The Glow take

The kind of ingredient sensitive skin quietly loves.

Allantoin earns its place by calming things down: less redness, less sting, a happier barrier. Not a headline active.

Allantoin, answered

Is Allantoin safe during pregnancy?

Yes. Allantoin 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 Allantoin?

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

What concentration of Allantoin 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
