Yes, you can bring sunscreen on a plane, in a carry-on or a checked bag. In a carry-on, TSA limits each container to 3.4 ounces (100 mL) or less, packed in your one quart-size liquids bag; larger containers, even part-empty ones, go in a checked bag. That holds for lotion, cream, gel and spray alike.
Most of the confusion sits at the edges of that rule: what counts as a liquid, what a spray adds, and where sticks fit. Sprays are treated like lotion in the cabin but carry one extra rule. And TSA has published no separate rule for sticks.
This article sets out what the Transportation Security Administration and the Federal Aviation Administration publish for each form of sunscreen, read on 23 September 2026, with the Canadian and UK rules for comparison. Where the agencies say nothing, it says so.
Is sunscreen a liquid for TSA?
Yes. TSA's liquids rule covers "liquids, aerosols, gels, creams and pastes", which takes in lotion, cream, gel and spray. TSA also lists sunscreen by name in its What Can I Bring? tool: allowed in carry-on bags at "less than or equal to 3.4oz/100 ml", and allowed in checked bags.
Face lotion counts too: TSA's liquids FAQ names lotion among the everyday items the rule covers.
That one entry covers all sunscreen, without separating lotion from spray or cream from gel, and it ends the way every entry does: the final decision rests with the TSA officer. Nor is sunscreen among the rule's listed exemptions, which are medications and infant and child nourishment.
TSA's own site once said otherwise. In April 2021 TSA noted that the site had "incorrectly reported that sunscreen containers larger than 3.4 oz. were allowed in carry-on bags, if medically necessary", and fixed it. So a sunscreen bottle over 3.4 ounces goes in the checked bag.
How much sunscreen can you bring in a carry-on?
As many containers as fit in one quart-size bag, provided each holds 3.4 ounces or less. TSA sets no count of bottles. It calls this the 3-1-1 liquids rule, and its travel checklist gives the three numbers:
- 3.4 ounces or less per container (100 mL)
- 1 quart-size bag, clear, plastic and zip-top, with all your liquids inside it
- 1 bag per passenger
The limit is on the container, not on what is left in it. TSA's own diagram puts it plainly: containers larger than 3.4 ounces go in checked baggage "regardless of amount inside". A 6-ounce bottle with an inch left in the bottom is still a 6-ounce bottle at the checkpoint.
The rule is about containers, not brands. TSA's sunscreen entry names no products, and for carry-on bags it sets only a size, so what counts at the checkpoint is the number on the container.
Single-use packets follow the same rule: each one is its own container, and every one goes in the one quart-size bag with your other liquids.
Can you take full-size sunscreen through TSA?
Not in a carry-on; yes in a checked bag. TSA's 2021 statement advised passengers who need larger quantities of sunscreen to "add them to checked baggage for use at their destination".
Checked bags have limits too. TSA's sunscreen entry and the FAA's PackSafe page both give them for medicinal and toiletry articles, a group that includes sunscreen along with things like hairspray and shaving cream.
The limits: 2 kg (70 ounces) or 2 L (68 fluid ounces) per person for all of those articles together, and 0.5 kg (18 ounces) or 500 mL (17 fluid ounces) for any one container.
The FAA's PackSafe page cites the federal rule they draw on, 49 CFR 175.10(a)(1): the exception that lets passengers carry medicines and toiletries, aerosols included. Pack to those figures: keep each checked bottle at 17 fluid ounces or less.
A spray's nozzle must be capped in the hold, as in the cabin. Bag a checked bottle on its own, so a spill stays off your clothes.
Can you bring spray sunscreen on a plane?
Yes, in either bag, with one extra rule: a capped nozzle.
- In the cabin: 3.4 ounces (100 mL) or less a can, in your quart-size bag.
- The nozzle: the FAA requires the release device, the button or nozzle, to be protected "by caps or other suitable means to prevent accidental release". Keep the cap on, and do not pack a can whose cap is lost.
- Why it is allowed at all: the FAA forbids flammable aerosols that are not medicinal or toiletry articles, such as spray paint, in any bag. Sunscreen is named on its list of medicinal and toiletry articles.
Can you bring a sunscreen stick in a carry-on?
Yes, at 3.4 ounces or less. TSA has not published a separate rule for sticks. Its list has one sunscreen entry, and that entry does not distinguish a stick from a lotion. These are the entries that bear on the question, from all 495 on TSA's list:
| TSA entry | Carry-on bags | Size given | Last updated |
|---|---|---|---|
| Sunscreen | Yes | 3.4 oz (100 mL) or less | 29 Mar 2023 |
| Deodorant (Solid) | Yes | None given | 30 Mar 2017 |
| Lipsticks | Yes | None given | 1 Sep 2017 |
| Stick or solid sunscreen | TSA has no entry for this | ||
TSA lists solid deodorant and lipstick as allowed in carry-on bags with no size given; it has no such entry for stick or solid sunscreen. Its liquids rule covers creams and pastes.
So an officer could treat a stick like solid deodorant or like a cream under the liquids rule, and the officer has the final say. A stick of 3.4 ounces or less, packed in your quart bag, meets the rule under either reading; a larger one is a question you would be settling at the checkpoint.
How much sunscreen does a trip actually need?
More than a carry-on usually holds. The American Academy of Dermatology says most adults need about 1 ounce, roughly a shot glass, or 30 mL, to cover the skin clothing leaves bare.
For the face it says at least a teaspoon, and it advises reapplying every two hours and after swimming or sweating. A teaspoon is about 5 mL.
