RESUMO

BACKGROUND: Medical aesthetic procedures for facial rejuvenation with laser and energy-based devices (EBDs) are rapidly increasing. The following cases highlight real-life experience using a multi-modality system with various handpieces that combine intense pulsed light (IPL), laser hair removal (808 diode), high-intensity focused ultrasound (HIFU), radiofrequency microneedling (RFM), and thermal radiofrequency (RF) for antiaging and rejuvenation treatment. Laser and RFM treatments may improve skin conditions by inducing cutaneous changes that remodel the skin matrix. METHODS: Six physicians who treat patients for skin rejuvenation reported on clinical cases from their practice using a multi-modality system with various handpieces. RESULTS: During the meeting, the advisors discussed 15 cases and agreed to select seven patients with different ages and skin phototypes receiving various treatments for photodamage of the face, neck, and décolleté. The advisors discussed why they selected the case, previous treatment, type of treatment, results, and clinical pearls. CONCLUSION: Sharing best practices in medical aesthetics using combination treatments on a single multi-modality energy-based device such as laser and MRF for facial, neck, and chest skin may support healthcare providers treating patients for skin rejuvenation to improve clinical outcomes.

RESUMO

BACKGROUND: The emergence of horizontal neck wrinkles is increasingly becoming a focal point for both cosmetic professionals and clients. Various treatment approaches must be considered to address this issue effectively, owing to its diverse underlying causes. The study explores the potential of utilizing the Endolift laser in conjunction with nanofat injection as a viable treatment option. METHODS: Twenty patients with horizontal neck wrinkles involved in the study. Ten patients underwent treatment with a combination of Endolift laser and nanofat injection and 10 patients treated with nanofat injection alone. The participants were monitored for 6 months post-treatment. Biometric measurements were utilized to assess outcomes, including changes in volume, depth, and area of the wrinkles, skin elasticity, as well as the diameter and density of the epidermis and dermis in the treated area. Skin improvement was evaluated by two independent dermatologists, who compared before and after photos in a blinded manner. Patient satisfaction levels were also documented. RESULTS: The Visioface analysis showed a notable decrease in neck wrinkle depth and area in both groups. However, the group receiving the combination treatment of Endolift laser and nanofat exhibited a significantly greater improvement compared to the group treated with nanofat alone. Skin ultrasonography results demonstrated an increase in thickness and density of the dermis and epidermis in both groups. Particularly, the group treated with Endolift laser-nanofat displayed significant enhancements in dermis and epidermis density and thickness when contrasted with the nanofat-only group. Analysis with Cutometer revealed a marked enhancement in skin elasticity in the Endolift-nanofat treated group in comparison to the nanofat-only treated group. Furthermore, in the Endolift-nanofat treated group, a substantial majority (90%) of patients exhibited improvement. Patient evaluations highlighted significant distinctions between the two groups, with 95% of patients in the Endolift-nanofat treated group demonstrating enhancement. CONCLUSION: Both methods notably enhance horizontal neck wrinkles; nevertheless, the combination of endolift laser and nanofat seems to be more efficient for treating horizontal neck wrinkles.

RESUMO

Non-insulated microneedle radiofrequency (NIMNRF) is a method of promoting dermal collagen shrinking and remodeling with minor injury reducing wrinkles. We conducted a 3-years retrospective observation on wrinkles of facial photoaging subjects treated with NIMNRF in Chinese subjects to demonstrate the efficacy and side effects. Chinese subjects clinically diagnosed as facial photoaging treated with MNRF in the Laser Center of The First Hospital of China Medical University and Guangzhou Mylike Medical Cosmetic Hospital from Jan 1, 2018 to Dec 31, 2021 were enrolled in this study. Inclusion criteria included. Each subject was treated with NIMNRF for 1-3 sessions, with a 3-month interval. At baseline and 3 months after each treatment, a Wrinkle Assessment Scale (WAS) was used to score the wrinkles in 10 areas. The total WAS score and WAS improvement rate was assessed at each time point. A total of 96 subjects, aged 25-65 years old, received at least one session of NIMNRF were enrolled. 63, 24, 9 of them received 1, 2 or 3 sessions, respectively. The total WAS score decreased from 14.65 ± 9.20 to 11.51 ± 8.70 after Session 1, from 15.92 ± 9.48 to 12.17 ± 8.83 after Session 2 and from 17.56 ± 6.99 to 11.11 ± 7.13 after Session 3 (P < 0.01). The WAS improvement rate was 25.61%, 30.69% and 39.82% after 1, 2, 3 sessions, respectively. As for subjects in different age groups, the improvement rate decreased with age, from 39.13% in 25-30 years old group to 16.39% in over 60 years old group after Session 1 (P < 0.05). Better efficacy and less sessions of treatments were conducted in younger subjects. NIMNRF can be used in the treatment of facial wrinkles in photoaging subjects, especially in youngster as better efficacy.

