摘要

Pharmaceutical and/or cosmetic compositions designed for application to the human or animal skin, comprising a pseudoceramide of general formula (I), wherein RSUP1/SUP is an alkyl with the chain length of from CSUB12/SUB to CSUB20/SUB; RSUP2/SUP is an alkyl or alkenyl with the chain length of from CSUB15/SUB to CSUB29/SUB, the minimal number of carbons in the molecule being 36, in amounts of from 0.01 to 20 weight %, based on the total weight of the composition, in a pharmaceutically acceptable vehicle. The compositions are designed for relipidization of the skin as well as for supplementary treatment of skin diseases associated with lowered lipid content and increased skin permeability. They can be used for treatment of damaged, dry or ageing skin and skin adnexa or for prevention of skin damage and skin adnexa. Novel pseudoceramides of general formula (II) are also described.
