Cause and effect

In plain English

Taking 10 grams per day of CollaSel Pro® hydrolyzed collagen peptide results in measurable improvements in skin elasticity, hydration, and roughness in healthy adult females, even when no other nutrients or bioactive compounds are included.

See the scientific wording

The skin-improving effects of 10g/day CollaSel Pro® hydrolyzed collagen peptide are observed without added vitamins, minerals, or other bioactive compounds, suggesting that hydrolyzed collagen alone can improve skin elasticity, hydration, and roughness in healthy adult females.

Why this might work

After swallowing collagen peptides, they enter the bloodstream and reach the skin, where they trigger skin cells to make more of the natural proteins that keep skin firm, stretchy, and moist. This rebuilds the skin's structure, making it smoother, more hydrated, and less saggy.

  1. Study: The Efficacy and Safety of CollaSel Pro® Hydrolyzed Collagen Peptide Supplementation without Addons in Improving Skin Health in Adult Females: A Double Blind, Randomized, Placebo-Controlled Clinical Study Using Biophysical and Skin Imaging Techniques

    This study gave women a daily collagen powder with nothing else in it, and after two months, their skin became more elastic, more hydrated, and smoother—proving the collagen itself worked, not any extra vitamins or ingredients.
