Is TCA okay to use on different skin colors?
Yes, TCA does not penetrate into the pigment layer of the skin, so it will not permanently change skin color as does a stronger peel such as Phenol. Although the new skin after a TCA peel may appear somewhat lighter, it will normalize back to its usual color in a matter of weeks. This is due to the new skin having never been exposed to the sun. The surrounding skin appears darker since it is tanned.
