Abstract
Energy-based devices are used to improve features of appearance for aesthetic reasons while avoiding more invasive methods. Examples of treatment targets are the reduction of wrinkles, sagging, unwanted skin lesions, body hair and excess fatty tissue, and the enhancement of muscle tissue. One treatment modality is the use of electromagnetic fields (EMF, 0‒300 GHz). The present work aims to give an up-to-date survey of cosmetic applications of EMF for professional use with an assessment of client and worker exposure and possible adverse effects. A systematic search was conducted for peer-reviewed articles (2007-2022), patents, premarket notifications, manufacturer data, and adverse effects reports. Five categories of cosmetic EMF device with increasing frequency were identified: sinusoid low frequency magnetic fields for lipolysis; pulsed low frequency magnetic fields for skin rejuvenation; pulsed low frequency magnetic fields for muscle building; radiofrequency EMF for lipolysis or skin rejuvenation; microwaves for hair removal or hyperhidrosis. In the vicinity of the last four device categories, there is a potential for exceeding the occupational exposure limits in the European Union EMF Directive, which could lead to nerve or muscle stimulation, burns or overheating. There are also potential hazards for clients or workers wearing active or passive medical devices. The severity of reported adverse effects increases with EMF frequency.

Abstract
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.

Abstract
Background Surgeons and providers in aesthetic medicine seek noninvasive devices that can be utilized for safe, efficient, and effective body contouring. Patient demand has propelled the development of novel devices that can simultaneously improve skin laxity, adipolysis along with stimulation of muscle hypertrophy. Objectives To determine the efficacy of body contouring after 3 treatments using the noninvasive Transform (InMode, Lake Forest, CA) device. Methods A prospective, multicenter study was performed. Outcomes evaluated include: standardized caliper and ultrasound measurements of abdominal skin/soft-tissue thickness, waist circumference, histologic evaluation, patient comfort, and satisfaction assessments. Results Forty-four patients were successfully enrolled in the study and completed the series of 3 treatments which involved combined electrical muscle stimulation (EMS) and noninvasive bipolar radiofrequency (RF). Abdominal ultrasound measurements reveal a decrease in soft-tissue thickness (average 3.1 mm; P = .001), there was a significant decrease in caliper measurements of periumbilical skin thickness (P < .003), and the average reduction of abdominal circumference was 1.9 cm (P < .0001) 3 months after the treatment series. Histology confirmed subcutaneous adipolysis without damaging the dermal layer. Patients reported a high degree of satisfaction with the overall result (P = .003) and that each of the 3 treatments were progressively more comfortable (P < .005). Conclusions This study demonstrates that a series of simultaneous noninvasive RF with EMS treatments to the abdomen decreases subcutaneous soft-tissue thickness of the treated area. These comfortable treatments ultimately result in a high degree of patient satisfaction at 3 months. Level of Evidence 4

Abstract
BACKGROUND Emsculpt Neo (EmSculpt NEO Device, BTL Industries, Inc.) is a FDA-cleared noninvasive body contouring treatment for increasing muscle tone and/or reducing fat. The device uses high-intensity electromagnetic energy to stimulate muscle contractions and to build muscle mass (Emsculpt) or a combination of electromagnetic energy with radiofrequency (Emsculpt NEO) to produce a synergistic effect of building muscle mass and reducing fat. In this study, we conduct a high-quality systematic review to evaluate outcomes for Emsculpt and Emsculpt NEO treatments for noninvasive body contouring. METHODS An electronic search was performed of the PubMed, MEDLINE, Embase, and Web of Science databases using the key terms "High intensity focused electromagnetic therapy; HIFEM; Emsculpt; Emsculpt NEO; BTL Industries." The search included all articles published in English through January 2023. Inclusion criteria included articles noninvasive body contouring and reporting at least one outcome of interest (clinical or patient-reported outcomes). Methodological quality and risk of bias were assessed using the GRADE criteria. Articles involving applications other than for body contouring, animal studies, and review articles were excluded. RESULTS Of the 159 articles identified in the initial search strategy, 51 met relevance based on abstract screening. Fifteen clinical studies were identified, including Emsculpt (n=11) and Emsculpt NEO (n=2). The typical protocol involved four treatments given over a 2-4-week period (range 3-8 treatments) with increase to 100% intensity setting and 1-6-month follow-ups. No complications were reported. Abdominal measurements were obtained using imaging were reported in eight studies. Treated areas included the buttocks (n=4), thighs (n=3), arms or calves (n=1), and abdomen (n=11). For abdominal contouring, mean reductions of fat thickness were 5.5 mm, muscle thickness of 2 mm, and rectus diastasis improvement of 3.0 mm. No studies reported weight change before and after treatment. All studies with patient-reported outcomes report high patient satisfaction. Two studies report marginal or no benefit of treatment. Certain studies failed to report comorbidities or demographic characteristics other than age and sex, which precludes analysis of specific subgroups that may benefit from treatment. Furthermore, certain studies failed to address how missing data or the final study population was analyzed. CONCLUSION This systematic review reports on currently published evidence regarding the efficacy and safety of Emsculpt and Emsculpt NEO for body contouring. High-quality level data reporting with patient-reported outcomes will optimize shared decision-making and informed consent. LEVEL OF EVIDENCE II Therapeutic study. This journal requires that authors assign a level of evidence to each article.

