See the scientific wording

Oral collagen peptide supplements significantly improve skin hydration and elasticity in humans.

Why this might work

When collagen peptides are swallowed, they survive digestion and enter the bloodstream. These peptides travel to the skin and signal skin cells to make more collagen, elastin, and hyaluronic acid. The extra collagen and elastin strengthen the skin's structure, while hyaluronic acid holds water, making the skin more hydrated and elastic.
