Abstract

This randomized, blinded, quantitative assessment using a validated grading scale of skin laxity improvement from the gold standard treatment, the surgical face-lift, and comparative analysis to a novel, minimally invasive FRF treatment has demonstrated 49% improvement in skin laxity relative to baseline for the surgical face-lift, compared with 16% for FRF. The surgical face-lift resulted in a mean 1.20-grade improvement on the 4-point laxity grading scale. In comparison, a single, minimally invasive FRF treatment demonstrated a 0.44-laxity grade improvement, or 37% that of the surgical face-lift, without the adverse effects and complications of surgical procedures. This study provides a basis for quantifying cosmetic outcomes from novel treatments with comparative analysis to the gold standard. It also suggests that minimally invasive FRF treatment may provide an important nonsurgical option for the treatment of facial skin laxity.
