Abstract
Provided is a brightening use of a composition including sodium pyruvate and one or more selected from the group consisting of urea and hydroxyethyl urea. Since the composition exhibits a synergistic brightening effect, even when a low concentration of sodium pyruvate is included, a brightening effect at the same level as when a high concentration of sodium pyruvate is used can be obtained. Therefore, the composition can be effectively applied in cosmetics, medicines, external preparations, and the like.
