Abstract

The present invention relates to the cosmetic use of a lysate of a bacterium or bacteria belonging to the Vitreoscilla sp. genus (in particular of the Vitreoscilla filiformis species) in a complete fermentation medium, as an active agent for preventing and/or treating hyperseborrhoeic conditions not associated with a dandruff condition of the scalp.

First claim

1 . A cosmetic and/or dermatological composition for preventing and/or treating hyperseborrhoeic conditions of the scalp of an individual, not associated with a dandruff condition of the scalp, said composition comprising, in a physiologically acceptable medium, at least one lysate of a bacterium or bacteria belonging to the Vitreoscilla sp. genus in a complete fermentation medium.

2 . The composition according to claim 1 , wherein said composition is in the form of a hair lotion, a shampoo, or a hair conditioner.

3 . A method for preventing and/or treating hyperseborrhoeic conditions of the scalp of an individual, not associated with a dandruff condition of the scalp, comprising at least one step of administering to said individual at least one lysate of a bacterium or bacteria belonging to the Vitreoscilla sp. genus in a complete fermentation medium.

4 . The method according to claim 3 , wherein said bacterium is a Vitreoscilla filiformis strain.

5 . The method according to claim 3 , wherein said process is carried out topically.

6 . The method according to claim 3 , wherein the complete fermentation medium is all or part, in terms of amount, of the fermentation medium which has been used for the fermentation of said bacterium and in which its cell lysis was consecutively carried out.

7 . The method according to claim 3 , wherein the lysate and complete fermentation medium mixture contains the cytoplasmic fractions, the cell wall fragments, and the metabolites formed and/or released during the cell lysis of said bacterium and the water-soluble metabolites generated and released spontaneously by the bacterium during its fermentation process.

8 . The method according to claim 3 , wherein said bacterium is the Vitreoscilla filiformis (ATCC 15551) strain.

9 . The composition according to claim 1 , wherein said bacterium is Vitreoscilla filiformis or Vitreoscilla beggiatoe.
