INDIVIDUAL ARTICLE: Skincare in Skin of Color: A Comprehensive Approach to Preprocedure, Intraprocedure, and Postprocedure.

Hyperpigmentation, uneven skin tone, textural changes, and dull skin are common cosmetic concerns in skin of color. Other signs of aging, including fine lines, deeper wrinkles, and skin laxity, also occur but may present in later decades. In-office procedures such as laser treatments, energy devices, toxins, fillers, and chemical peels are useful options for addressing the most common cosmetic concerns in skin of color patients. Skincare can play an important role in improving cosmetic outcomes when used in conjunction with in-office procedures. With the availability of these approaches, clinicians can now integrate in-office procedures with skincare strategies to offer patients with skin of color a comprehensive treatment plan that meets their needs.

Patient satisfaction following treatment with micro-focused ultrasound with visualization: A retrospective cross-sectional study.

BACKGROUND: There has been increased public interest in noninvasive skin tightening procedures that produce the best possible cosmetic outcomes. Micro-focused ultrasound with visualization (MFU-V) is a secure, efficient method of treating skin laxity approved by the FDA. Few studies have assessed patient satisfaction following MFU-V. MATERIALS AND METHODS: A retrospective cross-sectional study was conducted between January 2022 and 2023. After obtaining the author's permission, a previously examined and published questionnaire was used to contact all participants (n = 98) who had received MFU-V therapy in a private clinic in Riyadh, Saudi Arabia, between 2016 and 2020 via phone interview. RESULTS: All 98 patients undergoing MFU-V were female. About two-thirds indicated they were satisfied or very satisfied with the results. Those receiving treatment around the eye and submentum reported lower satisfaction levels than those receiving therapy in other regions. The number of treatment locations and satisfaction were positively correlated. Patients treated by consultants rather than laser experts reported much higher satisfaction levels. Satisfaction and the amount of time for improvement to occur following treatment were correlated statistically. Pain and tingling were the most frequent adverse effects the respondents reported, followed by skin redness and swelling; however, adverse effects were not connected with satisfaction. Cost (78.6%) was cited as the main deterrent to seeking treatment again. CONCLUSION: MFU-V, an FDA-approved procedure, has proven effective and safe for treating facial and neck skin laxity. When patients are carefully selected and physicians properly trained, higher satisfaction is achieved.

Enhancing Facial Filler Training with 3D-Printed Models: A Prospective Observational Study on Medical Student Competence.

BACKGROUND This study evaluated the efficacy of 3-dimensional (3D) printed facial models in training medical students for cosmetic facial filler applications. A prospective observational study included 40 medical faculty students without prior filler application or surgical training. They received theoretical and practical training using 3D-printed face models, assessed through pre- and post-training surveys. MATERIAL AND METHODS Facial models were designed using SolidWorks and printed with a Mars 2 PRO 3D printer using PLA filament and high-performance silicone. Training comprised in-class instruction, live demonstrations, hands-on practice, and individual guidance. Students' skills were assessed through self-assessments and objective criteria. RESULTS After training, students showed significant improvement in procedural understanding and application locations, with increased confidence and competence (P<0.001). Statistical analysis confirmed these improvements. CONCLUSIONS 3D-printed facial models are valuable for enhancing medical students' skills in cosmetic facial fillers, offering cost-effective and safe simulation. This approach improves practical skills and confidence, benefiting medical education and patient care.

Polynucleotides in Aesthetic Medicine: A Review of Current Practices and Perceived Effectiveness.

Polynucleotides, complex molecules composed of nucleotides, have gained attention in aesthetic medicine for their potential to regulate gene expression and promote tissue regeneration. This review aims to provide an overview of the current practices and perceived effectiveness of polynucleotides in aesthetic medicine. A comprehensive search of the literature was conducted using keywords related to polynucleotides, cosmetic application, and aesthetic application. Studies were selected based on their relevance to aesthetic medicine and the inclusion of human subjects. The review found that polynucleotides have been used to improve skin texture, reduce wrinkle depth, and enhance facial appearance. The studies reported varying degrees of efficacy and safety, with some studies demonstrating significant improvements in skin elasticity and hydration. However, others reported limited or no benefits. The review also highlighted the need for further research to establish the optimal use and efficacy of polynucleotides in aesthetic medicine. While the existing literature suggests that polynucleotides may have potential benefits in aesthetic medicine, more research is needed to fully understand their mechanisms of action and optimal use. Clinicians should be aware of the current limitations and potential risks associated with the use of polynucleotides in aesthetic medicine.

