Does Hydrolyzed Collagen Skin Meta-Analysis work?

The current Migaku evidence database contains 2 reusable source documents for Hydrolyzed Collagen Skin Meta-Analysis. This answer focuses on strength of evidence and what the studies can or cannot prove. - Introduction Skin aging manifests as wrinkles, reduced elasticity, and roughness due to intrinsic and extrinsic factors. [Nukaly HY (2026); evidence level 1] - Peptides, particularly oral formulations, significantly improved hydration and brightness, with a modest pooled effect on wrinkle reduction (MD = 0.27, p = 0.04). [Nukaly HY (2026); evidence level 1] - Peptide-based therapies enhance collagen synthesis and extracellular matrix integrity. [Nukaly HY (2026); evidence level 1] - Results Supplementation with 10 g/day of BCP significantly reduced the number (p Conclusions A 12-week course of Peptpure ® BCP supplementation improved facial skin health, underlined by increased systemic levels of TGF-β and Klotho, suggesting activation of regenerative and antiaging pathways. [Paula-Vieira RHR (2026); evidence level 4] - Introduction Collagen peptides are widely used to support skin health, but the immunological mechanisms mediating such effects remain unclear. [Paula-Vieira RHR (2026); evidence level 4] Evidence levels are sorting aids, not final clinical grades. Level 1 usually indicates systematic-review style evidence, level 2 indicates randomized trials or public-health guidance, and lower levels need more cautious wording. This page is educational.
