect intrarater agreement in the digital and live validations, respectively. The Croma Platysmal Bands Assessment Scale showed substantial intrarater agreement in both digital and live validations. For the décolleté, a static scale and a dynamic scale were created and validated. The Croma Static Décolleté Wrinkles Assessment Scale showed substantial and almost perfect interrater agreement in the digital and live validations, respectively, and the intrarater agreement in both was almost perfect. The Croma Dynamic Décolleté Wrinkles Assessment Scale showed almost perfect agreement in both validation settings for both interrater and intrarater measures. CONCLUSIONS: The Croma Horizontal Neck Lines Assessment Scale and the Croma Static and Dynamic Décolleté Wrinkles Assessment Scales have sufficient interrater and intrarater agreement for justifiable use in clinical and research settings.

Review of the microbiome in skin aging and the effect of a topical prebiotic containing thermal spring water.

BACKGROUND: Interest in the skin microbiome and the cosmetic benefits of probiotics, prebiotics, and postbiotics is increasing. AIM: The current review explores the influence of the skin microbiome on facial skin aging and the effects of oral and topical probiotics, prebiotics, and postbiotics use on skin aging and cosmetic outcomes. METHODS: Five dermatologists who treat clinical signs of facial skin aging and a microbiome scientist (advisors) explored the relationship between the skin microbiome and skin aging. Published evidence and the advisors' knowledge lead to guidance on the skin microbiome using oral and topical prebiotics, probiotics, and postbiotics to reduce signs of aging. RESULTS: The role of the microbiome in aging skin is an emerging concept. A diverse skin microbiome is essential for skin health. Preliminary studies suggest oral probiotics and prebiotics may play a role in reducing signs of skin aging, likely through shifting to a greater skin and gut microbiome diversity. Thermal spring water contains probiotics and prebiotics. Preliminary studies suggest topically applied probiotics, prebiotics, and postbiotics may improve signs of skin aging, including a reduction in fine lines and increased hydration. CONCLUSIONS: The panel agreed that oral and topical prebiotics, probiotics, and postbiotics may play a role in improving signs of aging by improving the skin microbiome. Larger studies with more prolonged treatment trials are needed to better understand the microbiome's role in skin aging and the possible benefits of prebiotics, probiotics, and postbiotics use.

Characterization of a live Cutibacterium acnes subspecies defendens strain XYCM42 and clinical assessment as a topical regimen for general skin health and cosmesis.

BACKGROUND: When formulating topical products to treat skin diseases and addressing general skin health and cosmesis, most of the focus has traditionally been placed on how any given ingredient may impact the structure, function, and health of human skin elements. However, recent research is beginning to highlight the importance of the skin microbiome in relation to certain skin conditions and general cosmesis. Cutibacterium acnes is one of the most prolific skin-specific bacterial species. Research has shown that the species is divided into subspecies, some of which are thought to be beneficial to the skin. This paper aims to determine the efficacy of strainXYCM42, a C. acnes subspecies defendens derived strain designed to improve the health and appearance of the skin. METHODS: In vitro studies were performed on human keratinocyte and fibroblast monolayers, human peripheral blood mononuclear cells (PBMC), and skin explants to elucidate the effects of live XYCM42 cells and their ferment on human skin cells and tissues. Subsequently, clinical studies were performed using XYCM42-based topical regimens designed to deliver and support the engraftment of live XYCM42 cells onto subjects' skin. Two studies were performed, a 3-week pilot study (n = 10) and a 8-week pivotal study (n = 121). In the latter, 32 subjects were enrolled for an in-clinic portion for efficacy evaluation, with clinic visits occurring at Baseline, Week 1, Week 4, and Week 8. RESULTS: In vitro data suggest that XYCM42 and its ferment filtrate have potential to provide benefits to the skin via antioxidant, anti-inflammatory, and select antimicrobial activities. Clinical observation demonstrated that a XYCM42-containing regimen supports a healthy skin environment, promotes increased skin hydration, decreases erythema, calms the skin, and regulates sebum production. CONCLUSION: These studies provide further evidence that specific strains of C. acnes, such as XYCM42, have a more beneficial function regarding skin health and appearance than was previously thought. Appropriate use of formulations derived from symbiotic strains within the skin microbiome can support the development of novel, beneficial topicals.

