A natural mineral used for sun protection like a physical barrier between your skin and the sun. Used in sunscreens and cosmetic products.
Trichloroacetic Acid (TCA)*
A key ingredient in chemical peels used to treat sun damage and hyperpigmentation, TCA promotes shedding of the outermost layer of dead skin cells, allowing new cells to rise to the surface in the days following treatment. TCA peels are generally light to medium strength, with the former requiring a series of two to three for best results; the latter requiring only a single session (but carrying about a week of downtime).
