What is Soluble Collagen?

Soluble collagen consists of low-molecular-weight peptides obtained by hydrolyzing collagen, the main structural protein in animal connective tissues such as bovine hides, fish skins, or porcine sources. This process renders it water-soluble, ideal for incorporation into cosmetic formulations like creams, lotions, serums, shampoos, and conditioners. Primarily functioning as a humectant, it binds moisture to the skin's outer layer and hair shafts, promoting hydration and suppleness. As a film former, it deposits a sheer coating that enhances smoothness, reduces friction, and provides a barrier against moisture loss. Its protein structure also neutralizes static charges on hair, aiding manageability, while contributing to a softening effect on both skin and strands through surface conditioning.
