In personal care

A protein extract, usually derived from animal connective tissue (commonly bovine, porcine, or marine sources), processed and purified for use in skincare formulas.

Why it’s used

Used as a conditioning and film-forming ingredient on the skin's surface. It can help the skin feel smoother and temporarily plumper, and it holds some water, giving it mild humectant properties.

What the evidence says

We haven’t found a source for this one that you can open and check, so we’re not summarizing the evidence.

Look it up yourself

We would rather point you at the shelf than summarize something you can’t check. These are the same places we search:

  • PubChem — what the substance is, chemically — names, synonyms and structure
  • PubMed — every paper indexed by the US National Library of Medicine that names it

These are starting points, not our findings — we haven’t run them for you. A substance whose name is also an ordinary word (“Heart”, “Alanine”, “Water”) will return papers that are not about the ingredient at all.
