CO₂ laser is a fractional ablative laser treatment designed for intensive skin resurfacing and regeneration. It is used to improve wrinkles, scars, pigmentation, uneven skin texture and signs of photoaging, as well as selected aesthetic and dermatological indications. By acting on deeper layers of the skin, it stimulates regeneration and collagen production, making the skin smoother, firmer and more even. The number of treatments depends on the indication and protocol intensity, with 1 to 3 treatments most commonly recommended.
