Hi. Greetings. Chemical Peeling is safe as long as done by a qualified dermatologist. Don't worry. It doesn't make changes in sensitivity of skin permanently. It's basically a process of rejuvenation of skin. However, it's better to avoid direct sun light in the first forty eight hours after a Peel. And adequate regular use of sunscreen must continue. Hope this helps. Warm regards Dr Govind Suresh Mittal.