Goldberg DJ. Induction of fat apoptosis by a combination of synchronized radiofrequency and HIFEM technology: Human histology study. J Cosmet Dermatol 2024; 23:812-817. [PMID: 38279191 DOI: 10.1111/jocd.16197] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2023] [Revised: 01/11/2024] [Accepted: 01/15/2024] [Indexed: 01/28/2024]
Abstract
PURPOSE With the growing demand for more effective fat reduction techniques, a combination of synchronized radiofrequency (RF) and HIFEM has been introduced. Preceding studies evidenced the ability of RF+HIFEM to maintain the fat tissue temperature at the levels necessary for adipocyte apoptosis while documenting the induced changes to the fat tissue during the several weeks after the treatment. This study aims to demonstrate the induction of apoptosis by RF+HIFEM technology in the early stages through the assessment of caspase-3 protein, one of the apoptosis-executing proteases. DESIGN In this two-arm, single-center, randomized trial, nine human subjects were enrolled and assigned into two groups, either the active group (N = 6) treated with both RF+HIFEM set at the highest tolerated levels or the sham group (N = 3) treated with 5% of the maximum RF+HIFEM power, serving as a control. All patients were scheduled to undergo one treatment visit of the abdominal area, two follow-up visits at 8 and 24 h, and one safety visit 7 days after the treatment. A punch biopsy (5 mm in diameter, approximately 10 mm in depth) was obtained from the abdominal area at the baseline and consecutive follow-up visits. Samples were fixed, and cut into 5 μm thick slices, and immunohistochemical staining was used to visualize the Caspase-3, revealing the adipocyte nuclei where apoptosis processes are in progress. FINDINGS Documented findings suggest that the temperature threshold of 43-45°C is required to initiate fat apoptosis and consequent reduction in adipocyte number was achieved during the combined treatment with RF+HIFEM. The active group showed an elevated ratio of positively stained nuclei versus all adipocyte nuclei found on the evaluated slices-referred to as the apoptotic index (AI). The AI significantly (p < 0.001) increased at both 8 h (47.01 ± 10.56%) and 24 h (43.58 ± 6.35%) posttreatment. The Sham group showed no significant change in the AI (p > 0.05). No adverse events or side effects related to the treatments were observed. SUMMARY This study supports previously published evidence on fat reduction after RF+HIFEM treatment, documenting the safe initiation of adipocyte programmed cell death posttreatment.

Abstract
Background RZL-012 is a novel cytolytic drug that has shown promise in reducing localized fat deposits in a single treatment session. Objectives To assess the safety and efficacy of injecting RZL-012 to the flanks. Methods A double-blind, placebo-controlled, proof of concept study randomized 12 patients to receive RZL-012 injections in 1 flank and placebo injections in the contralateral flank. After 12 weeks of follow-up, patients could receive RZL-012 in the placebo-treated flank and undergo follow-up for 12 weeks in the open-label phase. Results At 12 weeks, Investigator Global Aesthetic Improvement Scale assessments showed improvement for 90.9% of RZL-012-treated flanks and 0% of placebo-treated flanks (P < .0001), 81.8% of patients were satisfied with the RZL-012-treated flanks, and 9.1% were satisfied with the placebo-treated flanks (P = .0019). Volume reduction measured on 3-dimensional images was a mean 37.27 mL, which was significantly greater than placebo (P = .0052). The product was well tolerated, with no clinically significant trends in laboratory values, electrocardiograms, or vital signs. Pharmacokinetic analyses demonstrated that RZL-012 is quickly absorbed, reaches maximum concentration in approximately 1.67 h, and has a half-life of 9.1 h. The mean maximal concentration of RZL-012 found in the blood was <1 µg/mL. Conclusions RZL-012 is a promising option for injectable fat reduction of the flanks in a single treatment session. The drug was well tolerated in this small patient population, with no concerning safety signals, and it had indications of efficacy. Further research is needed in large Phase 2 studies with robust efficacy measurements to confirm these early findings. Level of Evidence 2

