Marine Collagen is a liquid hydrolysed collagen ingredient derived from deep-water fish and used in cosmetic formulations for skin and hair care. It is water soluble and works best in the water phase or cool-down phase of suitable formulas, making it especially useful in serums, lotions, shampoos, and conditioners. This is a cosmetic ingredient, not a ready-to-use serum or supplement. Its liquid format makes it easy to blend into water-based formulations where a moisture-supporting marine protein is wanted.
♡ Why we love it: Marine collagen is one of those quietly effective formulation ingredients that adds a lovely touch to both hair and skin care. It is easy to use, blends well into water-based products, and helps make everyday formulas feel more polished and conditioning.
