Collagen: What The Science Really Says
Collagen peptides are one of the rare beauty supplements with randomised controlled trials behind them — with realistic, measurable rather than magical results.

What the trials show
Meta-analyses of hydrolysed collagen report improvements in skin hydration and elasticity after 8–12 weeks at 2.5–10 g per day.
Nail strength and hair thickness improve more modestly, and only with consistent use.
Make it work harder
Vitamin C is required for collagen synthesis, so take the two together. Sun protection matters more than any supplement.
Key takeaways
- 2.5–10 g hydrolysed peptides daily
- Allow 8–12 weeks before judging results
- Pair with vitamin C and daily SPF
