TCA Peel (Trichloroacetic Acid Peel)

Trichloroacetic acid (TCA) can be used in many concentrations, but it is most commonly used for medium-depth peeling. Fine surface wrinkles, superficial blemishes and pigment problems are commonly treated with TCA. The results of TCA peel are usually less dramatic than and not as long-lasting as those of a phenol peel. In fact, more than one TCA peel may be needed to achieve the desired result. The recovery from a TCA peel is usually shorter than with a phenol peel.

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.

Trichloroacetic Acid (TCA)

Uses:
  • Smooths out fine surface wrinkles
  • Removes superficial blemishes
  • Corrects pigment problems
Considerations:
  • Can be used on neck or other body areas
  • May require pre-treatment with Retin-A or AHA creams
  • Treatment takes only 10-15 minutes
  • Preferred for darker-skinned patients
  • Peel depth can be adjusted
  • Repeat treatment may be needed to maintain results
  • Sunblock must be used for several months
  • Healing is usually quick, much quicker than with a phenol peel
TCA Peels: Typically, the skin is first thoroughly cleansed. Then, the surgeon will carefully apply the phenol or TCA solution. 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 a TCA peel, your doctor 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 your doctor's specific post-operative instructions.

A TCA peel may also cause significant swelling, depending on the strength of the peel used.

With a TCA peel, the moderate discomfort and mild swelling you may experience will subside within the first week. In about a week to ten days, your new skin will be apparent and you should be healed sufficiently to return to your normal activities. It is best to avoid sun exposure unless you are adequately protected.
