Reactions to chemical peels are similar to sunburn. The recovery time is dependant on the depth of the peel. After any peel, it is very important that the skin be protected from the sun.
The superficial peels are usually done several times over the course of several months while the deeper peels usually only need to be performed once to achieve the desired effect. Regardless of the technique, you will likely need repeat treatments in the future.
With good sun protection and depending on the depth of the peel, results can last months to several years. Generally, the deeper peels have a more long lasting effect.
