How Long Does It Take for Skin to Finish Peeling After a TCA Peel?

TCA
Peels take about a week to peel and another week or so to heal. How
much visible peeling there is depends on the individual, your skin
type, and the strength of the peel. You are probably peeling
microscopically. If you don't see results within two weeks, check
back with your physician. Best, Dr. Emer

Thank you for your question.
It takes about a week for a TCA peel to finish peeling, and then another week for the skin to regenerate. For stronger peels, the healing process my take slightly longer, and of course, the vice versa is true with weaker peels.
For weaker peels, it is often common to not see the actual peeling of the skin, but know that there is a peeling effect nonetheless, just on a more microscopic scale. Still, the treatment must be the same - gentle cleansing and application of a healing ointment or cream (Aquaphor, Bionect, Biafine, etc.) for 1-2 weeks.
Hope this helps!
