A Practical Algorithm Integrating Skin Care With Nonenergy and Injectable Dermatologic Procedures to Improve Patient Outcomes and Satisfaction.

BACKGROUND: The most rapidly increasing medical aesthetic procedures for facial antiaging comprise nonenergy and injectable treatments. Currently, standards for skin care before, during, and after nonenergy and injectable treatments are lacking. The algorithm on supportive skin care for facial antiaging nonenergy and injectable treatments aims to stimulate healing, reduce downtime, and improve comfort and treatment outcomes.  Methods: A panel of 7 global physicians employed a modified Delphi method and reached a consensus on an algorithm for supportive skin care for nonenergy and injectable antiaging treatments based on the best available evidence and the panel members’ clinical experiences and opinions. RESULTS: The algorithm has a pretreatment (starts 2 – 4 weeks before the procedure) and treatment or ongoing (day of treatment) section, followed by care after the procedure (0 – 7 days) and follow-up care (1 – 4 weeks after the procedure). Applying a broad-spectrum sunscreen with an SPF 30 or higher, combined with protective measures, such as wearing a wide-brimmed hat and sunglasses, is recommended to protect the face from sun exposure. Dyschromia is a significant concern for those with richly pigmented skin. Clinicians may recommend skin care using a gentle cleanser and moisturizer containing vitamins C and E, retinoid, or other ingredients, such as niacinamide, kojic acid, licorice root extract, azelaic acid, and tranexamic acid, depending on the patient's facial skin condition. CONCLUSION: Nonenergy and injectable procedures combined with skin care or topical treatments may improve outcomes and patient satisfaction. Topical antioxidants and free radical quenchers can combat photodamage and may offer a safe alternative to topical hydroquinone.    J Drugs Dermatol. 2024;23(4):     doi:10.36849/JDD.7918.

Decoding the Implications of Glucagon-Like Peptide-1 Receptor Agonists on Accelerated Facial and Skin Aging.

Following the advent of glucagon-like peptide-1 receptor agonists (GLP1RA), subsequent unintended effects such as accelerated facial aging and altered skin health have been noted. This review delves deeper into the causative underlying mechanisms and provides insights into the intricate relationship between GLP-1RA, adipose tissue, and premature facial aging, thereby highlighting the need for a nuanced understanding of their effects on facial alterations and skin health. Studies exploring the potential effects of GLP-1RA on facial alterations and offering insights into the possible underlying mechanisms, causes and clinical implications were included. The accelerated facial aging and altered skin health observed in GLP-1RA patients appears to be multifactorial, involving loss of dermal and subcutaneous white adipose tissue, altered proliferation and differentiation of adipose-derived stem cells (ADSCs), and impacts on the production and secretion of hormonal and metabolic factors. These changes compromise the structural integrity and barrier function of the skin and may lead to diminished facial muscle mass, further exacerbating the appearance of aging. The insights presented call for a paradigm shift in the clinical management of facial changes induced by GLP-1RA, with a focus on treatment strategies aimed at targeting ADSC stimulation. These include autologous fat transfers to reintroduce cells rich in ADSCs for rejuvenation, composite fat grafting combining autologous fat with/without stromal vascular fraction, and the strategic use of soft tissue fillers for volume restoration and biostimulation. This review highlights the potential role of GLP-1RA in modulating adipose tissue dynamics, contributing to accelerated aging through metabolic, structural, and hormonal pathways.

Microtoxin for Improving Pore Size, Skin Laxity, Sebum Control, and Scars: A Roundtable on Integrating Intradermal Botulinum Toxin Type A Microdoses Into Clinical Practice.

BACKGROUND: In aesthetic clinical practice, botulinum toxin type A (BoNT-A) is best known for its use as a neuromodulator for the treatment of dynamic facial lines; however, when injected intradermally as microdroplets, BoNT-A can improve skin quality and overall skin appearance. OBJECTIVES: To discuss key aspects of microtoxin use in clinical practice and provide expert guidance on utilization. METHODS: As part of a continuing medical education lecture series and roundtable, the authors discussed key aspects of microtoxin patient selection, injection technique, and safety. RESULTS: The experiences of expert faculty are shared here. Clinical experience is consistent with reported data. Microtoxin can be used to reduce pore size, sebum production, rosacea, acne, and fine lines, and to improve jawline and neck definition. Intradermal injection can also be employed for the improvement of transverse neck lines as well as for the safe prevention and management of scars and keloids. CONCLUSIONS: Expanding the use of BoNT-A, a predictable, minimally invasive, and affordable treatment to address commonly encountered complaints is appealing. The authors have found that making patients aware of microtoxin as a treatment option results in an increased interest in and utilization of BoNT-A, and high satisfaction among appropriately selected patients.

