What is it ?
Trichloroacetic acid (TCA) is a chemical peel agent used to treat changes in the papillary dermis. It is primarily used in preparing medium peels and can be present in lower concentrations in superficial peels. A TCA peel involves 4 to 7 days desquamation.
TCA coagulates epidermal proteins, causing frosting on the skin (whitish colour) upon application. It accelerates cellular renewal in the dermis and specifically stimulates collagen production by inducing collagenation.
For anyone wishing to treat their pigmentary imperfections.
