Does Collagen Skin Elasticity Meta-Analysis work?

The current Migaku evidence database contains 3 reusable source documents for Collagen Skin Elasticity 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] - Skin hydration/elasticity improved sustainably for 3 months, with only 1.67% adverse events and no serious ones. [Yang Rongya (2026); evidence level 2] - This large-scale randomized controlled trial complements the existing evidence base for the novel sodium hyaluronate composite, strongly supporting its safty and clinical efficacy in facial rejuvenation through mesotherapy. [Yang Rongya (2026); evidence level 2] 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.
