Bacterial extracts cultured in thermal waters for treating sensitive skin, mucous membranes and scalps

摘要

Sensitive skin, mucous membranes and scalps are treated by administering to individuals in need of such treatment, 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.

主权项

1. A cosmetic/dermatological method for treating skin, mucous membranes, the scalp or a combination thereof, the method comprising:
making a culture medium; which comprises adding (a) osmosed and/or distilled water and (b) a second water comprising a total concentration of carbonates or bicarbonates of at least 150 mg/l, at least 6 mg/l of silicon oxide, greater than or equal to 100 mg/l of calcium ions and at least 4 mg/l of sulfates; wherein (b) is added in a range of 0.5 to 50% based on the amount of osmosed and/or distilled water of (a); culturing a non-photosynthetic and non-fruiting filamentous bacterium in said medium to produce a culture5 sad non-photosynthetic bacterium in said medium; preparing a composition comprising between 0.001% and 20% by weight of an extract of said cultured bacterium; and administering said composition to skin, mucous membranes, scalp or a combination thereof of an individual; wherein said non-photosynthetic and non-fruiting filamentous bacterium is selected from the group consisting of Vitreoscilla filiformis, Vitreoscilla beggiatoides, Beggiatoa alba, Flexithrix dorotheae, Leucothrix mucor and Sphaerotilus natans.
