Question: I live in Arizona where the sun shines every day. Unfortunately that means I need to load up on the sun screen since I have a family history of skin cancer. I recently read that a chemical peel may be effective in removing pre-cancerous cells. Is this true?
Answer: Chemical peels are mostly acidic solutions that help exfoliate the skin. The type depends on the level of penetration into the skin (superficial to deep). If the pre-cancerous lesion is very superficial, certain medium to deep typechemical peels will be of some benefit.
