Effect of Collagen Peptides on Skin Health: A Clinical Trial
Effect of Collagen Peptides on Skin Health: A Clinical Trial
NCT ID: NCT07516756 Phase: NA Status: COMPLETED Enrollment: 66 Completion: 2024-10-04
Conditions
Age-related Changes in Skin Appearance and Physiology
Interventions
Placebo, Specific Collagen Peptides
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.
Primary Outcome
stratum corneum hydration (SCH)
