A randomized, triple‐blind, placebo‐controlled, parallel study to evaluate the efficacy of a freshwater marine collagen on skin wrinkles and elasticity
Journal of Cosmetic Dermatology Aug 20, 2020
Evans M, Lewis ED, Zakaria N, et al. - Researchers conducted this randomized, triple‐blind, placebo‐controlled study to test the effectiveness and safety of a hydrolyzed marine collagen (Vinh Wellness Collagen, VWC) on aspects of skin health and quality in women between 45‐60 years of age. Using the VISIA skin analysis system, Cutometer and Skin Quality Visual Analogue Scale, assessments of skin wrinkles, elasticity and self‐reported appearance were conducted. At weeks 0 (baseline), 6 and 12, outcomes were assessed. Participants supplemented with VWC had a significant 35% decline in wrinkle score from baseline after 12 weeks. Participants in the VWC group showed a 24% decrease in wrinkles on the right side of the face compared with placebo. At week 12, VWC group participants reported higher percentage improvements in overall skin score and wrinkle, elasticity, hydration, radiance and firmness scores vs placebo. Overall, the authors concluded that supplementation with VWC has been found to be well‐tolerated and safe. The use of fish‐derived hydrolyzed collagen for the improvement of skin health in an aging population was supported in this analysis.
