Exfoliation has become a common practice in facials and other cosmetic treatments. The outer layers of skin contain a significant number of dead cells. Removal of these cells, called exfoliation, produces a cosmetically cleaner appearance. With the surge of interest in this practice, many cosmetic producers began using tiny pieces of materials in their products to enhance exfoliation. Some of these materials, such as pumice and salts, are natural products, but others are synthetic materials such as polymeric microbeads.
