1. Evaluation of a Novel Bimodal-Approach Radiofrequency Device for Lower Facial Tightening in Southeast Asian Patients: An Open-Label Prospective Study.
In a prospective open-label study (n=26; 23 completed), a sequential monopolar+bipolar RF device achieved significant improvements in lower facial laxity with objective reductions in nasolabial fold metrics and high 6‑month satisfaction. Adverse events were minor and transient. Trial registration was reported.
Impact: Introduces and clinically evaluates a bimodal RF delivery paradigm with objective imaging outcomes and trial registration, supporting evidence-based adoption in aesthetic practice.
Clinical Implications: Supports offering single-session bimodal RF tightening to appropriately selected patients, with counseling on expected 6‑month gains and transient erythema/edema; informs device choice and post-market evidence needs.
Key Findings
- 47.83% achieved marked improvement (51–75%) at 6 months on a 6-point global improvement scale.
- Facial laxity ratings improved significantly at 1, 3, and 6 months versus baseline (p<0.001).
- 3D Antera imaging showed significant reductions in nasolabial fold cross-sectional area (p=0.02) and wrinkle width (p=0.01).
- Approximately 78% reported high satisfaction at 6 months; adverse events were minor and transient (erythema 96.15%, edema 61.53%).
Methodological Strengths
- Prospective design with predefined endpoints and multiple follow-up timepoints (1, 3, 6 months).
- Objective imaging (3D Antera, VISIA) and validated clinical rating scales.
- Registered clinical trial with appropriate non-parametric and mixed-effects analyses.
Limitations
- Single-arm open-label study without a control or comparator device.
- Modest sample size and 6-month follow-up may limit generalizability and durability assessment.
Future Directions: Randomized controlled trials versus standard RF modalities, longer-term (≥12 months) durability studies, and subgroup analyses across skin types and ages.
BACKGROUND: Radiofrequency (RF) devices are employed for noninvasive facial rejuvenation. A novel bimodal RF system delivers monopolar and bipolar energy sequentially within a single shot to enhance efficacy and safety. OBJECTIVES: To evaluate the safety and efficacy of a bimodal-RF device, DENSITY Noir (Jeisys Med Inc., Seoul, Republic of Korea), for the treatment of lower facial laxity. METHODS: This prospective, open-label clinical study enrolled 26 adults (n = 26; 30-60 years) with mild-to-moderate lower facial laxity. All participants received a single RF treatment session with DENSITY Noir. Outcomes were assessed using investigator and participant global assessments, the Facial Laxity Rating Scale, and 3D Antera imaging for nasolabial fold parameters, together with texture and brown spot measured by VISIA. Safety and tolerability were monitored throughout the study. Statistical analyses included Friedman and Wilcoxon tests, marginal homogeneity tests, and linear mixed-effects model tests. RESULTS: Twenty-three (n = 23) participants completed follow-up. Nearly half (47.83%) achieved marked improvement (51%-75%) on the 6-point global improvement scale at 6 months. Facial laxity ratings significantly improved at 1, 3, and 6 months vs. baseline (p < 0.001). Antera analysis confirmed significant reductions in nasolabial fold cross-sectional area (baseline: 41.94; 1 month: 38.87; 3 months: 39.63; 6 months: 35.72; p = 0.02) and wrinkle width (baseline: 1.98 mm; 6 months: 1.85 mm; p = 0.01). About 78% of participants reported high satisfaction at 6 months. Adverse effects included transient erythema (96.15%), edema (61.53%), and mild procedural pain; all adverse events were minor, transient, and self-limiting. CONCLUSIONS: DENSITY Noir was associated with significant improvement in lower facial laxity with a favorable safety and tolerability profile in this cohort. Further controlled studies are warranted to confirm efficacy and durability. TRIAL REGISTRATION: ClinicalTrials.gov identifier: TCTR20250924004.
2. Evaluation of Efficacy and Safety of Radiofrequency Heating With Targeted Ultrasound and Active Cooling Technology for Localized Fat Reduction.
In 23 subjects receiving four sessions of RF plus targeted ultrasound with active cooling, ultrasound-measured fat thickness decreased by 16.3% at 1 month and 22.5% at 3–6 months (p<.0005), corroborated by calipers. Seventy-one percent reported improvement at 6 months, and treatments were safe with epidermal protection.
