Laser treatments are effective and widely used methods for a broad range of dermatological and cosmetic concerns. They can operate on similar principles to treatments like chemical peels, which facilitate the shedding or renewal of the skin's upper layers. Lasers use controlled thermal energy to target problematic areas of the skin, thereby improving conditions such as spots, acne scars, fine wrinkles, and lines. The treatment is carried out with devices of different wavelengths, chosen according to the specific problem being addressed. Lasers are also successfully used with various types for specific purposes like tattoo removal and hair removal (epilation).