Outstanding user reported satisfaction for light emitting diodes under-eye rejuvenation.

The under-eye region is an area of significant cosmetic concern. Photobiomodulation (PBM) has emerged as an effective, safe, inexpensive, and convenient treatment for skin rejuvenation. Herein, we aim to evaluate the safety and efficacy of a LED under-eye device for under-eye rejuvenation, as measured by objective and patient reported outcomes. Eleven participants self-administered treatment using a commercially available LED device emitting red (633 nm) and near infrared (830 nm) light for six weeks. Standardized photographs and questionnaires were administered at baseline and six weeks. Photographic digital analysis indicated an improvement in under-eye wrinkles at six weeks compared to baseline, with a reduction in wrinkle score from 20.05 to 19.72. However, this finding was not statistically significant. Participants self-reported consistent improvements in under-eye wrinkles, texture, dark circles, bags, pigmentation, and erythema. All participants reported a high degree of comfortability, ease of use, and satisfaction with the eye device. The participants noted no moderate or severe adverse events and few reports of transient expected outcomes such as mild erythema. The participants' self-reported improvements and high user satisfaction, and the device's favorable safety profile, highlights the benefits of at-home LED devices for under-eye rejuvenation. Future randomized controlled trials with larger sample sizes could further establish the safety and efficacy of at-home LED under-eye treatments.

A 52-week follow-up, multi-center, randomized, double-blinded comparison of efficacy and safety of two hyaluronic acid fillers for the treatment of moderate-to-severe nasolabial folds in Chinese population.

INTRODUCTION: To investigate the efficacy and safety of Cutegel® MAX (Cutegel) in the correction of moderate-to-severe nasolabial folds (NLFS) compared to Restylane® (Restylane, control). METHODS: This study was a 52-week, multicenter, randomized, double-blinded, active-controlled clinical trial. Qualified participants with moderate-to-severe NLFs were randomly assigned in a 1:1 ratio to receive Cutegel or Restylane. For the primary efficacy endpoint, the response rate was defined as the percentage of subjects exhibiting an improvement of at least one-point based on blinded evaluation of Wrinkle Severity Rating Scale (WSRS) at 24 weeks after injection. Other secondary efficacy endpoints and treatment-emergent adverse events (TEAEs) were assessed. RESULTS: Of 340 subjects randomized, 317 completed the week 52 visit. In the per protocol set (PPS), the blinded evaluator-assessed response rates at week 24 were 81.17% for Cutegel versus 77.56% for Restylane (p = 0.327). The between-group treatment differences in response rates were 3.60% [95% confidence interval (CI) = (-5.39%, 12.60%)], which demonstrated the noninferiority of Cutegel. Other secondary efficacy endpoints supported this. No significant differences were observed in the occurrence of adverse events between the two groups. CONCLUSION: Similar to Restylane, Cutegel was effective and well tolerated in correcting moderate-to-severe NLFs among the Chinese population.

Nasolabial folds (NLFs) are among the early indicators of facial aging process. In the past, rhytidectomy has been considered a safe procedure, yet it continues to carry risks such as hematoma, skin necrosis, nerve injury, and infection. With the ongoing development of biomaterials including hyaluronic acid (HA), minimally invasive injection procedures for the aesthetic correction of NLFs have become the preferred choice in recent years. The widespread use of HA has resulted in the development of various types of commercial HA fillers, such as Cutegel and Restylane. It is well known that HA filler products produce varying effects, attributable to differences in their components and physical properties. Previous studies have established that Restylane is a safe and effective HA dermal filler for the correction of NLFs. However, there is a lack of studies on both the cosmetic results and safety data for Cutegel in the published literature. Therefore, a randomized, double-blinded, active-controlled clinical trial was conducted at seven Chinese hospitals to evaluate the efficacy and safety of Cutegel for the correction of moderate-to-severe NLFs, compared to the approved Restylane in China. Among the 340 randomized subjects, 170 subjects received Cutegel, and 169 subjects received Restylane. Both groups reported similar improvements in WSRS (the between-group treatment differences in response rates exceeded the prespecified noninferiority margins), and also in other efficacy evaluations. Additionally, the two treatment groups showed similar safety profiles. In summary, Cutegel proved to be well tolerated and effective in this randomized, active-controlled clinical study, demonstrating its noninferiority to Restylane and validating its use as an alternative treatment for Chinese subjects with moderate-to-severe NLFs.

A Prospective, Multicenter, Evaluator-Blinded, Randomized Study of Diluted Calcium Hydroxylapatite to Treat Decollete Wrinkles.

