A TCA peel is a medium depth peel for lighter skin types which uses trichloroacetic acid to exfoliate skin.
TCA (trichloroacetic acid) peels work more deeply than superficial peels, making them highly effective for treating pigmentation, wrinkles, and sun damage. As a result, they deliver more noticeable improvements.
However, they also require longer downtime and often cause temporary redness and peeling. Due to these risks, providers generally avoid using TCA peels on darker skin types, as they may lead to scarring or uneven pigmentation. Overall, this peel falls under the category of a medium-depth peel.
