In this study, the antioxidant and anti-wrinkling effects of extracts from Aruncus diocius var. kamtschaticus (ADV) were investigated. According to the results, the ethanol extract has better antioxidant and anti-wrinkling effects than the water extract. The amounts of total polyphenol and flavonoid compounds in the ethanol extract were 122 and 36 mg/g, respectively, while those in the water extract were 87 and 26 mg/g. The antioxidant activities of the ethanol and water extracts were 395 and 4,682 ${mu}g/mL$ as the $RC_{50}$ values for the DPPH radical scavenging activity, and 227 and 366 ${mu}g/mL$ for the $ABTS^+$ radical scavenging activity, respectively. The reducing power of the ethanol extract (1.58 at 2 mg/mL) was higher than that of the water extract (0.88 at 2 mg/mL). The astringent activities of the ethanol and water extracts were 91.27 and 16.35% at 10 mg/mL, respectively. Furthermore, the ADV ethanol extract treatment of the fibroblast cell after UV irradiation resulted in increased cell viability (10% at 100 ${mu}g/mL$) and collagen biosynthesis (33% at 100 ${mu}g/mL$), with a lowering in the MMP-1 expression level (16.8 % at 100 ${mu}g/mL$). These results demonstrate that AVD provides a remarkable and significant tensor and anti-wrinkling effect on the skin, which could be of a great use in anti-aging skin care products.
