What it is

Hyaluronic acid is a humectant — it draws and holds water in the skin for a plumper, hydrated feel. It's a headline ingredient in serums and moisturisers and suits most skin types.

What the sources say

Hyaluronic acid is a permitted, well-tolerated cosmetic ingredient with no notable safety flag. Its only Clarra-relevant nuance is sourcing for the vegan axis.

Hazard vs. real-world risk

No hazard concern applies. The one honest ambiguity is vegan status: it's now usually made by fermentation (vegan), but was historically animal-derived, and the source isn't always declared on the label.

Vegan & cruelty-free angle

Now usually fermented and vegan, but the source isn't always stated on the INCI list — so vegan status can be genuinely ambiguous.

Calm by design

Most ingredient apps lean on fear-red warnings. Clarra is deliberately the opposite: a warm, editorial interface with plain-English bands like 'generally well tolerated' or 'flagged or restricted'. Fear makes for engagement but poor decisions. We'd rather you leave informed and calm than anxious and misled — which also means correcting myths about ingredients that sound worse than their sourced record.

What Clarra reads on every product

  • Ingredient flags — how named regulators (EU CosIng, IARC, Prop 65, CIR, ECHA) classify or restrict what's inside, with hazard kept separate from risk.
  • Cruelty-free status — shown with positive framing: what a brand states or is certified for, never an accusation.
  • Vegan status — flagging animal-derived ingredients like carmine, beeswax and lanolin, and honest about ambiguous-source ones.

Frequently asked

Is hyaluronic acid vegan?

Usually — modern hyaluronic acid is typically made by bacterial fermentation, which is vegan. Historically it could be animal-derived, and the label rarely says which. Where a brand confirms fermentation, Clarra can reflect that.

Where does Clarra get this information?

From open, public regulatory sources — the EU Cosmetic Ingredient database (CosIng) and Annexes, IARC, California Prop 65, CIR and ECHA — each cited on the ingredient. It's informational only, not medical or safety advice.
