<P>PROBLEM TO BE SOLVED: To obtain an active oxygen scavenging agent causing excellent moisture retention to the skin, chapped skin-improving, and having aging-preventing and bleaching effects on the skin by scavenging active oxygen, inhibiting the production of lipoperoxides in the skin, promoting hyaluronic acid producing ability of a skin cell and inhibiting the decomposition ability and further promoting aquaporin synthesis of a skin cell, and to obtain an inhibitor for synthesis promotion/decomposition of hyaluronic acid and an aquaporin synthesis promotor. <P>SOLUTION: The active oxygen scavenging agent, the inhibitor for synthesis promotor and decomposition of the hyaluronic acid and the aquaporin synthesis promotor comprise each an extract obtained from a plant of the family Tropaeolaceae. <P>COPYRIGHT: (C)2004,JPO |
