The Claim

Daily oral supplementation with 2.5 grams of low-molecular-weight collagen peptides (≤1000 Da) for six weeks reduces facial wrinkle volume by 46% and wrinkle area by 44% in healthy women aged 30–65 with moderate to severe crow’s feet wrinkles, as measured by objective biometric imaging.

In plain English

Taking 2.5 grams of low-molecular-weight collagen peptides daily for six weeks reduces facial wrinkle volume by 46% and wrinkle area by 44% in healthy women aged 30–65 with moderate to severe crow’s feet wrinkles, as measured by biometric imaging.

See the scientific wording

Daily oral supplementation with 2.5 grams of low-molecular-weight collagen peptides (≤1000 Da) for six weeks significantly reduces facial wrinkle volume by 46% and wrinkle area by 44% in healthy women aged 30–65 with moderate to severe crow’s feet wrinkles, as measured by objective biometric imaging, indicating a clinically relevant improvement in visible skin aging.

Why this might work

Small collagen fragments from the supplement pass through the gut wall into the blood, travel to the skin, and signal skin cells to make more collagen, elastin, and moisture-retaining molecules. This rebuilds the skin's structure, making wrinkles shallower and smaller.
