This process triggers the body's natural healing process, leading to increased collagen production, improved skin tone and texture, and a reduction in wrinkles and scars. The fractional RF machine is equipped with a number of needles, which penetrate the skin at varying depths to create a controlled pattern of micro-injuries.
