Abstract: The present invention relates to novel C-glycoside compounds of given absolute configuration, to a process for synthesizing them and to compositions containing them. The invention also relates to the cosmetic use of these C-glycoside compounds as agents to stimulate the synthesis of glycosaminoglycans containing a D-glucosamine and/or N-acetyl-D-glucosamine residue, advantageously hyaluronic acid, and/or of proteoglycans, advantageously proteoglycans containing hyaluronic acid, by fibroblasts and/or keratinocytes. The invention also relates to a cosmetic process for treating keratin materials using a composition containing at least one C-glycoside compound according to the invention.

Abstract: Hair growth-/hair loss-affecting cosmetic/therapeutic compositions contain an effective amount of at least one 2-amino-4-alkylaminopyrimidine 3-oxide having the structural formula (I): in which R1 is an alkyl radical having from 5 to 20 carbon atoms, and Z is either a hydrogen atom or a radical −OR2, wherein R2 is an alkyl radical having from 1 to 12 carbon atoms, or an acyl derivative or acid addition salt thereof.

Abstract: The invention relates to the use, as active principle, in a physiologically acceptable medium, in a composition, of an effective amount of at least one compound of the indolecarboxylic family, this compound or these compositions being intended to treat disorders associated with overactivity of 5&agr;-reductase. These compounds or the compositions containing them are more particularly intended to treat androgen-dependent disorders such as, for example, seborrhoea and/or acne and/or hirsutism and/or androgenic alopecia. The invention also relates to novel compounds of the indolecarboxylic family and to compositions-containing them.

Abstract: Hair growth-/hair loss-affecting cosmetic/therapeutic compositions contain an effective amount of at least one 2-amino-4-alkylaminopyrimidine 3-oxide having the structural formula (I): 1