Run that for one adult on a six-hour beach day: one application on arrival and one every two hours after it makes three, so at least 3 ounces, about 90 mL.
That is most of one 3.4-ounce bottle, for one person, for one day, before any extra coat after a swim.
Those amounts may look large: the Academy notes that many people apply only 20 to 50 percent of the amount needed to reach the SPF on the label.
So the quart bag covers the flight and the first day. A week of full-body use needs a full-size bottle in the checked bag, or one bought on arrival.
The rules for each common form, side by side
Every common form follows the same two rules: 3.4 ounces a container in the cabin, and the limits on TSA's sunscreen entry in the hold. Only the nozzle and the sticks differ.
| Form | Carry-on bag | Checked bag (per TSA's sunscreen entry) | What differs |
|---|---|---|---|
| Lotion or cream | 3.4 oz (100 mL) or less a container, in the quart-size bag | Yes, up to 17 fl oz (500 mL) a container | Nothing: this is the standard case |
| Gel | 3.4 oz (100 mL) or less a container, in the quart-size bag | Yes, up to 17 fl oz (500 mL) a container | Nothing |
| Spray (aerosol) | 3.4 oz (100 mL) or less a can, in the quart-size bag | Yes, up to 17 fl oz (500 mL) a container | Nozzle must be capped |
| Stick or solid | No separate TSA entry; 3.4 oz or less is the safe choice | Yes, up to 0.5 kg (18 oz) by weight a container; no separate stick rule | TSA has not ruled on sticks |
| Single-use packets | Each packet is its own container, in the quart-size bag | Yes, well under the 500 mL container limit | Nothing, if each is 3.4 oz or less |
| Any container over 3.4 oz, even part-empty | Not allowed | Yes, up to 17 fl oz (500 mL) | Capacity counts, not contents |
How to pack sunscreen for a flight
Split it: small containers in the quart bag, the rest in the checked bag. In order:
- Work out the cabin share: the flight plus the first day, by the arithmetic above.
- Carry-on: containers of 3.4 ounces or less, whether a small bottle, a capped spray or single-use packets, in your one quart bag with all your other liquids.
- Checked bag: a full-size bottle, no larger than 17 fluid ounces (per TSA's sunscreen entry), cap on, bagged on its own.
- Flying carry-on only: everything must be 3.4 ounces or less and share the one bag,
so bring what covers the first days and buy more on arrival. By the
arithmetic above, a week of six-hour days is at least 21 ounces for one adult, more
than six 3.4-ounce containers, before any of your other liquids.
This is what Solvyn Shield is made for: sealed 5 mL packets that go through security in your liquids bag. They are a carry-on and top-up format, not a week's supply. Shop Solvyn Shield.
- For the face: at least a teaspoon each time, by the Academy's measure.
- Storage: follow the storage direction on your sunscreen's label.
- Flying to Hawaii: the state restricts which sunscreens may be sold there, which matters if you plan to buy more on arrival. This summary of Hawaii's sunscreen law quotes the statute, and this guide to reef-safe sunscreen in Hawaii covers what that means for a trip.
What size sunscreen can you take on a plane in Canada or the UK?
The same 100 mL a container as in the US: Canada sets 100 mL / 100 g, and most UK airports allow sun cream only in containers of 100 mL or less. The bag differs, and in the UK the rules depend on the airport.
| Where you fly from | Container limit | The bag | Worth knowing |
|---|---|---|---|
| United States (TSA) | 3.4 oz (100 mL) | One quart-size bag per passenger | Part-empty containers still count by size |
| Canada (CATSA) | 100 mL / 100 g (3.4 oz) | One clear, resealable bag of no more than 1 L per passenger | Lists creams, lotions and sunscreen spray as liquids and aerosols |
| United Kingdom | 100 mL at most airports | No more than 1 L, about 20 cm by 20 cm, one per person, where the airport asks for one | Some airports may allow containers up to 2 litres; check each one |
The UK government's advice is worth following anywhere: check the rules at the airport you fly from, any airport you pass through, and on the way home.
Where a 5 mL packet fits
We make Solvyn Shield, labeled as Solvyn Mineral Sunscreen SPF 50: a broad spectrum SPF 50 sunscreen whose only active ingredient is zinc oxide at 17.50%, water resistant for 80 minutes, in sealed single-use 5 mL packets. By the arithmetic above, that is a carry-on and top-up format, not a beach-day supply.
5 mL is also about the teaspoon the Academy gives as a minimum for the face, which makes one packet a sensible unit for the face, including each reapplication.
What it does not do is cover a whole body. The Academy's minimum ounce is about six packets, and the label says to reapply at least every 2 hours, after 80 minutes of swimming or sweating, and immediately after towel drying.
Three more directions from the label: apply liberally 15 minutes before sun exposure; children under 6 months of age, ask a doctor; and protect the product from excessive heat and direct sun, so carry packets in a shaded bag, not on a car dashboard.

A note on scope. This article covers airport security screening in the United States, with Canada and the UK for comparison, as the agencies' pages read on 23 September 2026.
TSA's sunscreen entry was last updated on 29 March 2023.
The agencies revise those pages, and TSA officers make the final decision at the checkpoint, so check the sources before you fly. Nothing here is medical advice.
Solvyn makes a mineral sunscreen in single-use packets, so we have an interest in this question.
That interest has not shaped the rules above: each is sourced to the agency that sets it, and the dose arithmetic to the American Academy of Dermatology, including the part that shows packets are a carry-on and top-up format, not a full beach-day supply. If a carry-on and top-up sunscreen is what you need, you can see Solvyn Shield's packets and prices.
