Fig. 1. Effect of myricetin on UVB-induced wrinkle formation in SKH-1 hairless mice.
(A) The chemical structure of myricetin (3,3′,4′,5,5′,7-hexahydroxyflavone). (B) Representative image showing the anti-photoaging effects of myricetin. Mice were topically treated with 200 μl of acetone containing 0, 1, or 5 nmol myricetin (as described in “Materials and methods”) and then irradiated with UVB light 3 times/wk for 15 wks. Images of the mouse backs were recorded using a digital camera (Samsung, Korea) before the mice were euthanized at the end of the experiment. Images shown are representative of those from 5 or 6 mice.
