The Claim

Among women taking 2.5 grams of low-molecular-weight collagen peptides daily for six weeks, 90% report high satisfaction with improvements in skin hydration and wrinkle appearance, and these subjective assessments align with objective biometric measurements.

In plain English

In a six-week study, 90% of women who took 2.5 grams of low-molecular-weight collagen peptides daily reported high satisfaction with improved skin hydration and reduced wrinkles, and these reports matched objective measurements of skin changes.

See the scientific wording

Subjective assessments by participants align with objective measurements, showing that 90% of women taking 2.5 grams of low-molecular-weight collagen peptides daily for six weeks report high satisfaction with improvements in skin hydration and wrinkle appearance, reinforcing the clinical relevance of the observed biometric changes.

Why this might work

After being swallowed, small collagen pieces pass through the gut wall into the blood and travel to the skin. There, they trigger skin cells to make more collagen, elastin, and a moisture-retaining substance called hyaluronic acid. This rebuilds the skin's structure, making it hold more water and smoothing out wrinkles.
