Radio frequency (RF) energy treatment is a modern technology used for non-surgical tightening of the early signs of loose or sagging skin. Pure RF energy alone is primarily used to treat skin laxity by tightening. Radio waves penetrate the patient’s outer skin layers, delivering heat energy to the deep dermal layers. This heat stimulates collagen production and, in turn, triggers tissue contraction. The overall result is tighter, brighter skin and a significant reduction in sags and wrinkles.
