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.
Claims24
A cosmetic/dermatological regime or regimen for treating the signs associated with dryness of keratin minerals, comprising administering to an individual in need of such treatment, a thus effective amount of at least one extract of a non-photosynthetic and non-fruiting filamentous bacterium cultured in a medium which comprises at least one non-sulfurous mineral and/or thermal water.
A cosmetic/dermatological regime or regimen for treating a skin disorder related to a deficiency in excretion and/or secretion of sebum and/or physiologically restoring a suitable state of hydration of the stratum corneum and/or treating hyposeborrheic dry skin and/or stimulating sebum production, comprising administering to an individual in need of such treatment, a thus effective amount of at least one extract of a non-photosynthetic and non-fruiting filamentous bacterium cultured in a medium which comprises at least one non-sulfurous mineral and/or thermal water.
A cosmetic/dermatological regime or regimen for preventing and/or reducing wrinkles associated with dryness of the skin, comprising administering to an individual in need of such treatment, a thus effective amount of at least one extract of a non-photosynthetic and non-fruiting filamentous bacterium cultured in a medium which comprises at least one non-sulfurous mineral and/or thermal water.
A cosmetic/dermatological regime or regimen for treating dry keratin fibers and/or improving the comfort of dry skin and/or dry scalp, comprising administering to an individual in need of such treatment, a thus effective amount of at least one extract of a non-photosynthetic and non-fruiting filamentous bacterium cultured in a medium which comprises at least one non-sulfurous mineral and/or thermal water.
A cosmetic/dermatological regime or regimen for treating atopic dermatitis, atopic xerosis, seborrheic dermatitis and hyperkeratosis, comprising administering to an individual in need of such treatment, a thus effective amount of at least one extract of a non-photosynthetic and non-fruiting filamentous bacterium cultured in a medium which comprises at least one non-sulfurous mineral and/or thermal water.
A cosmetic/dermatological regime or regimen for preventing and/or treating dry keratin materials, dry and/or delicate skin, and/or for treating hyposeborrheic dry skin, and/or for preventing and/or treating itching and/or tautness and/or for stimulating sebum production, and/or for the treatment and/or prevention of skin disorders and/or disorders of the pilosebaceous unit related to a deficiency in excretion and/or secretion of sebum, and/or for preventing and/or treating dry or brittle keratin fibers, and/or for preventing and/or reducing wrinkles associated with dryness of the skin, comprising administering to an individual in need of such treatment, a thus effective amount of at least one extract of a non-photosynthetic and non-fruiting filamentous bacterium cultured in a medium which comprises at least one non-sulfurous mineral and/or thermal water.
A cosmetic/dermatological composition useful for treating the signs associated with dryness of keratin materials, comprising at least one extract of a non-photosynthetic and non-fruiting filamentous bacterium cultured in a medium which comprises at least one mineral and/or thermal water and at least one other active agent selected from the group consisting of vitamins B3, B5, B6, B8 C, E or PP, carotenoids, curcuminoids and niacin.
A cosmetic/dermatological composition useful for treating the signs associated with dryness of keratin materials, comprising at least one extract of a non-photosynthetic and non-fruiting filamentous bacterium cultured in a medium which comprises at least one mineral and/or thermal water and at least one other active agent selected from the group consisting of desquamating agents;
- moisturizing agents;
- anti-glycation agents;
- anti-inflammatories or calmatives;
- agents for stimulating keratinocyte proliferation and/or differentiation;
- anti-dandruff agents;
- and anti-microbial agents.
