PARAKERATOSIS INHIBITOR AND EXTERNAL COMPOSITION FOR SKIN

摘要

[PROBLEMS] To provide a parakeratosis inhibitor, pore reducing agent and skin roughness preventive/ameliorating agent that exhibit capabilities of parakeratosis inhibition, pore reduction, skin roughness prevention/amelioration, etc., and further provide an external composition for skin having these capabilities. [MEANS FOR SOLVING PROBLEMS] There are provided a parakeratosis inhibitor and a pore reducing agent each comprising at least one compound selected from the group consisting of a glycine derivative, an aminodicarboxylic acid derivative, an acylaminodicarboxylic acid derivative, a pyrrolidinecarboxylic acid derivative, a piperidinecarboxylic acid derivative, a hexamethyleneiminecarboxylic acid derivative, a beta-alanine derivative and salts of these derivatives. Further, there are provided a parakeratosis inhibitor, a pore reducing agent and a skin roughness preventive/ameliorating agent each comprising at least one compound selected from the group consisting of specified glycine derivatives and salts thereof and specified aminosulfuric acid derivatives and salts thereof. Still further, there are provided external compositions for skin comprising these compounds.
