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: An accumulation of adipose tissue on the lateral abdomen (flanks) coupled with muscle deconditioning negatively affects core stability, muscular balance, and the intrinsic strength essential for maintaining optimal body mechanics and posture. This lateral fat accumulation and diminution of muscle result in an unfavorable abdominal profile and present challenges in finding appropriately fitting attire. OBJECTIVES: The aim of this study was to explore the effectiveness and safety of the simultaneous application of high-intensity focused electromagnetic (HIFEM) therapy and synchronized radiofrequency for sculpting the lateral abdomen. METHODS: All patients were scheduled to undergo four 30-minute treatments at approximately weekly intervals and then subsequent follow-up visits at 1 month and 3 months after the last treatment. The primary evaluation assessed changes in the oblique muscles, adipose tissue thickness, and cross-sectional area (CSA) by MRI performed at baseline and follow-ups. The secondary outcomes included digital photographs of the treated areas, a Subject Satisfaction Questionnaire, and a Therapy Comfort Questionnaire. Adverse events and side effects were monitored throughout the study duration. RESULTS: The muscle tissue showed a substantial increase in thickness (+27.2%) and CSA (+29.0%). The adipose tissue measurements showed a decrease of -30.5% in CSA and -28.8% in thickness. As secondary outcomes, 81.8% of patients reported feeling more toned, and 84.9% of patients found the treatment comfortable and reported less than mild pain. CONCLUSIONS: Based on the evaluation, the study suggests that the simultaneous application of HIFEM and synchronized radiofrequency is safe and effective for reducing adipose tissue and strengthening muscle in the area of the lateral abdomen.

RESUMO

BACKGROUND: Noninvasive cosmetic body contouring techniques are growing rapidly, and noninvasive lipolysis has been shown to have low pain, little downtime and produce consistent long-term results. The objective of this study was to evaluate the safety and efficacy of a 1064 nm diode laser combined with vacuum assisted PEMF and RF energies for noninvasive fat reduction of the abdomen and flanks. METHODS: Subjects received a series of three treatments 8 weeks apart, each consisting of a diode laser session, followed by vacuum assisted PEMF and RF. Before and after photographs were graded for overall fat reduction by three blinded evaluators. Ultrasound was used to measure changes in the thickness of adipose tissue. Subject satisfaction was assessed using the 5-Point Likert Subject Satisfaction Scale and a subject questionnaire at 16 and 24-week follow-up visits. Throughout each treatment, the subjects were given the Wong-Baker Faces Pain Rating Scale (WBFS) to assess discomfort and pain of the treatment. RESULTS: Thirty-nine subjects (average age 48.6 years) from four clinical sites were enrolled. Evaluators identified the correct before and after images 73.1% of the time and images were graded an average score of 1.12 (SE 0.1) correlating to more than a "slight change." Adipose tissue was reduced by 31.9% based on ultrasound measurements (p < 0.001). Subject satisfaction was high with an average satisfaction score of 7.8 ("satisfied") out of 10. The overall pain over time on average was rated "hurts little bit." Ninety percent of subjects reported either a mild, moderate, or significant improvement in their fat reduction and skin surface appearance. Almost 77% (76.7%) of subjects reported that they would recommend the treatment to a friend. There were six reports of adverse events related to the device during the study that were all transient and resolved rapidly. CONCLUSION: A significant reduction of subcutaneous adipose tissue was measured after treatment with a combination of diode laser and vacuum assisted PEMF and RF. Treatment pain was low and tolerable, and subjects had high levels of satisfaction with the results.

