The 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 is like a fair test where half the women took a special powder and half took sugar powder — and only the powder group saw their skin get smoother and tighter. That means the powder probably caused the improvement, not just luck.
