What the research found

Oral collagen peptides (2.5–10 g/day) consistently increase skin elasticity, hydration, and dermal density while decreasing wrinkle volume across multiple randomized controlled trials. In mild-to-moderate atopic dermatitis, a trial of 5 g daily of bioactive collagen peptides over 12 weeks significantly reduced topical corticosteroid rescue medication requirements.
