Pearl powder is a preparation of crushed pearls used in China for skin care, and in traditional Chinese medicine as an anti-inflammatory and detoxification agent.
Pearl powder is a finely milled powder made from freshwater pearls, which contains a number of amino acids and several minerals. It can also be made from saltwater pearls. It is considered by its proponents to help improve the appearance of the skin. A typical dose is 1 gram of pearl powder taken by mouth, traditionally mixed into water or tea, twice weekly.
