Claims33
A cosmetic treatment method applied to combat ageing of skin comprising a step of applying, to the skin or to the scalp, a composition comprising a biomass obtained from a culture of at least one bacterium selected from the group consisting of Pseudomonas vesicularis and Pseudomonas maltophilia,
- wherein said biomass is obtained by culturing said at least one in a culture medium bacterium and separating the biomass from the culture medium and optionally at least partially dehydrating, sterilizing, purifying, grinding and/or acylating the separated biomass.
A cosmetic treatment method applied to improve appearance and tonicity of dry skin comprising a step of applying, to the skin or to the scalp, a composition comprising a biomass obtained from a culture of at least one bacterium selected from the group consisting of Pseudomonas vesicularis and Pseudomonas maltophilia,
- wherein said biomass is obtained by culturing said at least one in a culture medium bacterium and separating the biomass from the culture medium and optionally at least partially dehydrating, sterilizing, purifying, grinding and/or acylating the separated biomass.
A cosmetic treatment method applied to preserve or improve skin elasticity comprising a step of applying, to the skin or to the scalp, a composition comprising a biomass obtained from a culture of at least one bacterium selected from the group consisting of Pseudomonas vesicularis and Pseudomonas maltophilia,
- wherein said biomass is obtained by culturing said at least one in a culture medium bacterium and separating the biomass from the culture medium and optionally at least partially dehydrating, sterilizing, purifying, grinding and/or acylating the separated biomass.
A cosmetic treatment method applied to improve appearance of skin which exhibits a local inflammatory reaction comprising a step of applying, to the skin or to the scalp, a composition comprising a biomass obtained from a culture of at least one bacterium selected from the group consisting of Pseudomonas vesicularis and Pseudomonas maltophilia,
- wherein said biomass is obtained by culturing said at least one in a culture medium bacterium and separating the biomass from the culture medium and optionally at least partially dehydrating, sterilizing, purifying, grinding and/or acylating the separated biomass.
A cosmetic composition comprising, as an active ingredient, a biomass obtained from a culture of at least one bacterium selected from the group consisting of Pseudomonas vesicularis and Pseudomonas maltophilia, in combination with an excipient that is acceptable in cosmetology,
- wherein said biomass is obtained by culturing said at least one in a culture medium bacterium and separating the biomass from the culture medium and optionally at least partially dehydrating, sterilizing, purifying, grinding and/or acylating the separated biomass.
