The use of hybrid radiofrequency device for the treatment of rhytides and lax skin.

摘要

BACKGROUND: Recently, radiofrequency (RF) devices have been introduced and commercialized for nonablative procedures in dermatology and plastic surgery for the treatment of age-related rhytides and lax skin. OBJECTIVE: The objective was to assess the efficacy and safety of a novel RF device (Accent, Alma Lasers, Ltd, Caesarea, Israel) for the treatment of rhytides and lax skin. METHODS AND MATERIALS: Sixteen female patients (age range, 29-66 years; mean, 47+/-6 years; skin phototypes II to IV) were treated with Accent system. Patients were treated on the chin (n=5), forehead (n=8), cheeks (n=12), jowl lines (n=9), periorbital area (n=7), marionette line (n=3), and nasolabial folds (n=6) for wrinkles (n=27 cases) and skin laxity (n=23 cases). Patients received two to six treatments (mean, 4.3+/-1.1), with the time interval of 2 to 3 weeks. Photographs were assessed 1 month after the last treatment. RESULTS For wrinkles and skin laxity, in 5 patients (42%), the cheeks (n=12) scored 51% to 75% (significant improvement), and 2 patients (17%), 76% to 100% (excellent improvement). For the jowl lines (n=9), 4 patients (44%) scored 51% to 75% (significant improvement), and 1 patient scored 76% to 100% (excellent improvement) for lax skin. For wrinkles on the periorbital (n=7) and forehead areas (n=8), three patients (37%) scored 51% to 75% (significant improvement). CONCLUSION: The Accent system is an effective and safe modality for the improvement of age-related rhytides and lax skin.
