Using carbon dioxide laser is suitable for removing wrinkles, scars, fine lines on the face and dents left by acne, but not for scalding scars. Laser therapy can smooth fine lines and scars and make skin or scars smoother. Because of the high intensity of carbon dioxide laser, it directly radiates heat energy to the skin, which makes the subcutaneous tissues such as collagen compact and makes the skin rejuvenate. Huainan Hanmei Plastic Surgery Network wants to reduce fine lines on the face and even remove uneven scars. Laser peeling is much more important than fruit acid peeling.