RESUMO

BACKGROUND: Aging is a multifactorial response to genetic preprogramming nuances, sun exposure, and ultraviolet radiation. Recently, there has been a paradigm shift toward minimally invasive rejuvenation. OBJECTIVE: This prospective multicenter study aims to evaluate the efficacy and safety of a novel hands-free bipolar bulk radiofrequency (RF) device in terms of improvement in skin appearance. PATIENTS AND METHODS: This multicenter prospective study enrolled subjects aged 35 to 75 years with visible signs of aging. The primary objective was to evaluate skin appearance pretreatment and at 1, 3, and 6 months after the final treatment. Each patient received 3 total treatments to the chin and cheeks using the hands-free RF device spaced 2 weeks apart. RESULTS: In total, data from 87 patients were assessed from 6 treatment sites. The average age was 54 years (range 35-75 years). Most patients were female (97%), and Fitzpatrick skin types I to V were represented. Overall, patients found the procedures to be relatively pain-free, and both patients and investigators felt they noted some improvement in their skin appearance. Histological sections demonstrated an increase in collagen or elastic fibers within the papillary dermis. CONCLUSION: This study supports the use of this novel noninvasive hands-free bipolar facial remodeling device for the improvement of skin appearance.

RESUMO

BACKGROUND: Patients frequently seek treatment for vascular and pigmented lesions. More recently, a novel, variable-sequenced, long-pulsed, 532-nm and 1,064-nm laser with cryogen spray cooling was developed to offer greater flexibility in treatments. OBJECTIVE: A prospective clinical trial evaluated the safety and efficacy of a novel, variable-sequenced, long-pulsed, 532-nm and 1,064-nm laser with cryogen spray cooling (DermaV, Lutronic, South Korea). MATERIALS AND METHODS: Subjects with vascular and/or pigmented lesions were enrolled and underwent laser treatments. RESULTS: Twenty-three subjects were enrolled with vascular lesions (39.1%), pigmented lesions (17.4%), and both (43.5%). Mean age was 53.1 years, and 91.3% were women. Fitzpatrick skin types II-IV were included. All subjects were treated with 532 nm, and 4 were also treated with 1,064 nm. According to 4 blinded physician reviewers, correct before and after photographs were selected in 94.7%, 92.1%, 84.2%, and 76.3% of cases. Overall, 86.8% were responders, meaning that at least 3 of 4 reviewers agreed. For Global Aesthetic Improvement Scale, improvement occurred in 81.6%, 81.6%, 81.6%, and 76.3% of cases. No serious adverse events occurred. Overall, 87.0% of subjects reported being very satisfied or satisfied. CONCLUSION: A novel, variable-sequenced, long-pulsed, 532-nm and 1,064-nm laser with cryogen spray cooling can safely and effectively improve vascular and pigmented lesions.

RESUMO

BACKGROUND: The Fraxel Dual laser system (Solta Medical, Inc., Bothell, WA) contains a 1,550 and 1,927 nm wavelength single handpiece with different indications for each wavelength. OBJECTIVE: To discuss treatment setting recommendations and best practices for select on-label and investigational applications of the 1,550 and 1,927 nm dual laser system. MATERIALS AND METHODS: Eight board-certified dermatologists with 10 or more years of experience with the 1,550 and 1,927 nm laser system completed an online survey about their clinical experience with the system and then participated in a roundtable to share clinical perspectives and best practices for using the laser system. RESULTS: For all Fitzpatrick skin types, treatment recommendations were described for selected approved indications for the 1,550 and 1,927 nm laser system, including both lasers in combination. Treatment recommendations were also reached for investigational applications with the 1,550 nm laser and 1,927 nm laser. Best practices for using the lasers during the treatment session to achieve optimal outcomes and decrease the post-treatment recovery time were compiled. CONCLUSION: The 1,550 and 1,927 nm dual laser system is effective for a wide range of aesthetic and therapeutic applications, on and off the face and across all Fitzpatrick skin types.

