Collagen
What is Collagen?
Collagen is a fibrous protein that naturally forms triple-helix structures, making up a key part of skin's extracellular matrix, tendons, and bones. In cosmetic formulations, it comes mainly from animal origins like cow hides, pig skin, or fish byproducts, frequently hydrolyzed into soluble peptides to enhance stability and spreadability. Classified as a skin and hair conditioning agent, it functions superficially by creating a breathable film on the surface, which binds water molecules to boost hydration levels and improve tactile qualities. This ingredient appears in lotions, creams, masks, shampoos, and serums, where it aids in maintaining suppleness and reducing surface friction without absorbing deeply due to its large molecular size.