BACKGROUND: Calcium hydroxylapatite (CaHA) dermal filler is used for a variety of aesthetic treatments; however, the safety and effectiveness of diluted CaHA for the treatment of décolleté wrinkles have not been established. OBJECTIVE: To demonstrate the effectiveness and safety of diluted CaHA (Radiesse; 1:2 CaHA:saline) injection for the improvement of décolleté wrinkles in females. METHODS: Eligible females with moderate or severe ratings on the Merz Aesthetic Scale (MAS) Decollete Wrinkles - At Rest received up to 3 injection cycles of diluted CaHA either 8 weeks apart (3 injection cycles) or 16 weeks apart (2 injection cycles). Effectiveness was evaluated by improvement on the MAS. Adverse events were recorded over a 52 week period. RESULTS: Sixteen weeks after the last treatment, the response rate (1-point improvement or greater) on the MAS Decollete Wrinkles - At Rest was 73.5% (P<0.0001; pooled sample) for all patients. The use of diluted CaHA in the decollete also demonstrated a favorable safety profile. CONCLUSIONS: Diluted CaHA is a safe and effective treatment for the improvement of decollete wrinkles in females.J Drugs Dermatol. 2024;23(7):551-556.  doi:10.36849/JDD.8261.

Intracorporeal evaluation of hyaluronic acid fillers with varied rheological properties and correlations with aesthetic outcomes.

BACKGROUND: Understanding the differences in soft tissue filler rheology and how these properties can impact clinical results is a fundamental concepts for any injector. This study aimed to assess the tissue integration characteristics of hyaluronic acid (HA) fillers manufactured with different technologies (Non-Animal Stabilized HA [HA-N] or Optimal Balance Technology [HA-O]) using ultra-high-frequency ultrasound. METHODS: Twelve female participants with mild-to-moderate midface volume loss and temporal hollowing were enrolled and treated with HA-N and/or HA-O. Participants were seen at five visits (screening/baseline [treatment], and Weeks 1 [optional touch-up], 4, 6, and 8 [follow-up visits]). Ultrasound was used to evaluate the degree of product integration. RESULTS: On ultrasound, HA-N presented with distinct borders, minimal tissue integration, and a capacity to displace tissues. Conversely, HA-O tended to spread horizontally within the same tissue plane and integrated within tissues. The volumizing capacity of the HA-O fillers was dependent on particle size. CONCLUSION: HA-N is suited for deep injections in areas such as the upper lateral cheek and under the muscle of the temporal region when a lifting effect is desired; HA-O is best suited for subcutaneous injections, in areas of dynamic movement or for patients with thin skin; and can be injected subcutaneously or supraperiosteally when a volumizing effect is desired.

Improved brachial skin hydration and appearance with hyperdiluted calcium hydroxylapatite.

INTRODUCTION: The search for minimally invasive treatments for areas not covered by clothing, such as the arms, has increased, particularly to combat flaccidity resulting from factors such as aging and weight loss. This study evaluated the efficacy of calcium hydroxyapatite (CaHA), an injectable biostimulator, in improving flaccidity and hydration of the skin of the arms. MATERIALS AND METHODS: Six women between 40 and 50 years old with visible signs of brachial flaccidity were selected. Calcium hydroxyapatite was injected into the arms in a 1:4 dilution (1.5 mL per side), with subjective evaluation based on the GAIS score and objective hydration analysis using corneometry. RESULTS: After a single application of CaHA, there was a significant increase in skin hydration (12.2%), objectively assessed by corneometry. Patient and physician satisfaction was high, evidenced by visible improvements in photographs and by the GAIS score. No significant adverse events were reported, demonstrating the safety of the procedure. DISCUSSION: Our clinical observations confirm the ability of CaHA to visibly improve arm flaccidity. In addition, hydration measures support previous histological studies demonstrating increases in dermal proteoglycans. Compared to other studies, the increase in skin hydration with CaHA was similar to those obtained with hyaluronic acid, suggesting comparable results with a more comfortable and less invasive technique. CONCLUSION: This study demonstrates the efficacy of CaHA in improving hydration of brachial skin after a single treatment. Despite the limitations of the sample size, the research contributes to the medical literature, highlighting the utility of the 3 mL CaHA presentation for brachial treatment with objective results in skin hydration.

Profhilo® Structura, Current Status and Future Perspectives: A Practical Review.

