Radio Frequency Therapy is a non-surgical means of “reshaping” the skin and body to reduce fine lines, wrinkles, sagging skin, and even cellulite. RF therapy works by using energy waves to heat the deep layer of your skin known as your dermis. This heat stimulates the production of collagen to help improve signs of wrinkles and sagging skin. Research has shown that RF therapy is usually safe and can be effective at treating mild or moderate signs of aging.
