Every aesthetic treatment happens on or in the skin. If you do not understand the skin you are treating, you cannot treat it safely. This prerequisite course covers skin architecture, melanocyte biology, clinical conditions specific to African patients — from keloids to dermatosis papulosa nigra to traction alopecia — and a cosmeceutical module covering retinoids, niacinamide, tranexamic acid, and the newest emerging agents. The foundation every subsequent course stands on.
