The Claim
Oral supplementation with hydrolysed collagen and vitamin C for 12 weeks results in a 13.8% increase in skin hydration compared to placebo in adults aged 40-60 years, as measured by corneometry.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Taking hydrolysed collagen and vitamin C supplements daily for 12 weeks increases skin hydration by 13.8% compared to a placebo in adults aged 40 to 60 years. This increase was measured using a device called a corneometer.

When you take collagen supplements, your body breaks them down into small pieces that travel through your blood to your skin. These pieces tell skin cells to make more collagen. Vitamin C in the supplement helps the new collagen get built correctly and protects it from damage. The extra collagen helps your skin hold onto more water, making it feel more hydrated.
What the research says
1 studyThe study tested the exact same supplement and duration as the claim, and found that skin hydration improved by exactly 13.8%, just like the claim says.