Validated 5 - Point photonumeric scales for the assessment of hand atrophy.

OBJECTIVE: Quantifying the degree of dorsal hand atrophy is a challenging endeavor, but often necessary, in both the clinical and the research setting. The aim of this investigation was to create and consecutively validate a 5-point photonumeric scale for assessment of dorsal hand atrophy. MATERIAL AND METHODS: A medical team created a novel 5-point photonumeric scale. Twelve international raters were involved in the digital validation, while five raters performed a live validation. RESULTS: For the digital validation of the Croma Hand Atrophy Assessment Scale, a total of 72 subjects (58 females, 14 males) with a mean age of 43.0 ± 14.4 years [18-73 years] were assessed. For the live validation, 88 subjects (73 females, 15 males) with a mean age of 45.0 ± 14.1 years [20-73 years] were rated. The results revealed almost perfect intra-rater (ICC: 0.90 [95% CI: 0.88-0.92]) and inter-rater agreements (ICC: 0.85 [95% CI: 0.81-0.89] and 0.86 [95% CI:0.82-0.89]) in the digital validation and substantial intra-rater (ICC: 0.79 [95% CI: 0.75-0.82]) and inter-rater agreements (ICC: 0.75 [95% CI: 0.68-0.81] and ICC: 0.67 [95% CI: 0.54-0.77]) in the live validation. CONCLUSION: The created scale to assess dorsal hand atrophy has been shown to provide substantial-to-almost perfect agreement in the digital and live validation cycles and reached comparable intra-rater and inter-rater agreement to already published and validated scales. It is expected that the created scale will help physicians and researchers in the assessment of hand atrophy in the clinical and research setting in the future.

Non-ablative Er:YAG laser is an effective tool in the treatment arsenal of androgenetic alopecia.

BACKGROUND: Up to 70% of the adult population worldwide is affected by androgenetic alopecia (AGA) hair loss. Laser therapy offers an addition or alternative to pharmaceutical and surgical treatment of hair regrowth, with non-ablative lasers being preferred over ablative lasers in terms of safety and downtime. Combining laser therapy with different topical agents may result in better hair regrowth. OBJECTIVE: The aim was to evaluate the effectiveness and safety of non-ablative Er:YAG laser used in clinical practice, alone or in combination with other treatment modalities, in patients with both early and advanced stages of AGA. METHODS AND PATIENTS: Sixteen patients (7 male and 9 female) with active AGA in different stages were treated with the non-ablative Er:YAG laser (SMOOTHTM mode, 7 mm spot size, 7.00 J/cm2 pulse fluence, 3.3 Hz frequency) as a monotherapy or in combination with injections of platelet-rich plasma (PRP) to the scalp, topical minoxidil, and oral supplements for the promotion and support of hair growth. Efficacy was assessed with clinical assessment of AGA grade (Ludwig scale for female / Norwood-Hamilton scale for male) and with blind evaluation of hair quality in global photographs before and after treatment. Patients subjectively rated their satisfaction with the laser treatment on a scale from 0-3 and pain on a VAS scale from 0-10. RESULTS: AGA grade after treatment was lower compared to baseline (p = 0.015 and p = 0.125 in female and male patients, respectively). Blind evaluation indicated an improvement in hair quality in 93% of patients, either being described as much better (14%) or as better (79%), which was not correlated with age or AGA grade. The median satisfaction score was 3, and the median VAS score for pain was 2. The positive effect of the treatment on the hair quality is ongoing. No adverse reactions were reported. CONCLUSIONS: The treatment was effective in treating AGA, confirmed by a decrease in AGA grade and by blinded evaluation of global photographs. Although the possible additive or complementary effect of topical minoxidil or nutraceuticals cannot be excluded, our results suggest that the non-ablative Er:YAG laser SMOOTH™ mode as a monotherapy, or in combination with PRP, is an efficient and safe treatment for AGA-with a high satisfaction rate among patients regardless of patient age, AGA duration, or AGA stage.

Validated 5-point photonumeric scales for the assessment of the jowls and chin.

