In personal care

An extract taken from the leaves of the aloe vera plant, typically the gel-like inner portion. It can appear as a liquid, powder, or thicker concentrate depending on how it's processed.

Why it’s used

It's included mainly for its humectant and soothing reputation, drawing in moisture and giving a calming feel to lotions, gels, and after-sun products. It's as much a marketing signal as a functional ingredient in many formulas.

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.
