Radiofrequency (RF) therapy, a popular beauty treatment, uses energy levels between visible light and infrared, but higher than extremely low frequency (ELF) radiation. RF works by heating the skin to stimulate collagen production, reducing wrinkles and sagging. Extensive research confirms its safety and effectiveness, offering skin tightening benefits without downtime. It effectively targets loose or sagging skin on areas like the face, abdomen, arms, and legs.
