You are allowed to bring a quart-sized bag of liquids, aerosols, gels, creams and pastes through the checkpoint. These are limited to 3.4 ounces (100 milliliters) or less per item. This is also known as the 3-1-1 liquids rule.

In 2026, the answer depends on the specific technology at the airport you are using. Under the standard TSA 3-1-1 rule, you can carry a 100g (or 100ml) container of cream in your hand luggage, provided it is placed inside a single, quart-sized, clear plastic bag. However, "cream" is legally considered a "Liquid, Aerosol, or Gel" (LAG); even if it is thick like peanut butter or heavy face cream, it must follow the size restriction. The "pro" tip for 2026 is that many major hubs (like London Heathrow, Amsterdam Schiphol, and select terminals at JFK) have installed new CT scanners. At these specific "Next-Gen" checkpoints, you may be allowed to keep your liquids—including larger containers of cream—inside your bag without taking them out or following the 100ml limit. But beware: unless you are 100% sure the return airport also has this technology, you should stick to the 100g/100ml limit to avoid having your expensive skin cream confiscated on the way home. Always check if the container is 100ml capacity; a 200ml jar that is "half full" will still be rejected by traditional security.
