Abstract:

Collagen is a fibrous protein and an important part of the organism. Due to its good biological properties in beauty, it has become one of the most promising functional raw materials in skin care products. Cold-water fish collagen has excellent moisturising properties, anti-aging activity, biocompatibility and safety, leading to its increasingly widespread application in beauty and skin care products. The article provides a detailed overview of the methods used to extract collagen from cold-water fish and summarizes the differences between collagen from cold-water fish and warm-water fish in terms of collagen structure, amino acid composition, thermal stability and other physicochemical properties. Cold-water fish collagen has a lower content of proline and hydroxyproline, but the serine content is significantly higher than that of the warm-water fish. Among the aquatic collagen, the thermal stability of cold-water fish collagen is poor. In addition, the article describes the factors that cause skin aging and the effects of skin aging, summarizes the mechanisms by which collagen and its derivatives delay and improve skin aging, and introduces the forms of application and product types of cold-water fish collagen in beauty and skin care products. By summarizing and analyzing the extraction methods, properties and applications of cold-water fish collagen, we aim to provide a theoretical basis for the study of collagen from cold-water fish sources and the development of raw materials for beauty and skin care products.

Key words: collagen, cold-water fish, properties, skin care products
