A skin peel or chemical peel involves a chemical solution being applied to the skin causing the dead skin to slough off and eventually peel. The regenerated and resurfaced skin is smoother, with better texture and less lines than the old skin. A chemical peel works by inducing a controlled wound to the skin, removing the top layers of the skin causing collagen remodelling. Peels can be used to treat sun damage, wrinkles fine lines, texture, skin pigmentation and the general appearance of the skin.

Chemical peels range from the least invasive to the most invasive, this relates to their strength, which will determine how deep they will peel. The least invasive peels also have the least risks and complications.
