A TCA peel is a noninvasive skin treatment used to treat skin discolorations, scarring, and wrinkles. These peels get their name from trichloroacetic acid (TCA), which is used to clear away dead skin cells to reveal the newer and smoother skin layers below.
TCA peels are part of the group of skin treatments called chemical peels, which are used to exfoliate your skin by using different strengths and combinations of nontoxic acid ingredients.
