Benefits of technology

[0016]In another aspect, the present invention is directed to methods of treating skin in need of improving skin barrier function with a topical composition comprising extracts of Ampelopsis grossedentata and Albizia julibrissin.
[0017]In yet another aspect, the present invention is directed to methods of treating skin inflammation by applying to a skin in need of reducing skin inflammation a topical composition comprising extracts of Ampelopsis grossedentata and Albizia julibrissin.
[0018]In yet another aspect, the present invention is directed to methods of treating skin aging by applying to a skin in need of improving signs of aging a topical composition comprising extracts of Ampelopsis grossedentata and Albizia julibrissin.

Problems solved by technology

Dry skin can cause many skin problems including atopic dermatitis, eczema, psoriasis and pruritus.
This ultimately results in the pathology of skin inflammation.
This decline can be caused by skin barrier dysfunction.
Dry skin, aging, itching and other skin problems are related to decreased differential ability and metabolism of skin.

Preparation of Ampelopsis grossedentata Extract from Leaves (E1)

[0160]Ampelopsis grossedentata plants were collected in China. Species identification was based on gross morphological characteristics [Flora of China Editorial Committee. Flora Reipublicae Popularis Sinicae. Beijing: Science Press, 1998, 48: 53.]. Plants were cleaned of soil and debris and separated into aerial parts and roots. Approximately 1000 g of leaves were homogenized in a blender with 5000 mL of 95% ethanol / water; the suspension was maintained in constant motion for 24 hours. The resulting suspension was then filtered and dried under low pressure using a rotary evaporator not exceeding 40° C. After filtration, the left over raw material was again extracted as described above. The combined dry mass from both extractions was designated the crude extract, approximately 270 g, for a yield of 27.0% (E1).

Preparation of Albizia julibrissin Extract from Flowers (E2)

[0162]Albizia julibrissin plants were collected in China. Species identification was based on gross morphological characteristics [Flora of China Editorial Committee. Flora Reipublicae Popularis Sinicae. Beijing: Science Press, 1998, 39: 65]. Plants were cleaned of soil and debris and separated into aerial parts and roots. Approximately 2000 g of flowers were homogenized in a blender with 12,000 mL of 95% ethanol / water; the suspension was maintained in constant motion for 24 hours. The resulting suspension was then filtered and dried under low pressure using a rotary evaporator not exceeding 40° C. After filtration, the left over raw material was again extracted as described above. The combined dry mass from both extractions was designated the crude extract, approximately 144 g, for a yield of 7.2% (E2).

Determination of Filaggrin Protein Promotion

[0164]Extracts E1, E2 and combinations of the two at 1:1 (0.001% E1+0.001% E2) were tested for filaggrin protein levels using the method of Assay 1 described above. The crude extract was diluted with DMSO (dimethyl sulfoxide) as a 10% solution. Then the diluted extract was added to the cell culture media. Additional DMSO was added so that the concentration of the extract in the cell culture media was 0.001% by weight and the amount of DMSO was 0.1% in the cell culture media. The blank control was the 0.1% DMSO solvent by weight in the cell culture media.

[0165]The results are given in Table 1 below.
