Carbohydrates are one of the main dietary components, including sugars, starches, and fibers. Carbohydrates are classified as simple or complex. The classification depends on the chemical structure of the food, and how quickly the sugar is digested and absorbed. Simple carbohydrates have one (single) or two (double) sugars. Complex carbohydrates have three or more sugars. Carbohydrates have excellent performance in moisture maintenance and damping. The excellence is more obvious used in cleansing facial milk and all kinds of creams. Adding a certain amount of Carbohydrates to cosmetics not only can prevent the moisture content in cosmetics from disappearing, but also make hydration to the moisture on the cuticle. Cosmetics with Carbohydrates are also easy to be absorbed by the skin.
