TCA is a non-toxic chemical (trichloracetic acid) that is applied to the skin causing the top layers of cells to dry up and peel off over a period of several days to one week. When the old skin is peeled off, it exposes a new layer of undamaged skin, which has improved texture and tone.
TCA peels are commonly used to:
- reduce brown spots and age spots
- improve the texture of sun damaged skin
- improve melasma
- treat some types of acne
- reduce fine lines
