Fractional CO2 laser machines are used for skin resurfacing, scar repair and wrinkle reduction. The machine emits tiny beams of light that cause controlled damage to the skin, stimulating the body's natural healing process and boosting collagen production. This improves skin tone, texture and firmness. Fractional carbon dioxide lasers are commonly used to treat acne scars, sun damage, age spots and other signs of aging. It can also be used for overall skin rejuvenation and reducing the appearance of fine lines and wrinkles.
