Collagen Extract
What is Collagen Extract?
Collagen extract comes from animal connective tissues, like bovine hides, porcine skin, or marine sources such as fish scales, where it's processed into soluble protein fragments rich in amino acids including glycine, proline, and hydroxyproline. Classified as a conditioning agent in skincare and haircare formulations, it typically appears in moisturizers, lotions, shampoos, and conditioners. Its primary function involves forming a lightweight film on the skin or hair cuticle, which locks in moisture as a humectant, minimizes water loss, and smooths rough textures by reducing surface friction. This molecularly large protein remains on the outer layers without deep penetration, supporting overall suppleness and ease of styling without altering underlying structures.