The unsightly appearance of cellulite leads many affected individuals to seek treatment by trained specialists. The objective of this review is to provide the reader with an update on new and innovative therapies for cellulite including various treatment combinations to maximize therapeutic outcomes, and strategies for minimizing adverse events. The availability of new technologies and the results from recent clinical trials provide additional tools and data to consider when creating treatment plans for cellulite patients. This update to previous treatment recommendations is based on the most recent developments in cellulite management including the personal experiences of the authors with an emphasis on injectable enzymes, acoustic subcision, targeted verifiable subcision, and biostimulators. Formal clinical studies are warranted to compare various treatment modalities and further investigate combination regimens.

Validated Assessment Scales for Cellulite Dimples on the Buttocks and Thighs in Female Patients.

BACKGROUND: New treatment methods for cellulite require globally accepted scales for aesthetic research and patient evaluation. OBJECTIVE: To develop a set of grading scales for objective assessment of cellulite dimples on female buttocks and thighs and assess their reliability and validity. MATERIALS AND METHODS: Two photonumeric grading scales were created and validated for dimples in the buttocks in female patients: Cellulite Dimples-At Rest, and Cellulite Dimples-Dynamic. Sixteen aesthetic experts rated photographs of 50 women in 2 validation sessions. Responses were analyzed to assess inter-rater and intra-rater reliability. RESULTS: Overall inter-rater reliability and intra-rater reliability were both "almost perfect" (≥0.81, intraclass correlation efficient and weighted kappa) for the At Rest scale. For the Dynamic scale, inter-rater reliability and intra-rater reliability were "substantial" (0.61-0.80). There was a high correlation between the cellulite scales and body mass index, age, weight, and skin laxity assessments. CONCLUSION: Consistent outcomes between raters and by individual raters at 2 time points confirm the reliability of the cellulite dimple grading scales for buttocks and thighs in female patients and suggest they will be a valuable tool for use in research and clinical practice.

Validated Assessment Scales for Skin Laxity on the Posterior Thighs, Buttocks, Anterior Thighs, and Knees in Female Patients.

BACKGROUND: The demand for noninvasive skin-tightening body procedures is increasing. OBJECTIVE: To develop a set of grading scales for the objective assessment of skin laxity and assess their reliability and validity. MATERIALS AND METHODS: Two photonumeric grading scales were created and validated for skin laxity in female patients: Skin Laxity-Posterior Thighs/Buttocks, and Anterior Thighs/Knees. Fifteen aesthetic experts rated photographs of 50 women in 2 validation sessions. Responses were analyzed to assess inter-rater and intra-rater reliability. RESULTS: Overall inter-rater reliability according to intraclass correlation efficient (ICC) 2.1 and weighted kappa was at least "substantial" for both scales in both sessions, and "almost perfect" (≥0.81) for the Anterior Thighs and Knees scale in session 2. Intra-rater reliability was "almost perfect" for both scales (ICC 2.1) and "substantial" to "almost perfect" by weighted kappa. A correlation between the skin laxity scales and body mass index, age, weight, sun exposure, and cellulite severity was observed. CONCLUSION: The skin laxity photonumeric grading scales are valid and reliable instruments for assessing laxity on the posterior thighs and buttocks, and anterior thighs and knees. The scales will be of value for standardizing clinical evaluations and quantifying outcome measurements in research and clinical practice.

Validation of a Photonumeric Assessment Scale for Grading the Slope of the Asian Forehead.

BACKGROUND: As the number of aesthetic treatments has grown, so have the number of photonumeric assessment scales used to compare the effectiveness of these aesthetic treatments in specific anatomical areas; however, these are primarily based on Caucasian features. OBJECTIVE: To assess the validity of the first aesthetic scale for assessing the slope of the Asian forehead. A secondary objective was to correlate this scale with subject demographics and baseline characteristics. METHODS: During 2 validation sessions, 13 raters assessed full frontal and lateral facial images of female (n = 28; 56.0%) and male (n = 22; 44%) subjects. For each subject, the severity of forehead sloping was graded from 0 (convex forehead, optimal forehead volume) to 4 (concave forehead, very severe sloping). Raters also assessed the age of each subject and the estimated aesthetic treatment effort required to treat each subject. RESULTS: Inter-rater reliability was "substantial" with scores of 0.67 and 0.68 for the first and second validation sessions, indicating high reliability. BMI showed the highest correlation with the scale and was a significant predictor in the final regression model. CONCLUSION: This photonumeric assessment scale will be useful for assessing the slope of the Asian forehead in both clinical and research settings.

