The Claim
Oral polypeptide supplements reduce wrinkle severity in adults with signs of aging, with a mean difference of 1.5 units on standardized wrinkle scales (p=0.01) based on subgroup analysis.
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.
Oral polypeptide supplements decrease wrinkle severity in aging adults by an average of 1.5 points on standardized wrinkle scales. This reduction was observed in a subgroup analysis of a study.
See the scientific wording
Oral polypeptide supplements modestly reduce wrinkle severity in adults with signs of aging, with a mean difference of 1.5 units on standardized wrinkle scales (p=0.01) in subgroup analysis.
Oral polypeptide supplements are broken down in the stomach and absorbed into the blood. These small peptides travel to the skin, where they attach to skin cells called fibroblasts. This attachment triggers signals inside the fibroblasts that tell them to produce more collagen, elastin, and hyaluronic acid. These proteins rebuild the skin's support structure, making wrinkles less visible.
What the research says
1 studyYes, the research found that taking collagen peptides by mouth can slightly reduce wrinkles, especially the larger polypeptide type, which matches what the claim says.
