Efficacy and Safety of Skin Radiance Collagen on Skin and Hair Matrix: A Placebo-Controlled Clinical Trial in Healthy Human Subjects

The placebo-controlled clinical study involved 37 healthy adult females aged 38–50 years and evaluated the effects of Skin Radiance Collagen (SRC), a supplement containing marine collagen, vitamin C and E, hyaluronic acid, and biotin. The study found that SRC significantly reduced hair fall by 28% and improved skin elasticity after 56 days of treatment. Additionally, skin hydration improved by 15.69% and crow’s feet wrinkles decreased by 48.11% in the SRC group. The Physician Global Assessment score for skin appearance also improved by 29.35% in the SRC group. 68% of subjects had a change in Glogau skin type from type III to type II. All participants reported satisfaction with SRC, stating it improved skin moisturization, texture, radiance, and hair health. The study concluded that SRC is effective in reducing hair fall, improving skin elasticity, hydration, roughness, and wrinkles, and rejuvenating skin.