Abstract
BACKGROUND Visceral adipose tissue (VAT), present in the abdominal cavity, oftentimes contributes to an unpleasant aesthetic appearance and can be correlated with serious health issues. High-intensity focused electromagnetic field (HIFEM) technology with synchronized radiofrequency (RF) was recently used for abdominal body shaping through subcutaneous fat reduction and muscle growth. AIM This study aimed to assess the effect of HIFEM + RF technology on VAT tissue. METHODS Data of 16 men and 24 women (22-62 years, 21.2-34.3 kg/cm2 ) from the original study were retrospectively reviewed. All subjects received three 30-min HIFEM + RF abdominal treatments once weekly for three consecutive weeks. The VAT area was measured in the axial plane of MRI scans at two levels: L4-L5 vertebrae and 5 cm above this level. The VAT was identified, segmented, and calculated, yielding total area in square centimeters per scan at both specified levels. RESULTS By thoughtful review of the subject's post-treatment MRI scans, no other changes in the abdominal cavity were found except for VAT. The evaluation showed a VAT reduction of 17.8% (p < 0.001) on average at 3-month follow-up, maintaining the results up to 6 months (-17.3%). Averaging the values obtained from both measured levels, the VAT, occupied an area of 100.2 ± 73.3 cm2 at the baseline. At the 3-month follow-up, the subjects achieved an average reduction of 17.9 cm2 , preserving the results at 6 months (-17.6 ± 17.3 cm). CONCLUSION This retrospective analysis of MRI images objectively documented the effect of HIFEM + RF abdominal therapy on VAT. The data indicates considerable VAT reduction without serious adverse events following the HIFEM + RF procedure.

Abstract
BACKGROUND Noninvasive laser for body fat contouring is a quickly growing field in the cosmetic dermatology. Surgical options carry disadvantages, such as the usage of anesthetics, swelling, pain and long time for recovery, so there is a growing public request for the techniques with fewer side effects and shorter recovery periods. Several new noninvasive body contouring ways have been advanced such as, cryolipolysis radiofrequency energy, suction-massage, high-frequency focused ultrasound, and laser therapy. Noninvasive laser improves the body's appearance by the elimination of excess adipose tissue, specifically in areas in which fat perseveres in spite of diet and exercise. METHODS In this study the efficacy of Endolift laser was evaluated for reduction of excess fat in the arms and under abdomen. Ten patients with excess fat in the arms and under abdomen were enrolled in this study. The patients were treated by Endolift laser in the arms and under abdomen areas. The outcomes were evaluated by two blinded board certified dermatologists and by patients' satisfaction. The circumference of each arm and under abdomen was measured using a flexible tape measure. RESULTS The results showed reduction in the fat and circumference of arms and under abdomen after treatment. The treatment was considered as effective methods with high patient satisfaction. Also no severe adverse effects were reported. CONCLUSION Endolift laser can be a good alternative to surgical body fat contouring due to its efficacy, safety, minimal recovery time, low cost. Also Endolift laser does not require general anesthetics.

Abstract
Background The high-intensity focused electromagnetic field (HIFEM) procedure is an effective method for noninvasive toning and shaping of buttocks. Objectives To investigate and compare the efficacy of simultaneous application of HIFEM procedure with radiofrequency (RF) heating vs HIFEM standalone procedure on the buttocks. Methods Sixty-seven subjects (21-67 years, BMI 16-34 kg/m2) were recruited and divided into two groups. Group A received simultaneous HIFEM + RF therapy, and group B received standalone HIFEM treatments. All participants underwent four 30-minute bilateral treatments on the buttocks. The MRI was used to evaluate the changes in muscle and fat thickness. Results Data of 32 subjects from group A and 31 subjects from group B were reviewed at 1-month follow-up. On average, subjects from group A showed a 31.3% higher increase in muscle thickness, as shown in the MRI evaluation. The gluteal muscle thickness continued to grow and peaked at a 3-month follow-up, wherein 27 patients were evaluated in each group (n = 54). Group A showed on average +24.7% increase (gluteus maximus +8.5 ± 1.9 mm, medius +6.0 ± 1.1 mm, minimus +2.9 ± 0.8 mm), while group B exhibited only +15.9% increase in muscle thickness (gluteus maximus +5.2 ± 1.1 mm, medius +3.6 ± 1.0 mm, minimus +1.6 ± 0.4 mm). On average, group A showed a 35.6% higher growth in muscle thickness. Treatments were safe and comfortable with high satisfaction rates. No adverse event was reported throughout the study. Conclusions Our results suggest that simultaneous use of HIFEM + RF is safe and significantly more effective for gluteal contouring than the HIFEM procedure alone. Level of Evidence 2

