An amine derivative of following general formula (I) or (II) (wherein R¹ represents a heteroatom-containing nC₁-C₄₀ hydrocarbon group which may have a ring structure, etc.; R² to R⁶ each represent a C₁-C₁₀ hydrocarbon group, nhydrogen, etc.; A¹ represents (i) or R¹⁵-Z-R¹⁶(CH₂) n -; B¹ represents hydrogen, a C₁-C₁₀ hydrocarbon group, nitrogen, netc.; and C¹ represents hydrogen, a C₁-C₁₀ hydrocarbon group, nitrogen, alcohol residue, phosphoric acid residue, netc.); a dermatologic preparation containing the same; and a process for producing the amine derivative. The amine nderivative has excellent effects of smoothing wrinkles and improving keratodermia. |
