The time it takes for the scabs to fall off your face after acid resurfacing is related to the concentration of the acid used and the condition of the recipient’s skin, and can take anywhere from 3 days to 3 weeks. It is normal for scabs to appear after acid resurfacing. They are the outer layer (epidermis) that is slowly removed after the acid is applied to the skin, and the duration of the scabs varies depending on the depth of the exfoliation. Mild peeling generally lasts 3 days to 7 days, moderate peeling lasts 1 week to 2 weeks, and severe peeling takes 2 weeks to 3 weeks for the scabs to fall off. In addition to observing the scabs after peeling, you also need to pay attention to the formation of blisters, persistent pain, herpes infection, etc., and need to go to the hospital in a timely manner to see a doctor, while paying attention to strict sunscreen, even if the scabs fall off completely, you still need to apply sunscreen and then go out.