The Safety and Efficacy of Treatment With a 1,927-nm Diode Laser With and Without Topical Hydroquinone for Facial Hyperpigmentation and Melasma in Darker Skin Types.

BACKGROUND: The nonablative, fractional, 1,927-nm diode laser is theoretically a safe and effective treatment for hyperpigmentation and melasma in darker skin and may potentiate topical cosmeceutical delivery. OBJECTIVE: To evaluate the use of a nonablative, fractional, 1,927-nm diode laser with and without topical 2% hydroquinone (HQ) cream for moderate-to-severe facial hyperpigmentation in Fitzpatrick skin Types III-V. METHODS: Forty adults underwent 4 laser treatments at 2-week intervals and were randomized to daily application of 2% HQ cream or moisturizer. Follow-ups were conducted 4 and 12 weeks after the final laser treatment. RESULTS: Hydroquinone and moisturizer groups demonstrated Mottled Pigmentation Area and Severity Index improvements of approximately 50% at post-treatment Weeks 4 and 12. Blinded investigator-assessed hyperpigmentation and photodamage improved significantly for both the groups at post-treatment Weeks 4 and 12. Subject satisfaction improved significantly in both the groups by post-treatment Week 4. Although investigator-rated Global Aesthetic Improvement Scale scores were significantly better in the HQ group at post-treatment Week 12, satisfaction was higher among those using moisturizer. No adverse events were noted. CONCLUSION: The nonablative, fractional, 1,927-nm diode laser produced significant improvement in hyperpigmentation in Fitzpatrick skin Types III-V by 4 weeks, with maintenance of results at 12 weeks after treatment even without HQ.

Global Consensus Guidelines for the Injection of Diluted and Hyperdiluted Calcium Hydroxylapatite for Skin Tightening.

BACKGROUND: Calcium hydroxylapatite (CaHA) is approved to correct moderate-to-severe wrinkles and folds and soft-tissue volume loss in the face and hands. More recently, subdermal injection using diluted CaHA has been used to improve skin laxity. OBJECTIVE: To review evidence for the safe and effective use of diluted CaHA in the face and body and provide best practice recommendations. METHODS: A global panel of expert aesthetic physicians convened to develop consensus-based guidelines for treating laxity and superficial wrinkles using diluted (ratio of 1:1) and hyperdiluted (≥1:2) CaHA. RESULTS: Diluted and hyperdiluted CaHA stimulates targeted neocollagenesis in the injection area to improve laxity and skin quality in the mid- and lower face, neck, décolletage, upper arms, abdomen, upper legs, and buttocks. Treatment can be used as an adjunct to volume augmentation or combined with additional modalities for optimal results. Adverse events are related to the injection and include bruising, swelling, mild pain, and induration. In thinner and darker skin, too-superficial injections of less diluted CaHA can lead to more adverse events. CONCLUSION: This report provides preliminary guidelines for the novel off-label use of CaHA for biostimulation in the face and body. Further trials will provide additional clarity regarding treatment paradigms for optimal outcomes.

Treating the Young Aesthetic Patient: Evidence-Based Recommendations.

BACKGROUND: There is growing demand for cosmetic treatments in the younger population, yet counseling and treating this age group can be difficult to justify.

OBJECTIVE: Chronologic changes that cause noticeable signs of aging are discussed within each age group. Age-appropriate cosmetic preventions and interventions are therefore recommended.

METHODS: A PubMed search was performed for high quality trials and evidence based reviews on the basic science of aging, as well as on cosmetic modalities and their histological, biochemical, and clinical effects.

RESULTS AND CONCLUSIONS: Specific age-related changes occur with each decade of life. A complete understanding of when these physiologic changes occur helps determine age-appropriate cosmetic counseling, preventions, and interventions.

First Consensus on Primary Prevention and Early Intervention in Aesthetic Medicine.

BACKGROUND: Facial aging is a complex interplay of extrinsic and intrinsic factors leading to progressive changes in the skin, subcutaneous tissue, and bone. Clinical experience suggests that early aesthetic intervention may slow the signs of aging, but treatment in the absence of symptoms or with minimal signs of aging has not yet been properly addressed. OBJECTIVES: To provide treatment recommendations for primary prevention and early intervention in individuals with no or minimal signs of aging. METHODS: Fourteen specialists in aesthetic medicine convened over a full-day meeting under the guidance of a certified moderator. RESULTS: Tailored treatment recommendations have been provided for prevention and early intervention of fine wrinkles, static lines and folds, irregular pigmentation, laxity, and subcutaneous volume loss by protecting the epidermis, stimulating neocollagenesis, reducing hyperkinetic musculature, and reinforcing supporting structures. CONCLUSION: Preventive measures and early therapeutic interventions that may alter the course of facial aging were defined. Further studies are needed to support these recommendations with the best possible evidence.

