Abstract

The invention concerns a cosmetic composition for treating or preventing disorders associated with a greasy skin, in particular by an activity reducing sebum secretion, comprising as active principle at least one dicarboxylic fatty acid or one derivative of such a fatty acid. The invention concerns in particular cosmetic compositions for topical administration. The invention also concerns a cosmetic method for treating or preventing disorders associated with hyperseborrhea.

Claims

1. A cosmetic composition for the care of oily skin, characterized in that it contains at least one fatty dicarboxylic acid or one of its active derivatives, in a concentration of less than 0.5 mM, preferably in the range 1 nM to 0.1 mM, more preferably in the range 0.01 μ

M to 10 μ

M.

2. A cosmetic composition according to claim 1, in which the fatty dicarboxylic acid is selected from fatty alcohol esters, sugar esters and amides.

3. A cosmetic composition according to claim 1, characterized in that the fatty dicarboxylic acid or the fatty dicarboxylic acid portion of the derivative is linear and contains 8, 9 or 10 carbon atoms.

4. A cosmetic composition according to claim 1, comprising a plurality of fatty dicarboxylic acid derivatives in which the fatty dicarboxylic acid portion is linear and contains 8, 9 or 10 carbon atoms.

5. A cosmetic composition according to claim 1, containing azelaic acid in a concentration in the range 0.1 μ

M to 10 μ

M.

6. A cosmetic composition according to claim 1, in which each fatty dicarboxylic acid or fatty dicarboxylic acid derivative is a pure molecule, a plant extract or a microorganism extract.
