Collagen Amino Acids

What is Collagen Amino Acids?

Collagen amino acids consist of small peptides and free amino acids derived from the hydrolysis of collagen protein, typically sourced from animal origins such as bovine hides or fish scales. This process breaks down the large collagen molecule into bioavailable components rich in glycine, proline, and hydroxyproline. In cosmetics, they belong to the category of conditioning agents and humectants. They function by drawing moisture into the skin and hair shafts, forming a lightweight film that enhances texture and reduces friction. This mechanism supports surface-level hydration without penetrating deeply into living skin layers, making them suitable for leave-on products like creams, serums, and shampoos where they contribute to a smoother, more supple feel.
