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.

C-glycosides, uses thereof

The present invention relates to novel C-glycoside compounds of given absolute configuration, to a process for synthesising 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.

Pyrimidine 3-oxide compounds for inducing/stimulating hair growth and/or retarding hair loss

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.

Compounds of the indolecarboxylic family and use thereof

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 &agr;-reductase. These compounds or the compositions containing them are more particularly intended to treat androgen-dependent disorders such as 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.

Indolecarboxylic compounds and their use as pharmaceutical compounds

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):

The invention relates to a novel derivative of kojic acid of formula (I) and to its use, in a composition for topical application as a depigmenting and/or bleaching agent for skin: ##STR1## The invention also relates to a process for depigmenting and/or bleaching skin, which includes applying to the skin a composition that contains 5-hydroxy-4-oxo-4H-pyran-2-ylmethyl 2-oxothiazolidine-4-carboxylate of formula (I) or a pharmaceutically acceptable salt thereof.
