Skincare · counts as serum

Short answer

Both Ordinary Niacinamide sizes are under 100ml, so they're fine in your cabin bag.

Rule basis: Sizes sold: 30ml, 60ml.

What to do: Cabin: containers ≤ 100ml. Checked: any size.

Liquid Limits is a travel planning tool, not an official aviation source. Always confirm with the airport before you travel.

In cabin baggage

The Ordinary Niacinamide counts as a liquid/gel under the standard airport rules. That means containers up to 100ml (3.4 fl oz) in your cabin bag, all fitting inside a single 1-litre clear plastic bag. A few airports with CT scanners (Gatwick, Edinburgh, Bristol, Amsterdam, parts of JFK) allow up to 2 litres, but never plan around that for both ends of your trip.

In checked luggage

The Ordinary Niacinamide travels fine in checked luggage at any size. Wrap it in a sealed plastic bag — pressure changes at altitude can pop seals, and an exploded tub costs you everything around it.

Real-world examples

FAQs

Does The Ordinary Niacinamide count as a liquid?

Yes — security treats anything pourable, spreadable or pasty as a liquid, including creams, balms in jars, and serums.

What's the smartest way to travel with The Ordinary Niacinamide?

Decant a few days' worth into a 30ml or 50ml refillable jar from Muji, Sephora or Boots. You keep your full-size pot at home and your liquids bag stays light.

Will an unopened The Ordinary Niacinamide get confiscated if it's over 100ml?

Yes. Security goes by the container size printed on the bottle, not whether it's sealed. New, unopened, half-full — none of that matters.