RESUMO

BACKGROUND: Fractional radiofrequency (FRF) technology has been shown in clinical studies to improve skin laxity, and to treat various skin conditions related to aging and alternate collagen structures such as rhytids. The objective of this clinical study was to evaluate the safety and performance of FRF (up to 124 mJ per pin) for the treatment of facial rhytids, emphasizing the upper lip and perioral areas. METHODS: Enrolled subjects received a series of 3 FRF treatments to the full face, 3 to 5 weeks apart. Immediately after treatment, the subjects were given a scale to assess pain and tolerability of the treatment. Subject satisfaction questionnaires were completed at follow-up visits at 6 and 12 weeks post final treatment. Before and after photographs were graded for change by three blinded evaluators using the Fitzpatrick Wrinkle and Elastosis Scale (FWES) and the Global Aesthetic Improvement Scale (GAIS). RESULTS: Image sets of 10 enrolled subjects (average age 62.7 years) were assessed by blinded evaluators. The overall face FWES score improved from 5.97 (SE 0.20) at baseline to 5.78 (SE 0.22) at 12-week follow-up. The GAIS improved by 0.4 points and was significant compared to baseline (P = 0.0004). Subject satisfaction was high with subjects giving an average satisfaction score of 3.2 (“satisfied”) out of 4. Pain was rated “mild to moderate” with an average of 3.9 on a 11-point Wong Baker FACES Scale. Ninety percent (90%) of subjects reported either a mild, moderate, or significant improvement to their treatment area. Eighty percent (80%) of subjects reported that they would recommend the treatment to a friend. There were no reports of adverse events or unanticipated side effects during the duration of the study. CONCLUSION: A statistically significant reduction in rhytids of the upper lip and the perioral area, was found, as evaluated by independent blinded evaluators. There were no adverse events. Treatment pain was low and tolerable, and subjects had high levels of satisfaction with the results at last follow-up. J Drugs Dermatol. 2022;21(1):43-48. doi:10.36849/JDD.6492.

RESUMO

BACKGROUND: Fractional laser treatment was introduced in 2004 as a non-invasive technique to treat sun-damaged and aging skin. Since then, numerous ablative and non-ablative photothermolysis technologies and devices have been introduced, increasing the options for clinicians and patients but also increasing the complexity regarding which system to use and the techniques to optimize outcomes. No two devices are the same and the user-manuals preset dosimetry does not address many clinical situations, which can create confusion for new and inexperienced users. METHODS: An online survey addressing use of a 1550 nm /1927 nm dual wavelength, non-ablative, fractional laser was sent to eight (8) US board certified dermatologists with extensive experience in the use of the device. The survey included 39 questions, addressing experience, best practices and recommendations for use. RESULTS: The survey data suggests that the device can be used to treat patients of all ages and skin types for indications including photoaging and photodamage, periorbital wrinkles, freckles, (ephelides), solar lentigines, poikiloderma, scarring due to acne or surgery. It can be used on both facial and non-facial areas, including neck, chest, hands, arms, abdomen, legs, and buttocks. Unexpected and adverse effects were rarely reported and those that did were mild and transient. CONCLUSIONS: This position paper provides practical real-world guidelines resulting from a small survey of experienced users, for new and early uses of the novel 1550 nm /1927 nm dual wavelength, non-ablative, fractional laser.

RESUMO

The coronavirus pandemic (COVID-19) has served as a call-to-arms in preparing practices for the next disaster whether it is another infectious disease or a flood, hurricane, earthquake, a sustained power outage, or something else. A group of predominantly core aesthetic physicians discussed the various aspects of their office procedures that warrant consideration in a proactive approach to the next pandemic/disaster-related event. This guide does not set a standard of practice but contains recommendations that may avoid some of the "lessons learned" with the COVID-19 pandemic. In this paper, the board-certified core aesthetic physicians classified these recommendations into four generalized areas: Practice Management; Supplies and Inventory; Office Staffing Considerations and Protocols; and Patient Management Strategies. Proactive strategies are provided in each of these categories that, if implemented, may alleviate the processes involved with an efficient office closure and reopening process including, in the case of COVID-19, methods to reduce the risk of transmission to doctors, staff, and patients. These strategies also include being prepared for emergency-related notifications of employees and patients; the acquisition of necessary equipment and supplies such as personal protective equipment; and the maintenance and accessibility of essential data and contact information for patients, vendors, financial advisors, and other pertinent entities.J Drugs Dermatol. 2021;20(1):10-16. doi:10.36849/JDD.5803.

