Planning a trip soon and wondering whether you can bring your favorite deodorant or skincare products onboard? You’re not alone. Every year, thousands of travelers are caught off guard by airport security rules, especially when it comes to liquids, aerosols, and gels. This 2025 update is your ultimate guide to navigating TSA guidelines smoothly—without sacrificing freshness or peace of mind.

 

 

Understanding TSA's 3-1-1 Rule

What is the 3-1-1 Rule?

The TSA's 3-1-1 rule refers to:

  • 3.4 ounces (100 milliliters) per container
  • 1 quart-sized, clear, resealable bag per passenger
  • 1 bag per traveler

 

This rule applies to liquids, gels, aerosols, creams, and pastes—which includes most deodorants, skincare, and beauty products.

 

 

 

 

Types of Deodorants: What’s Allowed?

1. Stick Deodorants

Good news: solid deodorant sticks are not considered liquids and can be packed in both carry-on and checked luggage without restriction. AtomFresh Deodorant Balm is a TSA-safe option that comes in a compact, travel-friendly size—and it's aluminum-free and skin-friendly.

 

2. Spray Deodorants

These fall under aerosol rules. If the canister is under 3.4 ounces, it must be packed in your quart-sized bag. Anything larger goes in checked baggage.

 

3. Roll-Ons and Creams

Classified as liquids or gels, they must meet the 3.4 oz/100 mL rule and fit in your quart-sized bag. AtomFresh Cream Deodorant is compliant and designed for sensitive skin—perfect for long-haul flights.

 

 

What About Other Toiletries?

Body Wash, Lotions, and More

Products like body wash and hand lotion also follow the 3-1-1 rule. Opt for travel sizes of the AtomFresh Body Wash and Natural Hand Lotion to stay fresh without running afoul of TSA rules.

 

 

Expert-Backed Travel Packing Tips

1. Use Travel-Sized Containers

Transfer your products into TSA-compliant bottles or opt for brands that offer pre-measured travel sizes—like AtomFresh’s Mini Deodorant Starter Set.

 

2. Pre-Pack Your Quart Bag

Save time at security by packing your liquid items in a clear, zip-top bag and keeping it easily accessible.

 

3. Know What Goes Where

Keep liquids and gels in your carry-on for short trips and place larger quantities in checked baggage to avoid confiscation.

 

 

Recent TSA Policy Updates (2025)

While the 3-1-1 rule remains, TSA has improved screening technology in major airports, allowing more efficient processing of personal care products. However, random checks still occur, so compliance is essential.
