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.

First claim

What is claimed is:

1. A cosmetic/dermatological method for reducing the bags and/or dark circles around the eyes of an individual afflicted therewith, the method comprising:
making a culture medium, which comprises adding (a) osmosed and/or distilled waters 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, at least 100 mg/l calcium ions, and at least 4 mg/l sulfates, wherein (b) is added in the range of 0.5 to 50 percent 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 culture of 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
topically administering to said individual an effective amount of said composition;
wherein said non-photosynthetic and non-fruiting filamentous bacterium is selected from the group consisting of Vitreoscilla filiformis, Vitreocilla beggiatoides, Beggiatoa alba, Flexithrix dorotheae, Leucothrix mucor , and Speaerotilus natans.

2. The cosmetic/dermatological method as defined by claim 1 , wherein the method reduces hyperpigmentation of the suborbital region and/or lightening dark circles afflicting said individual.

3. The cosmetic/dermatological method as defined by claim 1 , wherein the method renders the complexion of the region of the dark circles afflicting said individual uniform with the remainder of his or her face.

4. The cosmetic/dermatological method as defined by claim 1 , wherein said extract is comprised in a concealer eye contour cream, a concealer eye contour gel or a concealer stick.

5. The cosmetic/dermatological method as defined by claim 1 , said medium further comprising autolyzed yeast extract, plant peptone, anhydrous glucose, Heller microelements and calcium chloride.

6. The cosmetic/dermatological method as defined by claim 1 , said at least one extract comprising Se, Sr and Zn.

7. A cosmetic/dermatological method for treating the vascular component of a disorder of the eye contour of an individual afflicted therewith, the method comprising:
making a culture medium, which comprises adding (a) osmosed and/or distilled waters 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, at least 100 mg/l calcium ions, and at least 4 mg/l sulfates, wherein (b) is added in the range of 0.5 to 50 percent 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 culture of 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
topically administering to said individual an effective amount of said composition;
wherein said non-photosynthetic and non-fruiting filamentous bacterium is selected from the group consisting of Vitreoscilla filiformis, Vitreocilla beggiatoides, Beggiatoa alba, Flexithrix dorotheae, Leucothrix mucor , and Speaerotilus natans.
