A Phenol peel is a very strong type of peel.  It is generally used on deep wrinkles and severly aged skin.  Recovery times with a phenol peel are usually the longest of any of the other peels.  Sometimes a week or longer is required and is usually used on the face.  The results with a phenol peel are similar to those of CO2 laser resurfacing.

Phenol peels work by removing the upper skin layer, going into the epidermis.  When healed, you have younger looking collagen and elastic fibers and smooth skin.