Communication Concepts for Prevention and Early Intervention in Aesthetic Medicine: Consensus and Literature Review.

BACKGROUND: Communication concepts relating to prevention and early intervention (P&E) within aesthetic medicine are poorly understood and highly underexplored. However, effective communication is a key criterion for successful outcomes. OBJECTIVES: To introduce the framework for P&E communication strategies within a younger population and explore the barriers that may be encountered. METHODS: A literature review on P&E communication strategies in aesthetic medicine and related topics of interest was conducted and used to construct a working framework that may be applied in clinical practice. RESULTS: Examination of existing literature revealed a need for a more structured communication framework for P&E encompassing up-to-date evidence-based learning and educational marketing that is tailored to individual needs and target populations. Message framing-the way in which a message is presented-is an important consideration in the dissemination of information to promote changes in health behaviour. A structured consultation is key to optimising patient engagement and ensures a tailored approach to understanding and catering to the specific needs of each patient. CONCLUSION: This is the first paper to discuss the communication concepts behind P&E within aesthetic medicine and paves the way for further research and focus in this significant field.

Neck Rejuvenation Using a Combination Approach: Our Experience and a Review of the Literature.

BACKGROUND: Aging of the neck is characterized by changes that include skin dyspigmentation, laxity, rhytides, loss of the mandibular contour, widening of the cervicomental angle, accumulation of submental fat, volume loss and prominence of the platysmal bands. Many cosmetic options exist to address these changes individually, but little literature exists about the safety and efficacy of combining such procedures and devices. OBJECTIVE: To review the existing literature and the authors' experience in safely and effectively combining aesthetic rejuvenation modalities for the neck. METHODS: A Medline search was performed on combination treatments for neck rejuvenation, and results are summarized. Practical applications for combining these procedures are discussed. RESULTS: Studies examining the efficacy and safety of intense pulsed light, ablative fractional lasers, nonablative fractional lasers, microfocused ultrasound with visualization, thermistor-controlled subsurface monopolar radiofrequency, cryolipolysis, ATX-101, liposuction, laser lipolysis, neuromodulators, and hyaluronic acid dermal fillers in the neck were found. The authors review their experience in combining these techniques. CONCLUSION: Review of the literature revealed options for non- and minimally-invasive rejuvenation of the skin and volume restoration of the neck, but little literature was found on the safety and efficacy of combining such procedures. The authors' experience in clinical practice is that many neck rejuvenation techniques can be combined safely. A combination approach often produces the most optimal outcome for the patient seeking neck rejuvenation.

Combination therapy in skin of color including injectables, laser, and light devices.

With the rapid increase in patients seeking cosmetic treatments, the variation in responses of lightly pigmented skin versus darkly pigmented skin has become increasingly apparent. Despite extensive treatment options in patients with skin of color, there is a paucity of well-designed studies performed on this patient population. The lack of research is concerning, as it is well documented that patients with darker skin types are at an increased risk of adverse events when treated with many of the available modalities used in cosmetic procedures. Fortunately, by combining a variety of treatments, these risks may be abrogated, and combination treatments may be a promising regimen for a wide variety of cosmetic complaints. An overview and evaluation of the research of combination therapy in skin of color is presented.

Clinical Efficacy and Safety of a Monopolar Radiofrequency Device With Comfort Pulse Technology for the Treatment of Facial and Neck Laxity in Men.

The objective of this study was to demonstrate the efficacy and safety of a monopolar radiofrequency treatment for facial and neck laxity in men. Twelve men received one treatment of the face and upper portion of the neck using an RF system with comfort pulsed technology. Standardized photographs were taken at baseline and at 1, 3, and 6 months of follow-up. Study investigators evaluated facial and neck laxity at baseline and all follow-up visits using the Fasil Laxity Scale. Patents and investigators assessed skin texture and overall appearance using the Quartile Improvement Scale. Average improvement in treated areas was statistically significant at 1-month (P<.01), 3-month (P=.02), and 6-month (P=.05) follow-up visits compared with baseline. Investigators rated greatest improvement in skin texture and overall appearance (mild to moderate) at the 3-month follow-up. Patient assessments demonstrated moderate improvement in skin laxity, skin texture, and overall appearance maintained out to 6 months after treatment. A total of 64% of patients were satisfied to very satisfied with treatment at the 6-month follow-up. One RF treatment of the face and neck yielded 20% reduction in facial laxity 1 month after treatment, with maintained improvement out to 6 months (15% reduction).
