Collagen formula with Djulis for improvement of skin hydration, brightness, texture, crow’s feet, and collagen content: A double‐blind, randomized, placebo‐controlled trial

This clinical study demonstrates the synergistic effect of fish collagen and Djulis (the main components) for the substantial improvements in hydration, brightness, crow's feet, texture, wrinkles, pores, surface spots, and collagen content in skin. The collagen drink comprehensively improved skin parameters for most subjects after 4-week intake and manifested competitive efficiency in comparison with other similar studies. We convince that the collagen drink may delay skin aging process and improve skin aging parameters.
