Trichloroacetic acid (TCA) can be used in many concentrations, but most commonly for medium-depth peeling. Fine surface wrinkles, superficial blemishes and pigment problems are commonly treated with TCA. More than one TCA peel may be needed to achieve the desired result.
Compared to a phenol peel, the results of a TCA peel are less dramatic but the downtime is reduced. With a TCA peel, your healed skin will be able to produce pigment as always; the peel will not bleach the skin. However, TCA-peel patients are advised to avoid sun exposure for several months after treatment to protect the newly formed layers of skin. Even though TCA is milder than phenol, it may also produce some unintended color changes in the skin.
Benefits of the TCA Peel:
- Smoothes out fine surface wrinkles
- Removes superficial blemishes
- Corrects pigment problems
- Can be used on neck or other body areas
- Treatment takes only 10-15 minutes
- Preferred for darker-skinned patients
- Peel depth can be adjusted
- Healing is usually quick, much quicker than with a phenol peel
The TCA Chemical Peel Procedure
Typically, the skin is first thoroughly cleansed. Then the TCA solution is applied. You may feel a stinging sensation as the peel solution is applied, but this feeling will quickly pass.
A full-face TCA peel usually takes no more than 15 minutes. Two or more TCA peels may be needed to obtain the desired result, and those may be spaced out over several months. Mild TCA peels may be repeated as often as every month.
After the TCA Chemical Peel
Dr. Branman may prescribe a mild pain medication to relieve any tingling or throbbing you may feel. If tape was used to cover your face, it will be removed after a day or two. A crust or scab will form on the treated area. To help your face heal properly, it is essential that you follow our specific post-operative instructions. A TCA peel can cause some swelling, which will vary depending on the strength of the peel used.
