Abstract: Red blotches on the skin such as those associated with environmental stresses, or red blotches associated with a skin disorder, for example those occurring during rosacea, are treated/reduced by administering to individuals afflicted therewith, thus effective amounts of at least one extract of a non-photosynthetic and non-fruiting filamentous bacterium cultured in a medium which includes at least one non-sulfurous mineral and/or thermal water, e.g., an extract derived from the bacterium Vitreoscilla filiformis, in particular the strain ATCC 15551, cultured in a medium enriched with water from La Roche Posay.

Abstract: Bags and/or dark circles around the eyes of individuals afflicted therewith are reduced by administering to such individuals thus effective amounts of at least one extract of a non-photosynthetic and non-fruiting filamentous bacterium cultured in a medium which includes at least one non-sulfurous mineral and/or thermal water, e.g., an extract derived from the bacterium Vitreoscilla filiformis, in particular the strain ATCC 15551, cultured in a medium enriched with water from La Roche Posay.

Abstract: Dryness of keratin materials, in particular dryness of the skin, and especially disorders associated with dry and/or hyposeborrheic skin are treated by administering to individuals afflicted therewith, thus effective amounts of at least one extract of a non-photosynthetic and non-fruiting filamentous bacterium cultured in a medium which includes at least one non-sulfurous mineral and/or thermal water, e.g., an extract derived from the bacterium Vitreoscilla filiformis, in particular the strain ATCC 15551, cultured in a medium enriched with water from La Roche Posay.

Abstract: Composition containing a conditioned cell culture medium or an extract thereof, said medium being able to be obtained by contact with at least one culture of digestive tract cells and at least one probiotic microorganism. It also relates to the use of conditioned culture medium for improving skin homeostasis, etc.

Abstract: The invention relates to compositions containing an agent that has an irritant side effect and a conditioned cell culture medium and/or of an extract thereof, for use, e.g., in the treatment of signs of inflammation and/or of immune disorders, the medium being obtainable by contact with at least one culture of digestive tract cells and at least one probiotic microorganisms. Methods of use.

Abstract: The present invention relates to the use of an effective amount of at least one microorganism belonging to the species Lactobacillus paracasei or casei, a fraction thereof or a metabolite thereof, in combination with an effective amount of at least one microorganism belonging to the species Bifidobacterium longum or Bifidobacterium lactis, a fraction thereof or a metabolite thereof, for producing a dermatological composition intended for treating and/or preventing reactive sensitive skin that may or may not be associated with dryness of the skin.

Abstract: An orally administrable composition for the photoprotection of the skin which comprises a photoprotecting effective amount of i) at least one probiotic lactic acid bacterium or a culture supernatant thereof, and ii) at least one yeast, included into an orally acceptable carrier.
