Abstract
BACKGROUND: To date, no studies compared curative effects of thermal lesions in deep and superficial dermal layers in the same patient (face-split study).
OBJECTIVE: To evaluate skin laxity effects of microneedle fractional radiofrequency induced thermal lesions in different dermal layers.
METHODS AND MATERIALS: 13 patients underwent three sessions of a randomized face-split microneedle fractional radiofrequency system (MFRS) treatment of deep dermal and superficial dermal layer. Skin laxity changes were evaluated objectively (digital images, 2 independent experts) and subjectively (patients' satisfaction numerical rating).
RESULTS: 12 of 13 subjects completed a course of 3 treatments and a 1-year follow-up. Improvement of nasolabial grooves in deep dermal approach was significantly better than the superficial at 3 months (P=.0002) and 12 months (P=.0057) follow up. Effects on infraorbital rhytides were only slightly better (P=.3531).
CONCLUSION: Microneedle fractional radiofrequency system (MFRS) is an effective method to improve skin laxity. Thermal lesion approach seems to provide better outcomes when applied to deep dermal layers. It is necessary to consider the skin thickness of different facial region when choosing the treatment depth.