OBJECTIVE: The objective of this investigation was to create and to examine the reproducibility and validity of 5-point photonumeric assessment scales that allow objective assessment of chin retrusion and jawline sagging using a digital and a live validation. MATERIAL AND METHODS: Two new 5-point photonumeric scales created to assess chin projection and jawline sagging were validated by 12 experts in a digital validation and by 5 experts in a live validation setting. Intra-rater agreement and inter-rater agreement were assessed. RESULTS: For the digital validation, an almost perfect intra-rater (Kappa: 0.89 [95% CI: 0.86-0.91]) and almost perfect inter-rater agreement in both sessions (Kappa: 0.80 [95% CI: 0.74-0.86] and 0.80 [95% CI: 0.74-0.86]) was achieved for the Croma Chin Projection Assessment Scale, while intra-rater agreement (Kappa: 0.88 [95% CI: 0.85-0.91]) was almost perfect for the Croma Jawline Sagging Assessment Scale and inter-rater agreement being substantial in the first session (Kappa: 0.76 [95% CI: 0.71-0.81]) and almost perfect in the second session (Kappa: 0.81 [95%CI: 0.76-0.85]). For the live validation, intra-rater agreement was almost perfect for the Croma Chin Projection Assessment Scale (Kappa: 0.82 [95%CI: 0.74-0.90]) and the Croma Jawline Sagging Assessment Scale (Kappa: 0.83 [95%CI: 0.77-0.89]), while inter-rater agreement was substantial in both sessions for both scales. CONCLUSION: The created chin and jawline photonumeric grading scales are valid and reliable tools for assessing chin projection and jawline sagging. The scales will be of value for standardized chin evaluation and quantifying outcomes in clinical research and daily practice.

Validated 5-point photonumeric scales for the assessment of the periorbital region.

OBJECTIVE: The objective of this investigation was to create and validate 5-point photonumeric scales for the assessment of dynamic crow's feet, static crow's feet, and infraorbital hollows. MATERIAL AND METHODS: Three novel 5-point photonumeric scales were created by a medical team. A total of 12 raters from all over the world performed a digital validation, and a total of 5 raters a live validation of the created scale. RESULTS: The statistical analysis revealed almost perfect intra-rater and inter-rater reliability in the digital validation of the scales for the assessment of static and dynamic crow's feet as well as infraorbital hollows. In the live validation, both crow's feet scales showed almost perfect intra-rater reliability, while the Croma Infraorbital Hollow Assessment Scale showed substantial intra-rater reliability. Inter-rater reliability was substantial for all three scales in the live validation. All three scales, the Croma Dynamic Crow's Feet Assessment Scale, Croma Static Crow's Feet Assessment Scale, and Croma Infraorbital Hollow Assessment Scale, were validated digitally and in a live setting. CONCLUSION: The created scales to assess infraorbital hollowing, dynamic and static crow's feet have been shown to provide substantial to almost perfect agreement in the digital and live validation and can thus be considered as helpful tools in the clinical and research setting. While technical methods and appliances to assess the degrees of severity of age-dependent features are advancing, validated scales are of great importance due to their ease of use and, as shown by the validations, reliability, and reproducibility.

Hair regrowth and maintenance in alopecia universalis patient treated with nonablative Er:YAG laser.

Hair regrowth with no adverse effects following nonablative 2940-nm Er:YAG laser treatment in alopecia universalis patient resulted in high patient satisfaction and compliance. As the main challenge in alopecia universalis is maintenance of regrown hair, patient compliance associated with this treatment might represent an advantage over traditional treatment modalities.

The safety and efficacy of a cosmetic camouflaging agent for post-procedural bruising.

