What is a TCA Peel? TCA stands for Trichloroacetic Acid . It is derived from acetic acid (or the vinegar family). TCA is non-toxic solution that has been used as an ingredient in skin peeling for many years. TCA face peel is usually stronger than other peels because it penetrates deeper into the skin, and hence offers more advanced benefits for the skin.
