Effect of Reducing Pigmentation by Collagen Peptide Intake: A Randomized, Double-Blind, Placebo-Controlled Study.

ABSTRACT:

Introduction

We examined the effect of 5.0 g/day of collagen peptide (CP) or collagen peptide fermented with Aspergillus sojae (FCP) on skin pigmentation in healthy participants.

Methods

In this randomized, double-blind, placebo-controlled study, 44 men and women aged 25-63 years were placed into three groups by stratified random allocation and treated with CP, FCP, or placebo (PL) at 5.0 g/day for 3 months. Their skin condition was measured monthly from baseline to 3 months of intake.

Results

No adverse events were identified in any group. The CP group showed a significant reduction in pigmented patches and redness after 1 and 3 months of intake, respectively. In the FCP group, pigmented macules were significantly reduced after 1 month, and pigmented patches after 2