INTRODUCTION: A challenge of minimally invasive esthetic procedures (eg, injectables and threads) is managing adverse events (AEs), such as post-procedural bruising. Implementation of post-procedural camouflage therapy may minimize the appearance of bruising and mitigate AEs. AIMS: A physician and patient user experience program was designed to evaluate the safety and efficacy of a concealer for the cosmetic camouflage of post-procedural bruising. METHODS: Thirty female patients with a mean age of 42.03 years participated in the program. Physicians and patients completed various questionnaires regarding the safety and efficacy of the investigational product (Dermablend™ Professional Cover Care Full Coverage Concealer) at three timepoints: Visit 1 (Day 0); Visit 2 (Day 3); and Visit 3 (Day 14 ± 3 days). RESULTS: All patients presented with mild-to-moderate bruising following treatment with either esthetic injectables or threads. On average, users required 1.55 (SD: 0.72) coats to sufficiently cover their bruise(s). After application of the concealer, 78.18% of users displayed "clear skin with no signs of erythema" and 21.82% displayed "almost clear skin, with slight redness." No physician-reported AEs related to product use were reported throughout the evaluation period. No allergic reactions upon application nor intolerance to the product after prolonged use (ie, up to 14 days ± 3 days) was observed. Throughout the duration of use, 98.81% of subjects were at least slightly satisfied with results. At Visits 1 and 2, 100% of physicians were at least slightly satisfied with results. CONCLUSION: Cosmetic concealer use can ameliorate the post-procedural experience for patients presenting with mild-to-moderate bruising.

The role of a shelf-ready, human-derived, soft tissue injectable adipose matrix for facial volume correction.

BACKGROUND: Synthetic soft tissue fillers frequently used to restore facial volume do not provide a regenerative framework, limiting their sustained efficacy. Autologous fat transfer for facial rejuvenation supports tissue regeneration but has unpredictable outcomes depending on the quality of harvesting, processing, and implantation. AIMS: Exploration of the pros and cons of available tissue fillers and the role of an injectable Allograft Adipose Matrix (AAM) for facial rejuvenation. METHODS: The results of a literature review conducted by two clinicians with extensive experience in this field were discussed by a panel of dermatologists and surgeons who regularly treat patients with signs and symptoms of facial aging. A manuscript was prepared and reviewed by the panel taking into account the evidence and their clinical experience treating patients for facial rejuvenation. RESULTS: Facial rejuvenation needs to address the volume deficiency and repositioning of ptotic soft tissues. Frequently used synthetic fillers are suitable candidates for improving the facial appearance of fine lines and for molding. A better understanding of facial volume loss has allowed the use of adipose fat cells for facial rejuvenation. The injectable AAM is readily available and provides a regenerative framework for sustainable results. Prospective clinical and randomized studies support the effective and safe use of AAM for facial rejuvenation. CONCLUSION: AAM may offer an alternative to synthetic fillers and autologous fat implantation in the face without the cumbersome process of fat harvesting and processing. More robust studies are to confirm the positive results obtained in smaller studies using the soft tissue bio stimulatory injectable.

Tretinoin 0.05% Lotion for the Once-Daily Treatment of Moderate-to-Severe Acne Vulgaris: Impact of Gender and Race on Efficacy and Safety

Background: There has been an increasing interest in gender and racial differences both in the pathogenesis and treatment of acne vulgaris (acne), and postinflammatory hyperpigmentation (PIH) is a major concern in patients of color. Female acne patients report more anxiety and depression with acne improvement positively influencing Quality of Life (QoL) than their male counterparts, and there are differences in acne presentation. The first lotion formulation of tretinoin was developed using novel polymeric emulsion technology to provide an important alternative option to treat these acne patients, especially those who may be sensitive to the irritant effects of other tretinoin formulations. Objective: To determine the impact of gender and race on the efficacy and safety of tretinoin 0.05% lotion in treating moderate or severe acne. Methods: Post hoc analysis of 2 multicenter, randomized, double-blind, vehicle-controlled Phase 3 studies in moderate-to-severe acne. Subjects (aged 9 to 58 years, N=1640) were randomized (1:1) to receive tretinoin 0.05% lotion or vehicle, once-daily for 12 weeks. Efficacy assessments included changes in baseline inflammatory and noninflammatory lesions and treatment success (at least 2-grade reduction in Evaluator's Global Severity Score [EGSS] and clear/almost clear). Quality of Life was assessed using the validated Acne QoL scale. Safety, adverse events (AEs), cutaneous tolerability, and hypo-/hyper-pigmentation (using a 4-point scale where 0=none and 3=severe) were evaluated at each study visit. Results: At week 12, mean percent reduction in inflammatory lesion counts were 56.9% and 53.4% respectively in female and male patients compared with 47.1% and 39.4% with vehicle (P≤0.001), with females statistically significant to males at week 8 [P=0.026]). Mean percent reduction in noninflammatory lesion counts in females and males were 51.7% and 46.1% respectively, compared with 34.9% and 29.7% with vehicle (P<0.001), with females statistically significant to males at week 12 (P=0.035). Treatment success was achieved by 23.6% and 16.1% of female and male patients treated with tretinoin 0.05% lotion by week 12 (P≤0.001 vs vehicle) with females statistically significant compared with males (P=0.013). Significant differences in inflammatory lesion count reductions were reported in Caucasian patients from week 8, and Black African/American male patients at week 12. Only male patients reported significant differences in both races in terms of noninflammatory lesions, and only Caucasian patients reported significant differences in treatment success. Female patients treated with tretinoin 0.05% lotion had statistically significant improvements in each Acne QoL domain (except role-social) compared with vehicle. Improvements in QoL in male subjects were only statistically different for acne symptoms. Tretinoin 0.05% lotion was well-tolerated in both genders. There were more treatment-related AEs in the female subpopulation, with a significantly greater incidence of skin dryness (P=0.006), that was more common in the younger Caucasian females. Conclusions: Tretinoin 0.05% lotion has been shown to be effective and well tolerated in moderate-to-severe acne. Treatment was significantly more effective in females than males. Tretinoin 0.05% lotion was well tolerated by both genders, although there was a higher incidence of treatment-related AEs, especially skin dryness, in females. There were racial and gender differences in QoL and beneficial effects on PIH in those patients most at risk. J Drugs Dermatol. 2019;18(11):1128-1138.

