Skin appearance through gene manipulation

1. A method of ameliorating or reducing the manifestation or the appearance or depth of lines, wrinkles or creases around the mouth and eyes, between the eyes and on the forehead resulting from chronological aging, hormonal aging, photo-aging and/or actinic aging wherein the method comprises effecting at least a 2 fold up regulation in the expression of one or more genes associated with improving or maintaining the health and integrity of the dermal-epidermal junction (DEJ), at least a 2 fold down regulation in the expression of one or more genes associated with the degradation of the DEJ, or both by administering orally to an individual or topically or intradermally to the aforementioned areas of the skin of an individual manifesting lines, wrinkles or creases a gene manipulatingly effective amount of a composition having a pH of 3.5 to 7 and comprising from 0.5 to 10 wt. percent of a meroterpene and a dermatologically or pharmaceutically acceptable carrier on at least a daily basis until the aforementioned amelioration or reduction is visually noted to the satisfaction of the user, wherein said meroterpene is of the formula

wherein R 1 , R 2 , and R 3 are each independently selected from the group consisting of H, OH, OR 6 or CH 2 R 6 where R 6 is a linear or branched C 1 to C 8 alkyl; and R 4 and R 8 are each independently a linear or branched, C 1 to C 20 alkyl or alkenyl group, said meroterpene having a purity of at least 60%.

2. The method of claim 1 wherein gene manipulatingly effective amount is sufficient to induce at least a four-fold up-regulation or down-regulation of at least one gene associated with the health or degradation, respectively, of the DEJ.

3. The method of claim 1 wherein the up-regulation or down-regulation, as appropriate, occurs in at least one of the following genes: LAMA3, LAMC2, ITGA6, ITGB2, ITGB4, ITGB6, ITGB8, COL4A6, COL17A1, AND HS3ST1.

4. The method of claim 1 wherein the composition is administered orally at a rate sufficient to provide a dosing of from about 10 mg to about 500 mg per day, once or twice a day.

5. The method of claim 1 wherein the composition is administered intradermally to the afflicted areas of the skin at a rate sufficient to provide a dosing of 0.1 mg/cm 2 to 10 mg/cm 2 .

6. The method of claim 1 where the composition is administered topically to the afflicted areas of the skin at a rate sufficient to provide a dosing of 0.1 mg/cm 2 to 10 mg/cm 2 .

7. The method of claim 1 where the composition is administered topically to the afflicted areas of the skin at a rate sufficient to provide a dosing of 1 mg/cm 2 to 2 mg/cm 2 .

8. The method of claim 1 wherein the meroterpene is present in the composition in an amount of from 1 to 5 weight percent.

9. The method of claim 1 wherein the meroterpene is selected from bakuchiol, hydroxy bakuchiol, and corylifolin.

10. The method of claim 9 wherein the meroterpene is substantially free of coumarins.

11. The method of claim 1 wherein the meroterpene is selected from bakuchiol, hydroxy bakuchiol, and corylifolin and has a purity of at least 95%.

12. The method of claim 9 wherein the meroterpene is substantially free of coumarins.

13. The method of claim 1 wherein the meroterpene is bakuchiol.

14. The method of claim 9 wherein the meroterpene is bakuchiol.

15. The method of claim 9 wherein the meroterpene is bakuchiol.

16. The method of claim 1 wherein the composition is applied as a topical composition and further includes at least one of a moisturizer, a skin softener, a cosmetic, a skin care active, and a sunscreen.
