Findings
Women who took 2.5g of specific collagen peptides daily for 8 weeks saw a 20% reduction in eye wrinkles compared to placebo, with results lasting even 4 weeks after stopping. The peptides also boosted skin's production of collagen (up 65%) and elastin (up 18%), the proteins that keep skin firm and bouncy.