Impact of Smoking and Alcohol Use on Facial Aging in Women: Results of a Large Multinational, Multiracial, Cross-sectional Survey.

Objective: Data on associations between facial aging and smoking or alcohol consumption are generally derived from small studies, and therefore, vary. The aim of this large multinational study was to determine more accurately which clinical signs of skin- and volume-related facial aging are associated with tobacco and alcohol use in women. Design: This was a subanalysis of a global, cross-sectional, Internet-based survey of self-reported facial aging. Participants: Women aged 18 to 75 years old (n=3,267) from the United States, Australia, Canada, and the United Kingdom who described themselves as white, Asian, black, or Hispanic were included. Measurements: Using a mirror, participants determined their own aging severity on photonumeric rating scales for 11 facial characteristics. Linear regressions were used to assess associations between each feature's severity and smoking status (never vs. current and former smoker); smoking pack years (0 versus 1-10, 11-20, and >20 years); alcohol use (none vs. moderate and heavy); and alcoholic beverage type, after controlling for body mass index, country, age, and race. Results: Smoking was associated with an increased severity of forehead, crow's feet, and glabellar lines; under-eye puffiness; tear-trough hollowing; nasolabial folds; oral commissures; perioral lines; and reduced lip fullness (p≤0.025) but not midface volume loss or visible blood vessels. Heavy alcohol use (≥8 drinks/week) was associated with increased upper facial lines, under-eye puffiness, oral commissures, midface volume loss, and blood vessels (p≤0.042). Conclusion: Smoking and alcohol consumption significantly but differentially impact skin and volume-related facial aging.

Consensus Recommendations on Adjunctive Topical Management of Atopic Dermatitis.

Atopic dermatitis (AD) is well-recognized as a very common chronic and relapsing pruritic skin disorder affecting both children and adults worldwide. The adverse effects on the quality of life of affected individuals and their families is well-established. The pathophysiology of AD is complex, leading to interindividual variations in clinical presentation and severity. The chronicity of AD, characterized by periods of exacerbation and remission, supports a strong need to develop measures that can effectively and safely prolong remissions between flares of the disease. This article provides an overview of AD including prevalence, severity, and disease course/progression, succinct summaries of pathophysiology and medical management, and discussion of epidermal barrier dysfunction and skin microbiome shifting associated with AD. Additional emphasis is placed on adjunctive topical skin barrier approaches that may prolong disease-free remissions. Results from a panel of dermatologists queried about adjunctive approaches to AD, using a modified-Delphi approach, are also discussed. J Drugs Dermatol. 2018;17(10):1070-1076.

Three-Dimensional Analysis of Minimally Invasive Vacuum-Assisted Subcision Treatment of Cellulite.

