The present invention provides the substance of the moisture-keeping functions for participating in improving skin, new promotion silk polyprotein gene expression.It was found that silk polyprotein gene expresses increase and decrease with the rhythmicity of about 24 hours periods, after adding candidate substances, become maximum time screening of candidate substances in expression, pepper extract, 3- (1 '-piperidines)-propionic acid, pelargonium oil, cedar wood oil, attar of rose, kahikatea sesame oil, papper oil, basil, o-methyl benzoic acid methyl ester, methyl anthranilate, methyl methylanthranilate are determined as a polyprotein gene expression accelerating agent. |
