Effects of a Ready-to-Drink Hydrolyzed Collagen from Sea Bass Skin on Skin Health: A 30-Day Clinical Trial

Year: 2025

Type: article

Abstract: Food waste from fish processing contributes significantly to environmental pollution, and fish skin is often discarded despite being a rich collagen source. This study evaluated the efficacy and consumer satisfaction of a ready-to-drink collagen supplement made from hydrolyzed collagen derived from seabass skin. The compositional analysis of this study revealed α-amino groups, hydroxyproline, and amino acids essential for skin elasticity, hydration, and tissue repair. A 30-day clinical trial was conducted in 36 Thai volunteers who were aged between 20 to 70 years, and their skin condition was assessed using a facial skin analyzer and a moisture analyzer on days 0, 15, and 30. Participants also completed self-perception and sensory satisfaction questionnaires. The results showed improved skin moisture, reduced pore size, and smoother skin texture. Participants reported high satisfaction, especially regarding increased moisture and skin smoothness. Sensory score evaluation showed favorable scores for color and taste; however, odor was the least preferred attribute with the lowest score. Notably, no adverse effects were reported throughout this study. The findings suggest that fish skin-derived collagen supplements can enhance skin appearance while offering a sustainable approach that converts fish by-products into functional skincare solutions aligned with global sustainability goals.
