After the treatment, the skin may become red and take on a tingling sensation. After about 2 to 3 hours this will subside and there will be almost no noticeable effects. It is possible that the skin peels on day 3 or 4 after treatment. Usually this goes away after about 7 days. The skin may still be a bit drier in structure, but with good care in the form of hydration, the skin will recover faster.
