The TSA has a handy little rule to help you figure out what's okay to bring in your carry-on bag. It's called the 3-1-1 rule: liquids, gels, and aerosols must be in containers of 3.4 ounces or less, and they have to fit in a clear, quart-sized zip-top bag. That's like, a small bag of chips, right?
Now, you might be thinking, what about my favorite moisturizer? Can I bring it, or do I need to leave it behind? The good news is, you can bring it, as long as it's in a container that's 3.4 ounces or less. But, if you've got a giant bottle of the stuff, you might need to check it instead.
So, how do you measure 3.4 ounces, exactly? It's not like you've got a liquid measuring cup just lying around, right? Well, most travel-sized toiletries are already in 3.4 ounce containers, so you're good to go. And if you're not sure, you can always check the label.
