Claim:
A wrinkle-reducing agent, comprising a compound represented by the following general formula (1), a stereoisomer of the compound or a pharmacologically acceptable salt thereof: where: R 1 represents a hydrogen atom or a linear or branched alkyl group having 1 to 8 carbon atoms; R 2 represents —SO 3 H, —SO 2 —X 4 , —SO 2 —NY 1 —X 5 , or —SO 2 —NY 2 —Y 3 , provided that the X 1 to X 5 each independently represent an aliphatic hydrocarbon group having 1 to 8 carbon atoms or an aromatic moiety having 5 to 12 carbon atoms, in which a heteroatom may be substituted for a hydrogen atom or a carbon atom, and the Y 1 to Y 3 each independently represent a hydrogen atom or a linear or branched alkyl group having 1 to 8 carbon atoms; R 3 represents a hydrogen atom or an acyl group having a linear or branched alkyl chain having 1 to 8 carbon atoms; R 4 represents a phenyl group, a toluoyl group, an ethylphenyl group, a propylphenyl group, a butylphenyl group, a pentylphenyl group, a hexylphenyl group, a methoxyphenyl group, an ethoxyphenyl group, a propyloxyphenyl group, a butyloxyphenyl group, a pentyloxyphenyl group, a hexyloxyphenyl group, a naphthyl group, a methylnaphthyl group, a methoxynaphthyl group, a biphenyl group, a pyridyl group, or a quinolyl group; m represents an integer of 0 to 3; and n represents an integer of 1 or 2.
