While the primary goal of a Brightening Facial is to enhance overall skin brightness, it also addresses another common concern—discoloration. The skin contains melanin, the pigment responsible for determining its color. In healthy skin, melanin is evenly distributed. However, when skin cells are damaged or function abnormally, they can begin to overproduce melanin, resulting in clusters of excess melanin in certain areas. These patches appear darker and discolored.
