Dual-mode Sequential Radiofrequency in Challenging Skin Types: Case Reports in Atopic-prone and Previously Treated Patients.

Facial laxity is a major aesthetic concern, often managed through energy-based skin-tightening devices. However, safety considerations arise when treating patients with atopic dermatitis (AD), due to barrier dysfunction, and in those with prior aesthetic procedures, where synergistic effects and risks remain unclear. We aimed to assess the safety and efficacy of a dual-mode radiofrequency (RF) device in 2 challenging clinical contexts: atopic-prone skin and previously treated skin. Two female patients underwent single-session treatment with a dual-mode monopolar-bipolar RF system (DENSITY, Jeisys Medical Inc., Seoul, Republic of Korea), with integrated contact cooling. Outcomes were assessed using standardized photography, patient-reported improvement, and monitoring for adverse events. Both patients exhibited clinically significant skin tightening, improved skin texture, and reduced fine lines. The patient with AD tolerated treatment without flares or complications. The previously treated patient (Ultherapy, botulinum toxin, poly-D,L-lactic acid boosters) reported complementary benefits beyond those achieved with earlier procedures. Both rated satisfaction as 4 out of 5. Treatment-related discomfort was reported as 6 out of 10 (AD patient) and 5 out of 10 (previously treated patient). Dual-mode RF seems to be safe and effective for addressing facial laxity in patients with atopic-prone skin and in those who have undergone prior aesthetic treatments. It may serve as a valuable adjunct or maintenance modality in facial rejuvenation.
