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 aimed to evaluate the efficacy and safety of oral hydrolyzed collagen peptide (HCP) in healthy females by assessing the skin parameters via biophysical and skin imaging techniques. : 112 females were randomly assigned to receive either HCP ( = 57; 10 g CollaSel Pro ) or placebo ( = 55; 10 g maltodextrin) daily for eight weeks. The contribution of HCP to skin elasticity, hydration, and roughness was investigated against a placebo, while the facial soft tissue sagging (RMS) and safety data were also recorded. : HCP was associated with significant improvements in skin elasticity ( = 0.009), skin hydration ( ranged from 0.003 to
