The Claim
Daily supplementation with 5g hydrolyzed collagen and 80mg vitamin C for 16 weeks reduces skin roughness (arithmetical mean roughness, Ra) by 9.6% in women aged 40-65, as measured by 3D topography.
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.
A daily supplement containing 5 grams hydrolyzed collagen and 80 milligrams vitamin C taken for 16 weeks reduces skin roughness by 9.6% in women aged 40 to 65, measured with 3D imaging.

Collagen and vitamin C from the supplement travel in the blood to the skin. Vitamin C helps skin cells make new collagen, while collagen peptides signal those cells to produce more collagen and stop breaking it down. This strengthens the skin's structure and smooths its surface.
What the research says
1 studyThe study used the exact same supplement and found that women's skin got about 10% smoother after 4 months, just like the claim says.