Impact: Demonstrates quantifiable, durable fat-layer reduction using combined RF–ultrasound with active cooling, addressing depth and safety limitations of prior noninvasive devices.
Clinical Implications: Supports offering a noninvasive body-contouring option with clear counseling on expected percentage fat-layer reductions over 1–6 months and high satisfaction; underscores the role of active epidermal cooling in mitigating superficial burns.
Key Findings
- Ultrasound-measured fat thickness decreased by 16.3% at 1 month and 22.5% at 3 and 6 months (p<.0005).
- Caliper measurements showed 28.4%, 32.9%, and 42.5% reductions at 1, 3, and 6 months, respectively (p<.0001).
- 71.4% of participants reported improvement at 6 months, with overall treatments deemed safe with epidermal protection.
Methodological Strengths
- Prospective design with predefined multi-timepoint assessments up to 6 months.
- Objective quantification with both ultrasound and caliper measurements corroborating effects.
Limitations
- Single-arm, small-sample study without a comparator device or sham control.
- Device-specific parameters and population characteristics may limit generalizability.
Future Directions: Conduct randomized controlled trials with sham or active comparators, expand to diverse BMI/skin types, and assess histologic correlates and long-term durability (>12 months).
BACKGROUND: Noninvasive targeted adipose reduction is highly sought after, with many devices using radiofrequency. Without adequate surface cooling, these treatments may not reach optimal depths and superficial burns can result. OBJECTIVE: To evaluate fat reduction, safety, and patient satisfaction with a device combining radiofrequency and targeted ultrasound with superficial active cooling which heats localized adipose tissue while protecting the epidermis. MATERIALS AND METHODS: Twenty-three subjects with localized fat underwent 4 treatments of radiofrequency with targeted ultrasound and active cooling. Pre- and post-treatment evaluations included photographs and measurements using a caliper and ultrasound. Subjects also completed satisfaction and comfort questionnaires. Data were collected at baseline, after the final session, and 1, 3, and 6 months post-treatment. RESULTS: Ultrasound showed a gradual fat thickness reduction: -16.3% at 1 month, and -22.5% at 3 and 6 months (p < .0005). Caliper measurements confirmed this trend: -28.4% at 1 month, -32.9% at 3 months, and -42.5% at 6 months (p < .0001). Patient satisfaction was high, with 71.4% reporting improvement at 6 months. CONCLUSION: Combining radiofrequency and ultrasound with active cooling effectively reduces adipose tissue while protecting the superficial tissues. Treatments were effective, had a high satisfaction rate, and were shown to be safe.
3. Body dysmorphic disorder in Lebanese dermatology patients: prevalence and correlates of depression, anxiety, stress, and trauma in a multitraumatized population.
In a trauma-exposed dermatology population, body dysmorphic disorder (BDD) prevalence was 7.6% and strongly correlated with depression, anxiety, stress, and PTSD symptoms. Findings position dermatology clinics as key venues for BDD screening and early detection in high-risk groups.
Impact: Highlights a clinically significant BDD burden in dermatology patients within a multitraumatized context, emphasizing mental health screening relevance for cosmetic decision-making and risk mitigation.
Clinical Implications: Integrate brief BDD screening and mental health referral pathways into dermatology and cosmetic clinics to prevent iatrogenic harm and optimize patient selection and satisfaction.
Key Findings
- BDD prevalence was 7.6% among Lebanese dermatology patients in a chronically trauma-exposed setting.
- BDD was strongly associated with depression, anxiety, stress, and post-traumatic stress symptoms.
- Dermatology clinics represent an important opportunity for BDD screening and early detection in multitraumatized populations.
Methodological Strengths
- Focus on a multitraumatized population relevant to psychodermatology and cosmetic decision-making.
- Concurrent assessment of multiple psychopathology dimensions alongside BDD status.
Limitations
- Cross-sectional observational design limits causal inference.
- Sampling frame and measurement tools are not detailed here, and generalizability may be limited.
Future Directions: Develop and validate brief BDD screening tools tailored to dermatology/cosmetic settings; conduct longitudinal studies to evaluate outcomes of integrated screening-referral pathways.
