Please Explain the Healing Process from 10% TCA Peel

A 10% TCA Peel, in and of itself, does very little to the skin. There may be a small amount of superficial flaking. There is essentially no downtime and there should be virtually no restrictions following a 10% TCA application. I feel very strongly and it has been my experience over the past 22 years that glycolic acid applications in appropriate strengths (50% glycolic acid peel and 10% glycolic acid home applications) are far superior in achieving improved facial skin complexion. Accordingly, TCA is not currently in my treatment armamentarium.

The strength of the peel depend on the acid used, the PH, and how many layers you apply.
Your color is probably safe for peels but I would still prep your skin for the peel.
Also, remember that you are in Africa and the sun is too intense and that may cause pigmentation problems.
USE SUNSCREEN, about SPF 45. TCA 10% will NOT improve wrinkles.

The lower the Percentage of TCA, the weaker the acid. It is neutralized by water, ie weakened.
Your complexion is "wheat" colored. I would be very careful because you can get hyperpigmentation after the peel.
10 % TCA will not improve wrinkles it will improve texture slightly so consider the risk benefit of doing by yourself. If you choose to do it, start with the small amount very light with barely any on your gauze and see how it goes. And than wash it off with cool water.
Be careful.
