Trichloroacetic Acid Peel (TCA Peel)

Stronger than glycolic acid, trichloroacetic acid helps smooth the surface of the skin, refine pores and reduce fine lines through the stimulation of reproductive collagen. This peel process is a deep skin exfoliation that also helps to reduce acne.

With a TCA peel, healed skin will be able to produce pigment as always and it 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.

Anesthesia is not required for TCA peels because the chemical solution acts as an anesthetic. However, sedation may be used before and during the procedure to help the patient relax.

The surgeon will carefully apply the TCA solution to thoroughly cleansed skin. There is a stinging sensation as the peel solution is applied but this feeling will quickly pass.

A full-face TCA peel usually takes about 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. Protecting skin from the sun is important following a TCA peel. Your doctor will recommend a sun block with adequate UVA and UVB protection to be used everyday.
