Aging is a natural process that will cause physiological changes in organs. The effects of djulis and green caviar in skincare are currently unclear. This study combined hydrolyzed collagen with djulis and green caviar to develop new functional formulas that improve skin parameters. Fifty subjects were randomly assigned and divided into a placebo group (n=25) and a collagen drink group (n=25), and gave 50 ml of collagen of a collagen drink or placebo drink daily for 28 days, and we examined skin moisture, elasticity, gloss, spot, wrinkle, roughness, smoothness, pore, collagen and erythema. We find that intake of collagen drinks group improved skin parameters at 14 days and 28 days compared with baseline (0 day). The collagen drinks group improved skin parameters at 28 days compared with the placebo group. This clinical study proved the combination of collagen with djulis and green caviar for the substantial improvements in moisture, elasticity, gloss, spot, wrinkle, roughness, smoothness, pore, collagen, and erythema in the skin.
