Compositions comprising
View Patent ↗Provided are compositions comprising an extract of Paulownia tomentosa wood and methods of use thereof.
1. A method of lightening human skin comprising topically applying to human skin in need of skin lightening an effective amount of a composition comprising from greater than zero to about 20% of a polar extract of Paulownia tomentosa wood, wherein said polar extract is obtained by extraction of Paulownia tomentosa wood with one or more solvents selected from the group consisting of: ethanol, methanol, or a combination thereof.
2. The method of claim 1 , wherein said composition comprises from about 0.2% to about 2% of the polar extract of Paulownia tomentosa wood.
3. The method of claim 1 , wherein said composition comprises from about 0.01% to about 5% of the polar extract of Paulownia tomentosa wood.
4. The method of claim 1 , wherein said composition further comprises a carrier, and wherein said composition is in the form of: a solution, suspension, lotion, cream, serum, gel, stick, spray, ointment, liquid wash, soap bar, shampoo, hair conditioner, paste, foam, powder, mousse, shaving cream, hydrogel, or film-forming product.
5. The method of claim 4 , wherein said composition is transferred from a substrate to the skin.
6. The method of claim 5 , wherein said substrate is a wipe or facial mask.
7. The method of claim 1 , wherein said composition further comprises an additional skin lightening active agent.
8. The method of claim 7 , wherein said composition is transferred from a substrate to the skin.
9. The method of claim 8 , wherein said substrate is a wipe or facial mask.
10. The method of claim 1 , wherein said composition comprising the polar extract of Paulownia tomentosa wood is applied once or twice daily for at least 2 weeks.
11. The method of claim 1 , wherein said composition comprising the polar extract of Paulownia tomentosa wood is in the form of two or more different compositions.
12. The method of claim 11 , wherein said two or more different compositions comprising the polar extract of Paulownia tomentosa wood are are selected from the group consisting of: lotions, cleansers, masks, essences, wipes, creams, serums, gels, and combinations thereof.
13. The method of claim 12 , wherein one of said two or more different compositions is in the form of a cleanser and another of said two or more different compositions is in the form of a lotion or cream.
14. The method of claim 12 , wherein said two or more different compositions comprising the polar extract of Paulownia tomentosa wood are at least three different compositions, and wherein said at least three compositions are selected from the group consisting of: cleansers, lotions, creams, essences, facial masks and combinations thereof.
15. The method of claim 1 , wherein said human skin in need of skin lightening treatment is selected from the group consisting of: skin darkened by UV, skin with uneven skin tone, skin having one or more pigmented spots, melanin spots, age spots, sun spots, senile lentigos, freckles, lentigos simplex, pigmented solar keratosis, seborrhoeic keratosis, melasma, acne marks, and combinations of two or more thereof.
16. The method of claim 15 , wherein said human skin in need of skin lightening treatment is selected from the group consisting of: skin having one or more pigmented spots, melanin spots, age spots, sun spots, freckles, acne marks, and combinations of two or more thereof.
17. The method of claim 1 , wherein said polar extract of Paulownia tomentosa wood is essentially free from extracts of non-wood parts of Paulownia tomentosa.
18. The method of claim 17 , wherein said polar extract of Paulownia tomentosa wood is essentially free from extracts of leaves and bark of Paulownia tomentosa.
19. The method of claim 1 , wherein said polar extract of Paulownia tomentosa wood is essentially free of ursolic acid, beta-sitosterol, or both.
20. A method of lightening human skin comprising topically applying to human skin in need of skin lightening an effective amount of a composition comprising from about 0.2% to about 2% of a polar extract of Paulownia tomentosa wood, wherein said polar extract is essentially free of ursolic acid, beta-sitosterol, or both, and wherein said polar extract of Paulownia tomentosa wood is obtained by extraction with ethanol, methanol, or a combination thereof.
21. The method of claim 20 , wherein said polar extract of Paulownia tomentosa wood is essentially free from extracts of non-wood parts of Paulownia tomentosa.
22. The method of claim 21 , wherein said polar extract of Paulownia tomentosa wood is essentially free from extracts of bark and leaves of Paulownia tomentosa.
