All acid peels work best when the skin has't been cleansed with overly alkaline products, which contain soap. If you've been using products that contain sodium lauryl sulfate or sodium laureth sulfate, then they have soap in them. You can remedy the topical problem by using a gentle facial scrub 24 hours before you peel and switch to a non-soap based cleanser.

One should always do a patch-test before applying a chemical peel. Do the test on a sensitive area, such as the inside of your wrist or the side of your neck. Test an areas about the size of a quarter then wait 24 hours to see if you have any adverse reaction.
