Chemical Peels

Chemical peels remove damaged outer layers of skin on the face to smooth texture, reduce scarring, and remove blemishes to produce healthy, glowing and youthful skin. There are three types of chemical peels, ranging from mild to strong – alphahydroxy acids (AHAs), trichloroacetic acid (TCA) and phenol – and formula strengths are tailored to each patient. Chemical peels performed at our Beverly Hills or Los Angeles facilities can be combined with other procedures such as facelifts for a younger look. These noninvasive procedures may be covered by insurance if they are performed for medical rather than cosmetic reasons.

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 phenol or 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. Results are often less impressive and do not last as long as with phenol peels, and multiple treatments may be required, but treatments only last 10-15 minutes and recovery time is shorter.

Phenol, the strongest chemical peel, treats deeper skin problems such as coarse facial wrinkles, pre-cancerous growths, and areas of blotchy or damaged skin caused by sun exposure, aging or birth-control pills. Because phenol can lighten skin where it is applied, the patient’s natural pigmentation is a factor in determining eligibility. Phenol is used only on the face, as it may cause scarring elsewhere. Full-facial treatment can last an hour or two and recovery can take a few months, with possible permanent skin lightening and removal of freckles.

The Procedure

Chemical peels may be performed in one of our two California outpatient facilities. Anesthesia is not required because phenol and TCAs act as an anesthetic while AHAs produces only a slight stinging, though you may be given a sedative.

In an AHA peel, the skin is cleaned and the solution applied; there is no need for “after-peel” ointment or covering. During TCA and phenol peels, the skin is cleansed and solution is applied, which may cause a brief stinging sensation. Petroleum jelly or a waterproof adhesive tape may be put on the skin following a phenol treatment.

After the Procedure

AHA peels can cause temporary stinging, redness, irritation and flaking or crusting. Phenol and TCA peels can result in tingling or throbbing, reddened skin, a crust or scab, and significant swelling which lasts about a week, depending on the strength of the peel used. With phenol, your eyes may even be swollen shut at first and you may be put on a liquid diet and advised not to talk very much. Any tape used is removed after a day or two. All procedures require adequate sun protection for your new skin.

All three treatment types carry potential risks such as infection and scarring. In addition to the after-effects listed above, TCA peels may produce some unintended color changes in the skin, while phenol peels may reduce or eliminate the new skin’s ability to make pigment evenly or at all, thus causing a lighter or uneven skin tone that must be protected from sunlight.
