A TCA peel is a medium depth peel for lighter skin types which uses trichloroacetic acid to exfoliate skin.
Stronger than superficial peels, TCA (trichloroacetic acid) peels are effective in treating pigmentation issues, wrinkles, and sun damage. They require longer downtime and may cause temporary redness and peeling. TCA peels are also not made for darker skin types.
This is classified as a medium peel.