RESUMO

BACKGROUND: The market requires ever-faster techniques, in particular for pre-rejuvenation condition. AIM: The purpose of this study was to assess if a fractional CO2 scanner modality (called moveo) results in a faster full-face rejuvenation treatment in comparison to the standard mode, currently existing in the scanner system. MATERIALS AND METHODS: A total of 12 female patients affected by fine lines participated in a split-face clinical investigation and underwent to two sessions with a fractional CO2 laser system equipped with an existing and a faster dedicated scanner units. Pain was assessed using VAS. Three-dimensional clinical photographs were captured before, immediately after, 3 days, 14 days after the first treatment and immediately after the second treatment and 1 months after the last one. The uniformity and aesthetic coverage of treatments were assessed using dermatoscopy. Global aesthetic improvement scale (GAIS) was used. The time taken to treat the two sides of the face and all possible side effects were monitored. RESULTS: Following only two treatment session with both scanner modes, the patient's skin texture improved significantly, with fine lines reduction. There is no statistically significant difference in perceived pain between patients. The GAIS score showed satisfactory results following both modalities. The time parameters indicated that with the faster scanner mode the full-face treatment time was reduced by 30% compared to the standard one. No adverse effects were observed. CONCLUSIONS: The moveo modality provide faster treatment and a better final dermal aesthetic outcome than the standard procedure while maintaining the same safety profile.

RESUMO

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.

RESUMO

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.

RESUMO

BACKGROUND: There has been a proliferation of physicians of different levels of experience and training offering nonsurgical cosmetic procedures. Rising demand, compounded by increasing utilization of new and existing technologies by numerous physician specialties, compels discussion of adequate standardized training and patient safety. METHODS: A retrospective chart review of patients who presented to our single site dermatology clinic for managment of complications following chemical peel, laser or energy-based device treatments performed by core cosmetic physicians between the years of 2013 and 2024 was conducted. Core cosmetic physicians included plastic surgery, facial surgery/otolaryngology, oculoplastic surgery, and dermatology. Charts were reviewed for documentation of the type of complication, procedure causing the complication, and physician credentials, and referral source. RESULTS: Twenty-five patients were identified as having complications from chemical peeling, laser treatment or energy-based devices. Devices implicated included CO2 laser (fractional or fully ablative), chemical peels, 1064 nm long-pulsed Nd:YAG laser, 1320 nm Nd:YAG laser, intense pulsed light, 595 nm pulsed dye laser, Q-switched Nd:YAG laser, radiofrequency with and without microneedling, and 1550 nm erbium-doped fiber laser. Complications included hypertrophic scarring, atrophic scarring, post-inflammatory erythema, post-inflammatory hyperpigmentation, and post-inflammatory hypopigmentation. CONCLUSIONS: Even in experienced hands, complications can arise. It is imperative that all physicians offering cosmetic treatments are equipped to recognize clinical endpoints, identify and manage complications, or make a timely referral to decrease the risk of a permanent and potentially devastating esthetic outcome for patients.

RESUMO

Contemporary approaches for facial rejuvenation encompass the utilization of both ablative and nonablative laser techniques. Extensive research has elucidated the adverse consequences associated with ablative laser treatment, such as the emergence of infectious, follicular, scarring, and pigmentary alterations. Nonablative fractional lasers exhibit commendable cosmetic outcomes, characterized by a diminished incidence of complications owing to their photomechanical mechanisms, in contrast to ablative laser modalities. Nonetheless, it is imperative to acknowledge that untoward effects may still manifest. In this report, we present two cases of herpes simplex virus (HSV) reactivation subsequent to nonablative fractional resurfacing. Timely identification and the appropriate administration of antiviral agents are important, which serve as imperative measures to mitigate the long-term consequences that may arise in the event of complications.

RESUMO

Microneedle fractional radiofrequency (MFRF) has been used to improve photoaging and scars. This study aimed to evaluate the efficacy and safety of MFRF with basic fibroblast growth factor (bFGF) for facial atrophic acne scars and skin rejuvenation by blinded visual evaluation, self-report, and reflective confocal microscopy (RCM). Fifteen subjects were randomized to the MFRF with bFGF group and fifteen to the MFRF group. All subjects underwent three-session therapy and a follow-up period. Significant group differences were in ECCA, global improvement score, satisfaction, and downtime before and after treatment. Combination therapy could be more effective than monotherapy for acne scars and facial rejuvenation. In addition, RCM can be used to observe the changes in skin collagen before and after treatment in evaluating cosmetic efficacy.

