INCI: Gellan Gum

Minor player

In short: Gellan Gum delivers texture and viscosity control, suits most skin types, and the evidence behind it is limited.

What it actually is

Gellan Gum: A chain, not a molecule. Built to an average chain length rather than an exact one, so any batch holds a spread around that average instead of a single compound.
There is no single molecule to draw here, and that is the useful part. Which layer things act on

The Glow take

Nice to have, and nothing to overthink.

Gellan Gum plays a quiet supporting role, rounding out a formula rather than being the reason you buy it.

Gellan Gum, answered

Is Gellan Gum safe during pregnancy?

Yes. Gellan Gum is considered safe to use during pregnancy and breastfeeding. As with anything, if you are unsure it is worth a quick word with your doctor or midwife.

Who should avoid Gellan Gum?

No specific group is flagged to avoid Gellan Gum. It is well tolerated by most skin. Still, introduce anything new one product at a time.

What concentration of Gellan Gum actually works?

Its concentration is rarely printed on the label, so use the ingredient list as your clue: near the top third it is likely doing real work, near the bottom it is more of a sprinkle.

This, for every label you own

One ingredient is easy. A full label is where it gets confusing. The Ingredient Decoder reads any product and tells you the honest truth, ingredient by ingredient.