RESUMO

BACKGROUND: Despite the proven efficacy of liposuction, there is a population of patients who prefer non-surgical alternatives. Laser hyperthermia-induced lipolysis has emerged as one non-invasive alternative to liposuction. OBJECTIVES: The authors sought to evaluate the safety and efficacy of a 1060-nm (±10 nm) diode laser for non-invasive fat reduction of the abdomen. METHODS: This single-arm, 2-center study enrolled 30 patients. Patients received a 25-minute 1060-nm diode laser treatment on their abdomen. Ultrasound adipose measurements, body weight, and circumference were taken at baseline and at 6- and 12-week follow-up visits. Blinded evaluators identified "before" and "after" photos of each patient. A patient satisfaction questionnaire was completed by each patient at study exit. RESULTS: A total 29 patients completed all treatment and follow-up visits. Ultrasound images showed an adipose reduction of 8.55% at 12 weeks post-treatment (P < 0.0001). Blinded evaluators correctly identified 67% of the pre- and post-treatment images at site 01 (Sacramento, CA) and 56% at site 02 (Dallas, TX). Satisfaction was high, with 72% of patients reporting being either "satisfied" or "very satisfied" with their results on a 5-point Likert scale. Pain was rated as mild by 62% of patients, moderate by 38%, and severe by none on the Wong-Baker Scale. CONCLUSIONS: These results indicate that a single treatment with a 1060-nm (±10 nm) diode laser, per the treatment protocol, is safe and effective in reducing unwanted fat in the abdomen as objectively measured employing ultrasound. The treatment was well-tolerated among all patients, with minimal discomfort reported and high patient satisfaction.

RESUMO

BACKGROUND: In addition to reducing subcutaneous fat for body contouring, some patients are interested in toning the underlying muscle layer. OBJECTIVE: This feasibility study evaluated the safety and efficacy of electromagnetic muscle stimulation (EMMS) alone, cryolipolysis alone, and cryolipolysis with EMMS for noninvasive contouring of abdomen. METHODS: Abdomens of 50 subjects were treated in a study with 3 cohorts: EMMS alone, Cryolipolysis alone, and Cryolipolysis + EMMS in combination. Electromagnetic muscle stimulation treatments were delivered in 4 sessions over 2 weeks. Cryolipolysis treatments were delivered in one session. Combination treatments consisted of one cryolipolysis and 4 EMMS visits. Efficacy was assessed by independent physician Global Aesthetic Improvement Scale (GAIS), circumferential measurement, Subject GAIS (SGAIS), and Body Satisfaction Questionnaire (BSQ). RESULTS: Safety was demonstrated for all study cohorts with no device- or procedure-related adverse events. Independent photo review showed greatest mean GAIS score for the Cryolipolysis + EMMS cohort followed by Cryolipolysis only, then EMMS only cohort. BSQ showed greatest average score increase for Cryolipolysis + EMMS cohort followed by Cryolipolysis only cohort, then EMMS only cohort. Mean circumferential reduction measurements were greatest for Cryolipolysis + EMMS cohort followed by Cryolipolysis only, and then EMMS only cohort. The mean SGAIS improvement score was equal for the Cryolipolysis only and Cryolipolysis + EMMS cohorts, followed by the EMMS only cohort. CONCLUSION: A multimodal approach using cryolipolysis and EMMS was safe and demonstrated enhanced body contouring efficacy for this feasibility study.

