Clinical Evaluation of a Novel Dual-Mode Radiofrequency Device for Facial Laxity: A Case Series.

[PURPOSE] Facial aging, characterized by skin laxity and the formation of wrinkles, is primarily attributed to collagen degradation and dermal thinning. Although ablative laser therapies have demonstrated efficacy in addressing these concerns, their application is often limited by prolonged downtime and the risk of pigmentary alterations, particularly in individuals with darker skin types. Radiofrequency (RF) technology offers a non-invasive, chromophore-independent alternative for skin tightening and rejuvenation. This case series aims to assess the clinical efficacy, safety profile, and patient-reported satisfaction associated with the use of a novel dual-mode RF device in the management of facial skin laxity.

[PATIENTS AND METHODS] Five adult patients with Fitzpatrick Skin Type IV and clinically evident signs of facial photoaging underwent a single treatment session using the DENSITY RF platform, which integrates monopolar and bipolar energy delivery through High F-tip. Each procedure involved 10 to 12 uniform passes over the entire face, utilizing continuous contact cooling. No topical or systemic anesthesia was administered.

[RESULTS] All patients demonstrated measurable improvements in skin firmness, textural smoothness, and facial contouring. Marked reductions in wrinkle surface area and pore visibility were observed. Aesthetic enhancement scores ranged from 3 to 5 (on a 5-point scale), with high levels of patient satisfaction and minimal procedural discomfort (VAS score: 2-3/10). Three patients reported visible brow-lifting effects. No adverse effects or pigmentary changes were reported.

[CONCLUSION] The DENSITY dual-mode RF system is a safe, well-tolerated, and effective non-invasive option for treating facial skin laxity in individuals with darker skin tones. It offers a compelling alternative for single-session rejuvenation with minimal recovery time and high patient satisfaction.