RESUMO

BACKGROUND: TikTok is one of the fastest-growing social media platform, and its short-form videos have become a widely used source of health information. "Dermarolling" is a form of roller microneedling often practiced at home, and patients may be using TikTok to inform their decision to pursue this treatment and their practice of it. AIMS: This study assessed the informational content quality, source, and engagement of TikTok dermarolling videos to highlight potentially harmful social media trends. METHODS: On a predetermined date, "dermarolling" was searched on TikTok. The top 75 results were screened. Number of views, creator type, type of video, and whether risks were discussed were recorded. Information quality was assessed using the DISCERN tool. The data were stratified by creator type, and statistical analysis was performed using R version 4.3.2. Median viewership and DISCERN scores were compared using Kruskal-Wallis tests with post hoc pairwise Wilcoxon tests. Fisher's exact test was used to compare rates of risk discussion between groups. RESULTS: Sixty-one of the reviewed videos met the inclusion criteria. Influencer videos engaged the largest overall audience and had higher median viewership than other creators. Physicians, primarily dermatologists, created exclusively educational content and influencers created mostly experience-based content. Overall content quality was generally low-moderate, with a median (IQR) DISCERN score of 30.5 (26.5-33.5). Physician content had higher median DISCERN scores than influencers (p = 0.004) and others (p = 0.004). Physicians were more likely to discuss risks compared to influencers (p = 0.02). CONCLUSIONS: TikTok content on "dermarolling" was of relatively low quality, and nonphysicians command a large viewership. Physician-created content is often of higher informational quality, and dermatologists should escalate their efforts to engage patients in this space to mitigate the effects of potential misinformation.

RESUMO

BACKGROUND: To evaluate the efficacy and safety of stromal vascular fraction (SVF), platelet rich plasma (PRP), and 1064-nm Q-switched Nd:YAG laser in reducing nanofat treated dark circles and wrinkles under the eyes. METHOD: This study was a single-blinded randomized clinical trial conducted on patients with suborbital darkening under the eyes that randomly divided into control and case groups. In the control group, 15 patients were treated with one session of nanofat injection only, and five patients of each intervention groups received one session of nanofat+SVF injection, nanofat+PRP injection, and nanofat injection+Nd:YAG laser, respectively. Assessments methods were (1) evaluation of the degree of darkness and repair under the eyes by a blinded dermatologist based on clinical photographs, (2) investigating patient satisfaction, (3) using biometric variables for color, thickness, and density of the skin (only 3 months after the treatment), and (4) recording the possible adverse effects. CONCLUSION: In terms of the extent of reduction in the intensity of darkness under the eyes, the combined treatment of nanofat injection together with SVF, PRP, and Nd:YAG laser had a much greater therapeutic effect than nanofat injection alone. In all three groups of combined treatments, patients were 100% satisfied. In terms of biometric variables, amount of changes in colorimeter, complete and dermal thickness, complete and dermal density, between the different groups was statistically significant. The use of combined treatments including nanofat with SVF injection, PRP, and 1064 Q-switched Nd:YAG laser may be more effective than nanofat alone, in reducing infraorbital dark circles and wrinkles.

RESUMO

BACKGROUND: Ultrasound energy can successfully treat fine lines and wrinkles, as well as lift the eyebrow and submentum. Ultrasound waves of high intensity induce thermal injury in the dermis with subsequent tissue remodeling. OBJECTIVE: To examine the utility of a novel ultrasound device that utilizes high-intensity, high-frequency, parallel ultrasound beams to improve the clinical appearance of cellulite on the thighs and buttocks. MATERIALS AND METHODS: A prospective, multicenter, clinical study investigated this novel ultrasound device using 2 treatments. RESULTS: Sixty-five subjects completed both treatments. The mean age was 46 years, and 100% were women. Fitzpatrick skin types I to VI were represented. Assessments compared 3-month follow-up with baseline. Two blinded reviewers agreed in identifying pretreatment and post-treatment photographs for 89.2%. For Cellulite Severity Scale rating, there was significant improvement of 1.61 units ( p < .001). For cellulite Global Aesthetic Improvement Scale (GAIS), 89.2% had improvement, with a mean of 0.87 units ( p < .001). For Laxity Scale rating, there was significant improvement of 0.70 units ( p < .001). For skin laxity GAIS, 89.2% had improvement, with a mean of 0.76 units ( p < .001). No device-related adverse events occurred. CONCLUSION: A novel ultrasound device that utilizes high-intensity, high-frequency, parallel ultrasound beams can safely and effectively improve the clinical appearance of cellulite on the thighs and buttocks.

