How effective is laser treatment for acne scars?

In general, the effect of laser treatment for acne scars is relatively good. Laser treatments for acne scars usually employ fractional laser technology, such as carbon dioxide (CO2) lasers or erbium lasers. These lasers can precisely penetrate the epidermis to reach the dermis, creating microscopic zones of thermal damage that stimulate the skin's natural healing process, promoting the regeneration of collagen and elastic fibers, thereby filling in acne scars.

The effectiveness of laser treatment for acne scars varies from person to person, depending on the depth and number of scars, as well as individual differences. Generally, after multiple sessions, acne scars can be significantly improved, restoring facial aesthetics. However, laser treatment can also be somewhat irritating and may cause localized redness, swelling, heat, or discomfort post-treatment, so it should be performed under the guidance of a qualified physician.

Prior to treatment, the physician will assess the patient's skin condition to determine the appropriate type of laser and parameters. Local anesthesia may be required during treatment to minimize discomfort. After treatment, redness, mild pain, and crusting may occur, which are normal reactions and typically subside within a few days to a week. It is recommended to consult a qualified physician to develop a personalized treatment plan based on individual circumstances.
