Picking off the scabs after laser surgery on the face may leave scars, and in serious cases, may cause wound infection. Generally speaking, the time for the scabs to fall off automatically after laser surgery is 7-10 days. If the scabs are picked off by external force at an early stage, it may cause scars and higher chances of infection, but if the scabs fall off at a later stage, the effect will be relatively mild. After the scabs fall off, there is no need to be too nervous, do a good job of cleaning and physical sun protection (go out and wear hats, masks, umbrellas and other protection), keep a light diet, do not use acids or products containing irritating ingredients, strengthen the moisturizing, and if necessary, topical application of epidermal growth factor gel. If you notice persistent redness, swelling, or oozing where the scabs have fallen off, an infection may have occurred, and you must seek treatment at a nearby dermatologist as soon as possible.
