Abstract:	Crassocephalum rabens (Asteraceae) is a common herb used in Taiwanese folk medicine to treat inflammation-related syndromes. Pharmacological studies have revealed that galactolipids exhibit anti-oxidative, anti-inflammatory, and anti-hyaluronidase activities and improve skin wrinkles, moisture, and elasticity in healthy subjects. However, the anti-aging effects of C. rabens and its primary active compound, 1,2-di-O-linolenoyl-3-O-beta-galactopyranosyl-sn-glycerol (dLGG), remain elusive. Here, we investigated whether C. rabens can improve skin conditions in healthy individuals using a double-blind approach. Forty enrolled volunteers were randomly and equally assigned to the control or treatment group and were required to take either a placebo or a C. rabens extract capsule daily for one month. Skin parameters were measured before and after the study. The results showed significant differences in skin elasticity, wrinkles, collagen content, brightness, and hydration between the baseline and week 4 in the treatment group. Particularly, compared with those in the placebo group, skin wrinkles (p < 0.05), brightness (p < 0.001), collagen content (p < 0.01), and UV spots (p < 0.05) were notably improved after treatment with the C. rabens extract. Our study successfully demonstrated the application of C. rabens in preventing skin aging. Further investigations will be conducted to study the underlying anti-aging mechanism of dLGG.