RESUMO

BACKGROUND: Nanosecond pulsed electric field (nsPEF) technology involves delivery of ultrashort pulses of electrical energy and is a nonthermal, drug-free technology that has demonstrated favorable effects on cellular structures of the dermis and epidermis. OBJECTIVE: Determine the tolerability and effectiveness of nsPEF treatment of sebaceous gland hyperplasia (SGH). METHODS: This study was a prospective, randomized, open-label, multisite, nonsignificant risk trial in which each subject served as their own control. After injection of local anesthetic, high-intensity, ultrashort pulses of electrical energy were used to treat 72 subjects resulting in a total of 222 treated lesions. Subjects returned for 3 to 4 follow-up evaluations with photographs. RESULTS: At the final study visit, 99.6% of treated SGH lesions were rated clear or mostly clear and 79.3% of the subjects were satisfied or mostly satisfied with the outcome. At 60 days after nsPEF treatment, 55% of the lesions were judged to have no hyperpigmentation and 31% exhibited mild post-treatment hyperpigmentation. At the last observation for all lesions, 32% of the 222 lesions were noted as having slight volume loss. CONCLUSION: Nanosecond pulsed electric field procedure is well tolerated and is very effective in the removal of SGHs. TRIAL REGISTRATION: ClinicalTrials.gov NCT03612570.

RESUMO

BACKGROUND: Cellulite is a common female cosmetic concern for which there are few treatment options with long-term effectiveness data. The aim of this multisite prospective registry study was to collect observational data on the real-life clinical use of a tissue stabilized-guided subcision (TS-GS) system for long-term improvement of cellulite appearance. METHODS: Fifty-three subjects were enrolled and received a single treatment using the TS-GS system. Physicians treated the subjects according to their standard of care. Global Aesthetic Improvement Scale (GAIS) was completed by the patient and clinician assessing overall aesthetic improvement after 180 days. Treatment parameters, pain scores, quality of life data, and expected treatment effects and adverse events were also recorded throughout the study. RESULTS: The patient and physician GAIS scores at Day 180 revealed an overall improvement in 91% and 96% of patients, respectively. Quality of life and self-confidence scores also improved through 180 days. No serious adverse events were reported. Expected treatment effects were similar to those reported in the pivotal trial supporting FDA clearance. CONCLUSION: This study demonstrated significant improvement in the appearance of cellulite after a single treatment session in patients with moderate-to-severe cellulite. These results are consistent with the previously published the pivotal study data.

RESUMO

Non-surgical fat reduction procedures have gained in popularity over the past few years and remain in great demand. The process results in accumulation of breakdown products, lipid droplets, that are slowly absorbed over a period of months. This paper outlines the physiological process whereby lipid droplets are absorbed through a process of autophagy (lipophagy) involving a repackaging of these droplets to smaller sizes so that macrophages can then cope with digestion of these very large particles. Furthermore, a fat compartment is described within the dermis surrounding the tail of the hair follicle, which is attracting much attention due to its unique phenotype, function, and connection to the deeper subcutaneous fat compartment. This provides an entry route for direct signaling to the subcutaneous fat. Related to these novel concepts, peptides can be designed in liposomal delivery systems to target lipid droplet breakdown via the hair follicle entry route. This concept is elucidated in this paper.

