The Claim
Peptide supplementation does not significantly improve skin elasticity or density in adults, as demonstrated by meta-analyses showing non-significant pooled mean differences for elasticity (MD=0.09, p=0.15) and density (MD=2.33, p=0.22).
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.
Peptide supplements do not improve skin elasticity or density in adults. Multiple studies combined show no meaningful difference compared to placebo.

When people take peptide supplements, the peptides travel through the blood to the skin. There, they signal skin cells to make more collagen and elastin. Other peptides help enzymes link these fibers together, and some peptides block enzymes that break down collagen. However, when measured in studies, these changes are not large enough to make a noticeable difference in skin firmness or thickness.
What the research says
1 studyThis study checked if taking peptide supplements makes skin firmer or thicker, and it found no significant improvement, just like the claim says.
