In a chemical peel, a chemical solution is applied to the skin and allowed to soak in. Over the next 1 to 14 days, depending on how deeply the chemical penetrated the skin, the skin peels off.This procedure destroys parts of the skin in a controlled way so that new skin can grow in its place. deep peel causes a deeper second-degree burn of the skin. Skin regrowth takes between 10 to 14 days after a deep peel. The skin remains extremely red for 3 weeks, up to 2 months for some people. Most people take about 2 weeks off from work.
