Superficial peels are the mildest type of chemical peel. They can be used on all skin types. In most cases, they use liquid containing a mild (dilute) acid, most often glycolic acid. Dry ice (solid carbon dioxide) is sometimes used. Medium peels soak deeper into the skin than superficial peels do.

This is typically harmless and goes away within a few days, but it can be very uncomfortable. Many chemical peels include a healing kit that covers one's skin in antioxidants and botanical extracts.
