An amine derivative of following general formula (I) or (II) (wherein R<1> represents a heteroatom-containing C1-C40 hydrocarbon group which may have a ring structure, etc.; R<2> to R<6> each represent a C1-C10 hydrocarbon group, hydrogen, etc.; A<1> represents (i) or R<1><5>-Z-R<1><6>(CH2)n-; B<1> represents hydrogen, a C1-C10 hydrocarbon group, nitrogen, etc.; and C<1> represents hydrogen, a C1-C10 hydrocarbon group, nitrogen, alcohol residue, phosphoric acid residue, etc.); a dermatologic preparation containing the same; and a process for producing the amine derivative. The amine derivative has excellent effects of smoothing wrinkles and improving keratodermia. <CHEM>
