An ablative laser is a type of laser used in various medical and cosmetic procedures to remove layers of skin or tissue. It works by emitting concentrated light energy that vaporizes the targeted area, promoting skin rejuvenation and healing. This technique is commonly used for treating scars, wrinkles, and other skin imperfections. Ablative lasers can be classified into two main types: carbon dioxide (CO2) lasers and erbium lasers. CO2 lasers penetrate deeper into the skin, making them effective for more severe skin issues, while erbium lasers are gentler and often used for milder treatments. Both types help stimulate collagen production, enhancing skin texture and appearance.
