Topical application of milk brings out the natural beauty of skin. Milk contains lactic acid, an alpha hydroxy acid (AHA) that exfoliates the skin, removing dead cells from the skin’s surface and promoting the generation of fresh skin cells. Regular application of milk to the skin encourages the skin’s natural regeneration process. AHAs in milk also help to reduce the depth of the fine lines and wrinkles caused by skin aging. AHAs slough off the dead skin cells that cling to the skin’s surface and stimulate collagen production, which diminishes the appearance of lines and wrinkles.
