The invention relates to the cosmetic use, as a skin moisturizer, of a compound of formula (I): with (i) R 1 and R 2 represent a hydrogen atom or a C 1 -C 6 -alkyl group, or (ii) R 1 and R 2 can form, together with the nitrogen atom which bears them, a saturated heterocycle with 5 to 7 ring members; R 5 representing a hydrogen atom or a (C 1 -C 3 ) alkyl group; R 6 representing a hydrogen atom or a (C 1 -C 4 ) alkyl group; R 3 represents a hydrogen atom or a (C 1 -C 6 ) alkyl-group, or —OR 3 represents a phosphate group; it being possible for the two groups R 3 to form, together, an isopropylidene group; R 4 represents a hydrogen atom or —OR 4 represents a-phosphate group; and the salts, solvates and isomers thereof. The invention also relates to a cosmetic composition comprising a compound (I) and the corresponding new compounds. |
