ActiveFX™ fractional laser treatment uses a high-energy laser to create thousands of tiny wounds in your skin while heating the deeper layers of your skin. The laser is divided into many tiny beams of light, which help treat a small area of skin at a time. This skin treatment only targets areas that require treatment, leaving the surrounding skin untouched. Microscopic wounds created by the laser heal naturally and stimulate collagen production in the area, which helps rejuvenate and improve skin texture.