Abstract
BACKGROUND Radiofrequency and HIFEM have been used as standalone modalities in body contouring. The novel device allows their synchronous emission simultaneously in a single applicator. OBJECTIVES This prelusive trial aims to investigate the safety and efficacy of such treatment when used on multiple body parts on the same day for a full-body remodeling. METHODS Three female subjects (21.0 ± 2.0 years) underwent 4 treatment sessions. The treatment was applied to the abdomen, saddlebags, inner thighs, and buttocks, during each visit, lasting 30 min for each site. The outcomes were assessed through examination of MRI images acquired at baseline and 3 months post-treatment. Fat and muscle thickness were measured at predefined locations. Weight and waist, hip, and thigh circumference records along with digital photographs were also taken. RESULTS Fat thickness measurement showed a reduction of 17.57 ± 3.22 mm in the saddlebag region, 12.43 ± 1.93 mm in inner thighs, and 10.65 ± 1.26 mm in the abdomen. The fat in the buttock region showed negligible changes. The muscle thickness increased on average by 2.98 ± 0.60 mm for rectus abdominis and 7.42 ± 1.56 mm for gluteus maximus. The circumferential reduction was also observed on the waist (7.83 ± 2.25 cm), at the level of outer thighs (2.83 ± 1.53 cm), and inner thighs (3.58 ± 1.84 cm). Digital photographs showed noticeable improvement in the overall body appearance. The treatments were safe, and no side effects were noted. CONCLUSION The preliminary outcomes indicate that the procedure delivering HIFEM and RF simultaneously on multiple body areas on the same day could be an effective and comfortable treatment for fat reduction on multiple body parts, thickening of underlying muscles, and overall improved aesthetic appearance.

Abstract
BACKGROUND Inevitable signs of aging are especially noticeable in middle to elder age when stretch marks, loose skin, cellulite, and body-contour changes naturally appear. AIMS To verify efficacy of high-intensity focused electromagnetic field (HIFEM), radiofrequency (RF), and Targeted Pressure Energy (TPE) combination treatment to address unfavorable changes in skin, fat, and muscle tissue. METHODS The device simultaneously emitting monopolar RF and TPE energies was consecutively combined with simultaneous HIFEM+RF procedure in 32 subjects (21-64 years, 17.4-33.5 kg/m2 ) for treatment of thighs (N = 15; back, inner, or front), buttocks/saddlebags (N = 7), abdomen (N = 8), and upper arms (N = 2). All patients underwent four weekly, combined treatments of 30-min HIFEM+RF procedure followed by 15-30 min RF+TPE, depending on treatment area. Circumferential measurements, digital photographs, subject satisfaction, and comfort questionnaires were assessed up to 3-months post-treatment. RESULTS Majority of participants found treatments comfortable, no adverse events occurred. Subjects showed substantial improvement in all treated areas from 1-month follow-up. Combination of HIFEM+RF, monopolar RF, and TPE resulted in significant circumference decrease. Generally, more pronounced results were seen at 3 months when subjects showed -5.2 cm on abdomen, -3.0 cm on thighs, and -5.5 cm on saddlebags, respectively. Ninety-four percent of subjects were satisfied with treatment results, most noticed improvement in cellulite, skin laxity, and muscle definition. CONCLUSIONS Results showed high patient satisfaction and efficacy in improving body contour and skin quality. Combining simultaneous HIFEM+RF procedure with simultaneous monopolar RF+TPE treatments considerably enhanced body contour and skin tissue. The procedure proved versatile and may effectively treat multiple body parts.

Abstract
BACKGROUND In 2018, the first device to use high-intensity focused electromagnetic (HIFEM) technology to non-invasively build muscle was brought to market. Even more recently, the first HIFEM and radiofrequency combination device designed to both build muscle and eliminate fat cells came into use (HIFEM+). In view of the increase in recently published original data pertaining to HIFEM, an advisory board recently convened to discuss the group's clinical experiences with this technology. AIM Communicate an advisory group's recommendations for the current use of HIFEM+ technology for aesthetic indications. METHODS An advisory board meeting to discuss challenges and opportunities for HIFEM devices in aesthetic medicine took place in November 2020, via remote conference. The expert advisory board consisted of a group of senior aesthetic physicians regularly treating patients with non-invasive body contouring devices. A narrative review of the literature and key recommendations from the meeting are presented herein. RESULTS To date, the combined results of several clinical studies (including over 500 patients and 30 investigators) support that patients treated with HIFEM+ experience on average, 30% less fat, 25% more muscle, 19% reduction in abdominal separation and up to 5.9 cm reduction in waist circumference. Moreover, HIFEM+ induces a 30% increase in satellite cell content, which is similar to the 36% increase observed following twelve weeks of exercise. CONCLUSIONS The advisory board unanimously agreed on several messages related to HIFEM technology, including that the pairing of HIFEM and radiofrequency (HIFEM+) enables a higher intensity of muscle stimulation and lipolysis, compared to HIFEM alone.