RESUMO

OBJECTIVE: The purpose of this study was to determine the efficacy and safety of a 1060 nm diode laser system with multiple handpieces for permanent hair reduction. STUDY DESIGN: An open-label, prospective, multi-center study of adult subjects (≥18 years old) of any skin type, having dark brown or black hairs at the areas to be treated and seeking to permanently remove hair underwent six treatment sessions, at 4 to 6 weeks intervals with either a 1060 nm chilled sapphire tip or seven treatment sessions, at 6 weeks interval with a large spot vacuum based handpiece. METHODS: Subjects received treatments on various body areas using chilled sapphire tip or large spot size vacuum-assisted handpiece. Hair counts as well as assessments of hair coarseness and color were performed using photographs taken at baseline, prior to pre-selected treatments and at the follow up visits. At every visit, immediate skin responses and adverse events were evaluated by the investigator and treatment associated pain level experienced was quantified by the subjects. Subjects were asked to assess their improvement and satisfaction at pre-selected treatment sessions and at all the follow up visits. A sub group of subjects that were treated with the large spot size vacuum-assisted handpiece contributed two punch biopsy specimens for histological analysis. RESULTS: A total of 16 subjects age 33 ± 10.9 years were treated with the chilled sapphire tip, and 26 subjects age 36.3 ± 7.67 years were treated with the large spot size vacuum-assisted handpiece. Treatment with chilled sapphire tip yielded a mean of 68%, 82%, and 76% skin type-independent hair reduction in axillae, shin, and arm, respectively, at 6 month follow up visit as compared to baseline. The majority of subjects (≥80%) rated their hair reduction to be either good or very good and were satisfied to highly satisfied with the outcome. Treatment with the large spot size vacuum-assisted handpiece, was most effective in axillae and calves, with a 77.9% and 78.5% hair count reduction, respectively, at the 6 month follow up visit. Subjects reported high satisfaction and improvement throughout the treatments and follow-up periods. Treatments with both handpieces were not associated with intolerable pain levels and common post procedural responses included mild to moderate erythema and/or edema. CONCLUSION: The 1060 nm diode laser system is safe and effective for hair removal and long-term hair reduction in all skin types including darkly pigmented individuals. Lasers Surg.

RESUMO

BACKGROUND AND OBJECTIVES: Cryolipolysis is a safe, effective non-surgical procedure to reduce fat. For most cryolipolysis treatments, tissue is pulled between parallel cooling plates with a treatment duration of 60 minutes. A novel contoured cup, medium-sized applicator was developed to increase tissue contact with reduced skin tension and reduced treatment time. This prototype contoured cup was investigated with a standard cryolipolysis applicator to evaluate safety, efficacy, and patient preference. STUDY DESIGN/MATERIAL AND METHODS: A prototype CoolCup medium-sized vacuum applicator (CoolSculpting System, ZELTIQ Aesthetics) was used to treat n = 19 subjects in the flanks. Randomly assigned, one flank received standard treatment with the CoolCore applicator (-10°C for 60 minutes). The contralateral flank received treatment from the CoolCup (-11°C for 35 minutes). The clinical study primary efficacy endpoint was 70% correct identification of baseline photographs by independent physician review. Incidence of adverse device effects was monitored. Fat layer reduction was measured by ultrasound and subject surveys were administered 12 weeks post-treatment. RESULTS: Equivalent efficacy was demonstrated between the CoolCore standard treatment and the prototype CoolCup. Independent review from three blinded physicians found 81% correct identification of baseline photographs for the standard treatment and 79% for the CoolCup. Ultrasound measurements indicated mean fat layer reduction of 4.38 mm for the standard treatment and 4.40 mm for the CoolCup; no statistically significant difference was found when comparing treatment efficacy of the two applicators (P = 0.96). Patient questionnaires revealed 85% preferred CoolCup because of shorter treatment duration and greater comfort. Procedural assessments revealed 45% lower pain scores for CoolCup. Immediate post-treatment clinical assessments revealed 82% less bruising. Typical side effects, such as numbness and erythema, were similar. There were no adverse events. CONCLUSION: This clinical study of a prototype medium-sized vacuum applicator with a cooled contoured surface indicates that the CoolCup produces equivalent safety and efficacy to the standard CoolCore cryolipolysis applicator. With a 42% reduction in treatment time, the procedure was found to be more comfortable because of lower vacuum skin tension and shorter treatment duration. Lasers Surg.

