Can I bring niacinamide serum on a plane? - skincare bottle with woman's hands in it.

Yes, you can bring niacinamide serum on a plane. Niacinamide serum or products that have niacinamide in them as an ingredient are considered a liquid by TSA. Follow TSA’s guidelines for liquids and don’t bring more than 3.4 ounces or 100 ml of it with you in your carry-on. 

If you do need to bring more in your carry-on, keep reading. We have a solution for that.

How to pack niacinamide serum in your carry-on

No matter how much you want to bring with you, it’s best to pack your niacinamide serum in individual 3.4 ounce or 100 ml or smaller containers. Then place those with your other toiletries, including your other skincare products in a quart-sized ziploc bag to make screening quick and easy.

TIP – I always pack my toiletries and other liquids in these gallon-sized ziplocks and TSA hasn’t ever said anything about it. Including times they have looked through it by hand.

When you go through airport security, you may need to remove your liquids for a separate screening. That’s one of the reasons it is helpful to have them all in a clear bag. It makes it easy to grab and easy for the TSA agents to see what you have so you don’t have to unpack everything. 

Tips for packing liquids, glass bottles or fragile containers

  • Make sure your bottle is completely closed.
  • Put each bottle inside a separate zip-lock bag. 
  • If it’s going in checked bags, avoid placing it near the edges of the bag. Place it towards the middle and surround it with clothes or other soft items.
  • If it’s going in your carry-on or handbag, pack it with your other toiletries in the transparent, quart-sized zip-lock bag. Again, surround it with soft items and keep it packed in the middle of your hand luggage.

How many 3.4 oz containers can you bring on a plane?

You can bring between six and eight 3.4 ounce individual containers of liquids, aerosols or gels on a plane, so long as they fit in a 1-quart clear zip bag. Six to eight containers are approximately how many you can fit into one clear quart-size bag

These are the gallon-sized ziplocks I use instead of the quart-sized ones.

Can I bring niacinamide serum in checked baggage?

Yes, you can bring your niacinamide serum in unlimited quantities in checked baggage. Just make sure to pack it securely.

Keep in mind that each airline has weight restrictions for luggage. Liquids are quite heavy, so the weight of your luggage can add up quickly.

How to pack niacinamide serum in checked baggage

When packing niacinamide serum in checked baggage, make sure it’s closed tightly and secured to prevent spills in transit. Place it inside a plastic bag for extra protection against leaks. 

Consider placing it towards the center of your bag with clothes or other items packed securely around it to prevent it from breaking if and when your checked luggage gets dropped or thrown around.

Weigh your luggage before going to the airport as well to ensure it’s within the weight limit of your specific airline or you may have additional fees to pay when you go to check-in.

How much niacinamide serum can you take on a plane in checked baggage?

You can take as much niacinamide serum in your checked luggage as you would like, within reason. There is no limit set by the TSA on the quantity you bring in your checked bags. So long as you can pack it safely, you can bring it.

But you should double-check with your airline on the weight restrictions of your checked bags and don’t exceed those restrictions.

TIP – As you pack, consider creating more space in your bags by shipping it to your destination, buying it there, or ordering some online and shipping it to your final destination.

Here are some great options you could order online and ship to wherever you are traveling.

Can I use niacinamide serum every day when traveling?

It can be used up to two times daily as you travel depending on how your skin responds to it. If you experience significant stinging, redness or your skin breaks out consider reducing your usage. 

But you should be fine.

In addition, niacinamide can help build your skin cells by protecting them from UV radiation, pollution, and toxins. This is especially important if you spend a lot of time in the sun.

TIP – Acne with inflamed papules or pustules may benefit from niacinamide. Your acne may benefit from increased sun exposure on your trip and the serum.

What does niacinamide serum do for the skin?

Eczema, acne, and other inflammatory skin conditions may be eased by the anti-inflammatory properties of niacinamide. It also helps the skin regulate oil production, keeps skin smooth and moisturized, and may help reduce pore size over time. 

What is the TSA’s 3-1-1 rule for liquids?

The 3-1-1 liquids rule is a rule implemented by the Transportation Security Administration (TSA) that regulates how much liquid you can bring on a plane. It states you can bring up to 3.4 ounces or 100 ml of liquid on a plane. All of your liquids must be in separate containers of 3.4 ounces or less. And they must fit in one clear quart-size bag. 3.4 ounces, 100 ml, one quart-size bag. Hence, 3-1-1.

The 3-1-1 liquids rule can be misleading because not all the items that follow this rule are technically liquids. It also applies to gels, aerosols, creams, and anything in between. Here’s what @AskTSA has to say about the rule.

You won’t be able to bring more liquid than whatever will fit in the one quart-size bag.

TSA Liquid Rule Exceptions

For some liquids, the TSA makes exceptions to the 3-1-1 rule. You can bring more than 100 ml of the following liquids. 

  • Baby formula
  • Breast milk
  • Juice or water for babies
  • Medically necessary liquids, prescription liquids, and gels

To make screening smooth, let the TSA agent know how much of these liquids you have with you. And if a liquid came with a label, it is best to keep that original label with you as well. 

Frequently Asked Questions

Why can’t you take more than 100ml of niacinamide serum on a plane?

The 3-1-1 liquids rule was implemented in response to a 2006 liquid bomb plot. It was thwarted by British police two weeks before the intended attack.

For airlines, it’s difficult to discern if every type of liquid is a threat to passengers as they come through security checkpoints. Limiting liquids is a security measure to not only make passengers safer as they fly but to make security screening easier as well.

How strict is the TSA on liquids?

The TSA is incredibly strict on liquids. They are committed to ensuring all passengers are safe and there are no liquid explosives in carry-ons. Don’t try and get around the 3-1-1 liquids rule. It will just create more trouble for you as you’ll have to throw out any containers larger than 3.4 ounces. To make screening quick and easy, put your liquids in a separate bin as well. 

We have all been there standing in the security line with some item, for me it always seems to be a drink, and you realize you need to drink it fast or throw it away before you get to the TSA agents. 

It isn’t fun, but you need to comply. It’s not worth the hassle and time to try to sneak it through. 

Here is the TSA’s page on liquids. 

What does niacinamide serum do for my face?

By retaining moisture to the skin, niacinamide serum reduces the appearance of fine lines and wrinkles. By protecting the skin and keeping it hydrated, more skin cells can be produced, since the skin isn’t fighting for moisture. More skin cells means a smoother, plumper appearance.

Is niacinamide serum an exfoliant?

Niacinamide serum is not an exfoliant. It is a healer, a protector, and a plumper, similar to the ones your body produces naturally.

Recap and My Recommendations: Can you bring niacinamide serum on a plane? 

Niacinamide serum is permitted on planes. The TSA considers niacinamide serum, or products containing it, to be a liquid. Make sure you follow the airline’s liquid guidelines and bring the amount you need in containers that are no larger than 3.4 oz in your carry-on. 

You can bring multiple 3.4-ounce bottles so long as they all fit in one clear plastic Ziploc bag. They say to use quart-sized ones. I have always flown with the gallon-sized ones and never had an issue. 

And in your checked bags you can bring as much of it as you can safely transport.

Also, as you pack, consider creating more space in your bags by shipping it to your destination, buying it there, or ordering some online and shipping it to your final destination.