RESUMO

BACKGROUND: Striae distensae (SD) are cutaneous lesions that are caused by hormones or mechanical stress leading to rapid expansion of skin. Therefore, SD are now a cosmetic concern. However, improving SD is notoriously difficult. Among different treatments, energy-based devices (EBDs) are much more effective and controllable. OBJECTIVE: The aim of this review was to determine the most effective type of EBD for improving the appearance of striae. MATERIALS AND METHODS: The study was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The population comprised patients suffering from striae. Different types of EBDs used to improve striae were compared. The primary outcome of the reduction in the width of striae was evaluated. A random-effects model was performed. The means and standard deviations were extracted. RESULTS: Eighteen randomized controlled trials were included. The network meta-analysis revealed that after a comparison among the 4 types of EBDs, no significant differences were observed in the reduction of striae width. CONCLUSION: Radiofrequency, ablative lasers, nonablative lasers, and intense pulsed light are all effective treatments for reducing the striae width. None of them was superior to the others. However, radiofrequency and ablative lasers may have the highest chance of improving the appearance of striae.

RESUMO

OBJECTIVES: There remains an unmet need for a laser-enabled tissue coring device that can effectively improve face and neck skin laxity and rhytides. We investigate a novel 2910 nm erbium-doped fluoride glass fiber laser (2910 nm fiber laser) (UltraClear; Acclaro Medical) for laser-coring of submental tissue. METHODS: Five subjects, Glogau scale III-IV, were treated with a single pulse of the laser-coring mode of the 2910 nm fiber laser in the submentum. A 4 mm punch biopsy was immediately performed. Biopsy specimens were sectioned and stained with hematoxylin and eosin and placed on glass slides. All sections were reviewed, and sections containing the center of the transected core were analyzed for depth and diameter of the ablative microchannel and width of the surrounding zone of coagulation. RESULTS: A total of 15 intact micro-cores were analyzed. Histological analysis revealed an average ± standard deviation microchannel diameter of 242.5 ± 65.2 µm, an average ablative depth of 980 ± 318.8 µm, and an average zone of coagulation of 104 ± 32 µm. CONCLUSIONS: Laser-enabled tissue coring with a novel 2910 nm fiber laser can safely achieve a wider microchannel diameter with ablative depth extending to the mid and deep dermis, which has the potential for collagen contraction and tissue tightening. Laser-coring to this ablation diameter and depth and with the surrounding zone of coagulation was found to be safe without adverse effects of post-inflammatory erythema or scarring in our study.

RESUMO

BACKGROUND: Microneedling is used to enhance transcutaneous drug delivery. However, the extent to which microneedling devices impact filler delivery and whether this varies by filler type, microneedling device type, and treatment sequence is not known. OBJECTIVE: To histologically assess and quantify the delivery of commonly used fillers through microneedling, using both a microneedling pen and a microneedling roller. In addition, the authors investigated whether there is a variation in filler delivery based on the sequence of microneedling in relation to topical filler application. METHODS: Ex vivo human abdominal skin samples were subjected to microneedling pen or microneedling roller treatment. Black tissue marking ink, hyaluronic acid, poly- l -lactic acid, or undiluted calcium hydroxyapatite was topically applied before or immediately after microneedling treatment. RESULTS: Histological evaluation revealed a notable presence of black ink within channels formed by both microneedling treatments (15.5%-98.1%), whereas there was limited presence of the various filler types tested (0%-6.6%) in all settings. Topical application before microneedling treatment led to relatively higher filler/ink deposition within the channels formed by the microneedling treatments compared with topical application after microneedling. CONCLUSION: Transcutaneous delivery of fillers was not significantly helped by microneedling treatment, whereas the microneedling devices demonstrated effective delivery of an aqueous solution.

RESUMO

INTRODUCTION: Striae distensae (SD), or stretch marks, result from rapid stretching of the skin due to various factors. Conventional treatments often yield unsatisfactory results, leading to the exploration of alternative methods. Laser-induced microjet technology offers a promising approach for drug delivery to target areas. This study investigates the efficacy of using a microjet injector with poly-d,l-lactic acid for treating SD. METHODS: Four female participants with SD were treated with poly-d,l-lactic acid solution using a microjet injector over five sessions. Patients were assessed based on severity scales before and after treatment. Topical anesthetics were applied to minimize discomfort. Injection techniques were optimized to reduce side effects such as bleeding and pain. RESULTS: All patients showed significant improvement in SD appearance after 5-7 treatments. Assessment scales indicated positive outcomes both immediately after treatment and at the 32-week follow-up. Minimal side effects, primarily petechiae, were observed. DISCUSSION: Laser-induced microjet technology offers several advantages, including rapid drug delivery and mechanotransduction effects, promoting skin regeneration. Poly-d,l-lactic acid injections demonstrated effectiveness in treating SD, particularly when delivered via microjet injectors. Patients expressed high satisfaction due to the procedure's minimal invasiveness and quick recovery. CONCLUSION: Utilizing a needleless microjet injector with poly-d,l-lactic acid shows promise as a treatment for SD, typically requiring 5-7 sessions for optimal results.
