Dihydromyricetin May Attenuate Skin Aging as a RAGE Inhibitor.

ABSTRACT: Background/Objectives: Dihydromyricetin (DHM), a flavonoid with abundant natural sources, potent bioactivity, and high safety, holds promise for translational applications, particularly in mitigating skin aging. However, its role and underlying mechanisms in counteracting skin aging induced by advanced glycation end products (AGEs) remain unclear. Methods: Eight-week-old male Sprague-Dawley (SD) rats were subcutaneously injected with 500 mg/kg D-galactose and administered DHM via gavage for 11 weeks. Additionally, senescent human skin fibroblasts (HFF-1) induced by AGEs were used for further investigation. Results: DHM treatment significantly alleviated D-galactose-induced skin aging in rats, with the most pronounced effects observed in the moderate-dose group (100 mg/
