Chemical peels are not considered bleaching. The purpose of a chemical is to improve skin tone, texture and wrinkles, while also reducing hyperpigmentation. It works as a more intense exfoliant, causing the top layers of skin to "peel" off while producing newer, fresh looking skin from below. It is not to strip the skin of its natural pigmentation, but removes some of the dead and damaged skin from the top. As for side effects, it can depend on the strength of the peel used. Generally, the stronger the peel is, the more intense the recovery is. That being said, stronger peels lead to better results. Most people will experience some redness and heat. There can be swelling. Some people will have intense peeling while others may not. Everyone's skin type is different so not all skin reacts the same. As for long term side effects, there are not really many. It is possible to have a bad reaction which may lead to blistering or potential scarring, however it is uncommon. We always recommend seeing a professional so they can provide you with an assessment and the best recommendations for treatment.
