Impact of Oral Supplementation of Specific Bioactive Collagen Peptides on Human Skin Physiology: A Randomized, Double-Blind, Placebo-Controlled Trial
In Brief
A clinical study evaluating Placebo and Specific Collagen Peptides for Age-related Changes in Skin Appearance and Physiology. Completed, enrolled 66 participants across 1 site.
Detailed Summary
The goal of this clinical trial is to evaluate whether daily oral supplementation with 2.5 g of specific bioactive collagen peptides (SCP) can improve skin physiology in healthy adult women aged 35-55 years. The main questions it aims to answer are: Does SCP supplementation increase skin hydration and barrier function? Does SCP improve skin elasticity, firmness, and collagen content? Does SCP reduce the appearance of periorbital wrinkles and improve overall skin appearance? Researchers will compare SCP supplementation to a placebo (a look-alike substance containing no collagen peptides) to see if SCP supports skin structure and appearance over eight weeks. Participants will: Consume one sachet of SCP or placebo daily for eight weeks Attend three study visits at baseline, week 4, and week 8 for facial imaging, instrumental skin measurements, and expert assessments Have objective measures taken, including skin hydration, transepidermal water loss, elasticity, firmness, dermal collagen content, and 3D wrinkle morphology Complete subjective skin assessments rated by trained evaluators using a visual analogue scale Report any adverse events or intolerance reactions at each visit This study is designed to provide an integrated evaluation of multiple skin parameters, including barrier function, biomechanical properties, dermal matrix composition, and wrinkle characteristics, in a single trial. By combining objective and subjective measures, the study aims to generate robust and clinically interpretable evidence for the effects of oral collagen peptide supplementation on skin health.

Timeline
Interventions
Participants in this arm receive a matching placebo sachet once daily for 8 weeks. The placebo contains plant-derived maltodextrin and is identical in appearance, taste, and texture to the collagen peptide supplement. It is dissolved in warm water and consumed orally. Participants continue their usual lifestyle habits while taking the placebo.
Participants in this arm receive 2.5 g of specific bioactive collagen peptides (VERISOL®) once daily for 8 weeks. The powder is dissolved in warm water and consumed orally. The supplement contains defined collagen peptides derived from bovine type I collagen, which have been shown to support skin hydration, elasticity, firmness, dermal collagen content, and wrinkle reduction. Participants continue their usual lifestyle habits while taking the supplement.
