Collagen is a family of fibrous proteins naturally present in animal connective tissues and, in consumer products, it is most commonly sourced from bovine, porcine, or marine raw materials. In supplements it is frequently used as hydrolysed collagen, also labelled as “collagen peptides”, where the protein is broken down into smaller peptides to improve solubility and ease of use in powders, capsules, tablets, and ready-to-mix drinks. On labels it may appear as “hydrolyzed collagen” or “collagen peptides”, with the origin sometimes specified as marine, bovine, or porcine. In cosmetics, collagen is typically declared under the INCI name “Hydrolyzed Collagen” and is used in water-based formulas such as serums, creams, and masks, often at modest concentrations alongside humectants and film-forming polymers. As a material, it is a mixture primarily composed of amino acids, peptides, and proteins, with properties influenced by the source and degree of hydrolysis. Because it is protein-based, collagen-containing products can have a characteristic taste or odour, so flavoured options are also common.
