Chemical peels remove damaged outer layers of skin on the face to smooth texture, reduce scarring, and remove blemishes to produce healthy, glowing skin. Chemical peels can range from mild to strong and usually consist of alphahydroxy acids (AHAs) or trichloroacetic acid (TCA) - formula strengths are tailored to each patient.
Types of Chemical Peels
AHAs are the gentlest of the three types of chemical peel. They consist of a group of glycolic, lactic and fruit acids that smooth and brighten skin by treating fine wrinkles, dryness, uneven pigmentation and acne. AHAs are typically applied once a week, or may be mixed in a milder concentration with a cream or cleanser to be used daily; treatment takes 10 minutes or less. Patients may choose AHAs if they do not want the lengthy recovery time of a TCA peel. Occasionally AHAs, Retin-A (a prescription medication containing Vitamin A) or hydroquinone (a bleach solution) are used to thin the skin and even its tone as a pre-treatment for TCA peels.
TCAs are commonly used for medium-depth peeling (though depth is adjustable) to treat fine surface wrinkles, superficial blemishes and pigment problems, sometimes in combination with AHAs. TCAs are the preferred chemical solution for darker-skinned patients and may be used on the neck and other areas of the body. Multiple treatments may be required.