INTRODUCTION: This was a prospective non-randomized observational study of female subjects seeking treatment for cellulite who were consecutively enrolled into a registry. The objective was to evaluate the efficacy and safety of a tissue stabilized-guided subcision device for the treatment of cellulite using three-dimensional (3D) imaging analysis. METHODS: Subjects received a single treatment to the buttocks and/or posterolateral thighs with the study device. Follow-up telephone evaluations were conducted at 3 and 14 days to evaluate safety and 30 and 90 days to evaluate efficacy. Subjects returned to clinic at three months to obtain follow-up two dimensional and 3D imaging. RESULTS: Sixteen women of average age 44.1 years with a total of 291 lesions of cellulite were treated. Thirteen subjects presented for all follow up visits. Physicians graded results an average of 2.23/5 or "much improved" to "improved" with 9 subjects as much or very much improved (69.2%). Blinded assessors graded overall improvement an average of 2.8 (26-75% improvement) with 8 subjects having greater than 50% improvement overall (61.6%). Improvement in dimple depth was graded an average of 2.9, with 9 subjects having greater than 50% improvement (69.2%). Analysis of 3D imaging yielded 67.4% average improvement in negative volume and 58.4% improvement in minimum height of dimples. Most expected treatment effects resolved within three months after treatment. CONCLUSION: Utilizing three-dimensional imaging analysis, investigators quantitatively and objectively demonstrated efficacy of a tissue stabilized-guided subcision device in the treatment of cellulite of the buttocks and thighs.

Assessing the Potential Role for Topical Melatonin in an Antiaging Skin Regimen.

BACKGROUND: Melatonin is an endogenous hormone commonly associated with regulation of sleep. However, over the last two decades, research has elucidated a range of effects associated with the compound, including anti-inflammatory, both direct and indirect antioxidant activity, tissue regenerative benefits, and preservation of mitochondrial function. Melatonin's anti-inflammatory and antioxidant support, coupled with its mitochondrial support, make it an intriguing target for use to support skin health. Human skin and hair follicles express functional melatonin receptors. They also engage in substantial melatonin synthesis. By supporting cutaneous homeostasis, melatonin and its metabolites are thought to attenuate carcinogenesis and possibly other pathological processes, including hyperproliferative/inflammatory conditions. The primary extrinsic driver of aging has been considered to be exposure to ultraviolet (UV) light, which is well-established to contribute to sunburn, immunosuppression, skin aging, and carcinogenesis. Topically applied melatonin has been shown to reduce markers of reactive oxygen species formation and to reverse signs of skin aging. As the global population continues to age, photo-damage remains a significant cutaneous concern. While use of sunscreens and UV avoidance strategies are essential to mitigate skin cancer risks, the potential to protect the skin and improve the appearance of photo-damage through the use of topical antioxidant support is appealing. The evidence suggests that melatonin deserves consideration for topical use as an anti-aging and skin protective agent. It is shown to be both safe and effective when topically applied.

Consensus Recommendations for Combined Aesthetic Interventions Using Botulinum Toxin, Fillers, and Microfocused Ultrasound in the Neck, Décolletage, Hands, and Other Areas of the Body.

BACKGROUND: The popularity of aesthetic procedures in the face has led to greater disparity between treated areas and those that still show evidence of true age. Although many areas of the body often require multiple treatment procedures for optimal rejuvenation, combination therapy for specific areas is not yet well defined. OBJECTIVE: To develop recommendations for the optimal combination and ideal sequence of botulinum toxin (BoNT), hyaluronic acid, calcium hydroxylapatite (CaHA), and microfocused ultrasound with visualization in nonfacial areas across all skin phototypes. METHODS: Fifteen specialists convened under the guidance of a certified moderator. Consensus was defined as approval from 75% to 94% of all participants, whereas agreement of ≥95% denoted a strong consensus. RESULTS: Recommendations have been provided for the neck, décolletage, and hands and include the timing and sequence of specific procedures when used concurrently or over several treatment sessions. Position statements are offered in lieu of consensus for the upper arms, abdomen, buttocks, and knees. CONCLUSION: Nonfacial rejuvenation often requires multiple procedures for optimal results in individuals with significant age-related changes. Further clinical studies are recommended to raise awareness of non-facial indications and provide clinicians with the best evidence for best treatment practices.
