The alpha hydroxyacid used most commonly for peels is gylocic acid. Unlike other chemical peels, alpha hydroxyacids are not toxic to the skin. The most common side effect after a peel is brown discoloration of the skin. This is usually reversible but can rarely be permanent. This side effect usually occurs only in those who have had sun exposure after a peel.
Peels can cause persistent redness of the skin.
If you get cold sores, a peel can cause them to flare. This can be prevented by taking a prescription drug named Acyclovir. At least three to four weeks before your first peel, stop using Retin-A and exfoliating sponges. All forms of hair removal should be stopped at least three to four weeks before your peel. Come to the office with a fully cleansed face.
