Can You Bring Sunscreen on a Plane?

Yes, with conditions depending on the format. Liquid and lotion sunscreens must follow the 100 ml rule. Solid mineral sunscreen sticks are not liquid and have no size restriction in carry-on. Format is the deciding factor.

Sunscreen Format and the 100 ml Rule

Airport security classifies products by physical state, not product category. The key question is: is it a liquid, gel, paste, or solid?

Sunscreen format	Classified as	100 ml rule	Size limit
Lotion / cream sunscreen	Liquid	Yes	100 ml or under
Sunscreen spray (aerosol)	Liquid	Yes	100 ml or under
Gel sunscreen	Liquid	Yes	100 ml or under
Tinted sunscreen moisturiser	Liquid	Yes	100 ml or under
Mineral sunscreen stick	Solid	No	Any size
Powder sunscreen (brush applicator)	Solid	No	Any size

The Biggest Mistake Travelers Make

The most common sunscreen mistake at airport security is bringing a "travel size" bottle that is actually larger than 100 ml. Many sunscreens sold as travel sizes are 150 ml, 177 ml (6 oz), or 200 ml — all of which exceed the limit and will be confiscated.

The rule applies to the container size, not the amount of product inside. A 200 ml bottle that is only 30% full still violates the rule. Security officers cannot make exceptions based on remaining volume.

What 100 ml looks like: a standard 100 ml container is roughly the size of a small hotel toiletry bottle. Coppertone Sport SPF 50 travel size (89 ml) and Neutrogena Ultra Sheer (88 ml travel bottle) both comply.

The Solid Stick Advantage

Solid mineral sunscreen sticks are genuinely unrestricted. Because they are solid, they do not go in the liquids bag and there is no size cap.

Popular solid options that work well in carry-on:

• Colorescience Sunforgettable Total Protection Brush (powder, brush applicator — solid, unlimited)
• Supergoop! Shimmershade (solid)
• Blue Lizard Mineral Sunscreen Stick (stick format)
• Sun Bum Mineral Sunscreen Face Stick SPF 50 (stick format)

These are also reef-safe options, relevant if you're travelling to marine destinations in Hawaii, Mexico's Yucatan coast, or the Caribbean where chemical sunscreen use on reefs is restricted or banned.

How to Pack Liquid Sunscreen in Carry-On

1. Ensure the bottle is 100 ml or less — check the label
2. Place it in your 1-litre resealable clear plastic bag along with other liquids
3. You are allowed one such bag per person
4. Remove the bag from your carry-on at the security checkpoint

If you need more sunscreen than your liquids bag allows, consider: buying sunscreen at your destination, using a solid stick in carry-on and checking a larger bottle, or packing full-size bottles only in checked luggage.

Buying Sunscreen at Your Destination

At beach and sun destinations, SPF products are readily available locally. Sun cream is sold in pharmacies, supermarkets, and resort shops throughout the Mediterranean, the Caribbean, Southeast Asia, and Hawaii. Buying there avoids any liquids-bag stress entirely.

The main risk with buying locally is variability in SPF standards — some markets sell products with different formulations or labelling conventions. If you use prescription or mineral-only formulas, bring what you need rather than relying on finding it.

Checked Luggage

Any size of any sunscreen format can go in checked luggage. If you are checking a bag, simply pack your sunscreen there. For carry-on-only travel, the solid stick or buying locally are the simplest solutions.
