Laser scar removal is useful and is currently the most effective way to treat scars with remarkable results. Laser scar removal is to use the instantaneous generation of high heat to act on the affected area subcutaneously, turning scar tissue from particles into powder, which is absorbed and eliminated by the cells on the skin surface, thus improving the scars from deep to shallow until they disappear. This treatment method is effective for protruding scars and good for depressed scars with area within 2cm and not deep trauma. For those with large area and deep trauma, only laser treatment is not effective and needs to be combined with local subcutaneous fat injection to fill the depressed area so that the scars can be removed. It is normal that the local skin will be red and swollen and scabbed after laser treatment, take anti-inflammatory drugs orally for 3-7 days continuously, let the scab formed fall off by itself and do not use hands to buckle it, otherwise it will affect its recovery, within three months of laser scar removal, you need to pay attention to sun protection and avoid spicy, seafood and other stimulating foods, otherwise it will affect the recovery.
