Abstract: The present invention provides an agent containing an orotic acid derivative that has high solubility in solvent and has superior physiological activity. The agent of the present invention is a melanin production inhibitor, whitening agent, fibroblast activator, collagen and/or elastin production promoter or wrinkle ameliorant containing as an active ingredient thereof an orotic acid derivative represented by the following general formula (1) or a salt thereof. In formula (1), R preferably represents a side chain of glutamic acid, glycine, histidine or aspartic acid. [In formula (1), R represents a side chain of a naturally-occurring amino acid and R may form, together with a nitrogen atom adjacent thereto through a single carbon atom, a hetero ring].