Hyaluronic acid (HA)-based injectables continue to grow in popularity and are used worldwide to improve facial changes associated with aging. Profhilo® Structura (IBSA Farmaceutici Italia, Lodi, Italy) is a novel HA-based product that uses nano hybrid complex of hyaluronic acid (NAHYCO)® technology to create hybrid cooperative complexes consisting of high and low molecular weight HA. Profhilo® Structura's high concentration (45 mg of total HA) and rheological properties (ie, viscosity [resistance to flow] and elasticity [stickiness]) have been specially formulated to restore facial adipose tissue. Because of their early involvement in the facial aging process, the superficial medial and lateral-temporal cheek fat compartments are good candidates for treatment. However, recommendations and guidelines are necessary to ensure that treatment is safe and effective. Three experts were invited to IBSA Farmaceutici Italia Srl to discuss clinical rationale, optimal injection techniques, and clinical outcomes for treating the superficial medial and lateral-temporal cheek fat compartments with Profhilo® Structura. These techniques were developed using patients presenting with either initial hypotrophy of fat compartments within the preauricular area (ie, sinkers) or jowl sagging due to hypotrophy within the preauricular and zygomatic areas (ie, saggers). Targeting these areas using the optimal injection site can maximize product diffusion and minimize the risk for vascular compromise. Targeting these areas also leads to lateral tightening and lipolifting effects due to adipose tissue restoration. The experts agreed that Profhilo® Structura is currently the first and only HA-based injectable treatment that can integrate and restore the adipose tissue in these affected fat compartments.

Efficacy and safety of a novel monopolar radiofrequency device with a continuous water-cooling system in patients with age-related facial volume loss.

BACKGROUND: Esthetic radiofrequency (RF) technology has much attracted public attention with the increasing demand for skin rejuvenation. A continuous water cooling-based monopolar RF (MRF) device was designed for the first time to protect the epidermis and maximize clinical outcomes. OBJECTIVE: Assess the efficacy and safety of the proposed MRF device in patients with mild-to-moderate sunken cheeks and jawline laxity. METHODS: Twenty-one patients underwent a single session of MRF treatment. Quantitative analysis was performed using a 3D imaging technique. Postprocedural clinical improvements were assessed with the Merz Scale. Regarding safety, adverse events (AEs), thermal sensation (TS) and pain intensity were explored. Patient satisfaction was surveyed with the Self-Assessment Questionnaire (SAQ). RESULTS: The follow-up investigation demonstrated that facial volume increased across the cheek and jawline, with lifting effects throughout the treatment area. The Merz Scale assessment revealed that sunken cheeks, sagging jawlines and wrinkles were markedly improved. In addition, there were transient AEs, mild TS and moderate pain. In SAQ, 81% patients were satisfied with the procedure. CONCLUSIONS: This study provided quantitative evidence for postprocedural volumetric increases along with enhanced lifting effects, strongly implying that the proposed MRF device can be an attractive option for improving facial skin volume loss and laxity.

Performance and Safety of Amino-Acid- and Hydroxyapatite Enriched-Hyaluronic Acid Intradermal Gel in Facial Skin Defects.

Background and Objectives: The facial skin defects associated with aging are common concerns in the aging population. Hyaluronic-acid-based intradermal gels have established themselves as safe and effective treatments for addressing these concerns. Recently developed enriched products aim to enhance the efficacy of these gels, yet their effectiveness lacks thorough validation in the existing literature. Materials and Methods: In this retrospective analysis, we investigated the outcomes of intradermal gel treatments in 103 patients with soft tissue defects. This study included three groups: 35 patients received amino-acid-enriched hyaluronic acid gel, another 35 were treated with hydroxyapatite-enriched hyaluronic acid gel, and the remaining 33 underwent hyaluronic acid treatment only. The efficacy of the treatments was assessed using the Global Aesthetic Improvement Scale (GAIS) score, while patient satisfaction was gauged through a detailed questionnaire. Any adverse event was monitored. Results: The treatments demonstrated remarkable efficacy, as evidenced by mean GAIS scores of 1.714 points for those treated with amino acid-enriched hyaluronic acid gel, 1.886 points for individuals receiving hydroxyapatite-enriched hyaluronic acid gel, and 1.697 for those treated with hyaluronic acid alone, all showing statistical significance (p < 0.0001). Patient satisfaction was very high. Significantly, there were no recorded instances of major adverse events. Conclusions: Hyaluronic gels, particularly those enriched with amino acids and hydroxyapatite, are effective and safe interventions for addressing facial skin aging defects. They serve as valuable tools in mitigating age-related blemishes and contribute to the overall improvement of skin aesthetics.