RESUMO

BACKGROUND: The demand for cosmetic treatments with lasers and energy-based devices has increased among men, but there is a dearth of literature that addresses the approach and treatment of cosmetic male patients. OBJECTIVE: To summarize common cosmetic concerns for which male patients seek cosmetic treatments and to provide sex-specific recommendations for the lasers and energy-based devices that can be used for treatment. MATERIALS AND METHODS: The authors conducted a literature search using the PubMed/MEDLINE and Google Scholar databases using the search terms male, men, gender, and cosmetic dermatology. RESULTS: The authors review sex-specific treatment recommendations regarding the use of lasers and energy-based devices for the conditions for which men most commonly seek cosmetic treatment, which include photo-/actinic damage, acne scarring, rhinophyma, hair removal, axillary hyperhidrosis, and loose neck/submental skin. Cosmetic issues the authors will touch on, but whose approaches or considerations vary less in men compared with women, are hyperpigmentation, vascular lesions, and facial rejuvenation. CONCLUSION: Sex-specific treatment approaches with lasers and energy-based devices should be used to best serve male cosmetic patients.

RESUMO

BACKGROUND: Currently, the isotretinoin (13-cis-retinoic acid) package insert contains language advising the discontinuation of isotretinoin for 6 months before performing cosmetic procedures, including waxing, dermabrasion, chemical peels, laser procedures, or incisional and excisional cold-steel surgery. It is common practice to follow this standard because of concerns regarding reports of sporadic adverse events and increased risk of scarring. OBJECTIVE: To develop expert consensus regarding the safety of skin procedures, including resurfacing, energy device treatments, and incisional and excisional procedures, in the setting of concurrent or recent isotretinoin use. MATERIALS AND METHODS: The American Society for Dermatologic Surgery authorized a task force of content experts to review the evidence and provide guidance. First, data were extracted from the literature. This was followed by a clinical question review, a consensus Delphi process, and validation of the results by peer review. RESULTS: The task force concluded that there is insufficient evidence to justify delaying treatment with superficial chemical peels and nonablative lasers, including hair removal lasers and lights, vascular lasers, and nonablative fractional devices for patients currently or recently exposed to isotretinoin. Superficial and focal dermabrasion may also be safe when performed by a well-trained clinician.

RESUMO

BACKGROUND AND OBJECTIVES: Cryolipolysis has previously received FDA clearance for fat reduction in the abdomen, flanks, and thighs. There is also interest in small volume fat reduction for areas such as the chin, knees, and axilla. This article reports the results of a cryolipolysis pivotal IDE study for reduction of submental fullness. STUDY DESIGN/MATERIAL AND METHODS: A prototype small volume vacuum applicator (CoolMini applicator, CoolSculpting System, ZELTIQ Aesthetics) was used to treat 60 subjects in the submental area. At each treatment visit, a single treatment cycle was delivered at -10°C for 60 minutes, the same temperature and duration used in current commercially-available cryolipolysis vacuum applicators. At the investigator's discretion, an optional second treatment was delivered 6 weeks after the initial treatment. The primary efficacy endpoint was 80% correct identification of baseline photographs by independent physician review. The primary safety endpoint was monitoring incidence of device- and/or procedure-related serious adverse events. Secondary endpoints included assessment of fat layer thickness by ultrasound and subject satisfaction surveys administered 12 weeks after final cryolipolysis treatment. RESULTS: Independent photo review from 3 blinded physicians found 91% correct identification of baseline clinical photographs. Ultrasound data indicated mean fat layer reduction of 2.0 mm. Patient questionnaires revealed 83% of subjects were satisfied, 80% would recommend submental cryolipolysis to a friend, 77% reported visible fat reduction, 77% felt that their appearance improved following the treatment, and 76% found the procedure to be comfortable. No device- or procedure-related serious adverse events were reported. CONCLUSION: The results of this clinical evaluation of 60 patients treated in a pivotal IDE study demonstrate that submental fat can be reduced safely and effectively with a small volume cryolipolysis applicator. Patient surveys revealed that submental cryolipolysis was well-tolerated, produced visible improvement in the neck contour, and generated high patient satisfaction. These study results led to FDA clearance of cryolipolysis for submental fat treatment.
