Collagen pills promise younger skin – but do they deliver?
NCT ID NCT07516756
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether taking 2.5 grams of specific collagen peptides daily for 8 weeks can improve skin hydration, elasticity, and wrinkles in healthy women aged 35-55. Sixty-six women took either the collagen supplement or a placebo. Researchers measured skin moisture, barrier function, and wrinkle depth using specialized instruments and expert ratings. The goal is to see if a simple oral supplement can visibly support skin health.
