Marine Collagen
What is Marine Collagen?
Marine collagen is a protein sourced from the skin, scales, and bones of marine animals, mainly fish from sustainable fisheries. It undergoes hydrolysis to create smaller peptides rich in amino acids such as glycine, proline, and hydroxyproline, making it highly soluble in water. In cosmetic formulations, it serves as a skin conditioning agent, humectant, and film-former, appearing in creams, serums, masks, and moisturizers. It works by attracting and binding moisture to the skin's surface, while forming a breathable film that minimizes water loss and enhances skin suppleness. This marine-origin ingredient offers better bioavailability than land-based collagens due to its lower molecular weight, aiding immediate hydration and a smoother feel without deep penetration, as supported by cosmetic science evaluations.
