The Effects and Mechanisms of Collagen Peptides for Alleviating Skin Aging

This review highlights the potential benefits of collagen peptides in delaying skin aging, particularly through enhancing skin elasticity, hydration, and reducing wrinkles. Numerous clinical trials have supported these effects, although results vary due to differences in study design and participant characteristics. Oral collagen peptide supplementation is generally well-tolerated, with no serious adverse events reported. The review also explores the potential of topical applications, noting challenges in transdermal delivery. Despite promising findings, further research is needed to understand the mechanisms and optimize formulations for effective use in skin health.
