Take five products: a gentle cleanser, one moisturizer, one broad-spectrum sunscreen, one occlusive balm and one treatment you already use at home. Everything else either repeats a job those five already do, or gets opened once and left in a hotel bathroom.
What decides the list isn't your skin, it's your luggage. For US flights, the TSA allows one quart-sized bag of liquids, gels, creams and pastes in your carry-on, with each container 3.4 ounces (100 milliliters) or less. The limit applies per container, so a big bottle that's mostly empty still doesn't pass. Solid formats help: a balm in a tin and a cleansing bar don't fight the bottles for space.
The five, and what each one covers
- Cleanse
- One fragrance-free cream or gel cleanser that doubles as a body wash
- Hydrate
- One moisturizer for the face, neck, hands and after sun. A cream rather than a lotion if the air is dry
- Protect
- Broad-spectrum SPF 30 or higher, per the AAD. Check the label for water resistance if you swim
- Seal
- A petrolatum-based balm for lips, cuticles, heels and windburn. Solid, so it skips the liquids allowance
- Treat
- One active you already tolerate, at the frequency you already use it. A trip is not the week to start something new
At a glance
The rule behind the five is that nothing overlaps. A toner, an eye cream and a sheet mask each do something the moisturizer already does, and each is another bottle and another morning decision.
How much to bring
Sunscreen decides the packing, because it's what you use the most of and what runs out first. Face and neck alone take a good squeeze every morning, and the AAD's figure for covering exposed body skin is about an ounce, a shot glass, per application. If you're swimming or in a swimsuit all day, one small bottle won't stretch. Everything else fits easily in small jars.
Fourteen days, roughly measured out
| Product | Rough daily use | Over two weeks | Pack this |
|---|---|---|---|
| Cleanser | A small squeeze, twice | A small travel bottle | A container under 100ml |
| Moisturizer | A small amount, morning and night | A 50ml jar is plenty for most faces | A 50ml jar |
| Sunscreen | Face and neck daily, more for body | The most of anything | The biggest container you can carry on. Buy more there if you swim |
| Occlusive balm | A fingertip | A little | A small tin, out of the liquids bag |
| Treatment | A few drops at night | A little | The original bottle if it's 100ml or less |
| Total | Small amounts, except sunscreen | Well under the limit | One quart-sized bag |
What stays at home
- Toner — Water with a marketing budget. The moisturizer does the hydration in one step, and the second bottle never leaves the bag.
- A separate eye cream — Usually the same kinds of emollients in a smaller jar for more money per milliliter. Moisturizer patted on with your ring finger does the job.
- Sheet masks — One use, a lot of packaging, and a benefit that lasts until the morning. A cream you already own does more.
- An exfoliating acid — Travel is when the barrier is most fragile: different water, dry cabin air, more sun. Leave the acid at home and take nothing new.
- The second cleanser — Unless you wear heavy makeup, one cleanser plus water is the whole routine. Two versions of one product is how a bag stops closing.
Packing the bag in five moves
- 1
Decant into small labeled bottles
Every unlabeled bottle looks the same at security, including to you at six in the morning. A strip of tape with the name is enough.
- 2
Don't fill to the brim
Leave some headroom. Pressure changes and warm rooms can push liquid out, and one leak coats everything in the bag.
- 3
Squeeze the air out of tubes before capping
A tube that is half air pushes product out on the first ascent. Roll from the base, squeeze, then close it tight.
- 4
Keep the solids out of the bag altogether
A balm in a tin, a cleansing bar and a sunscreen stick are solids, so they don't eat into the quart bag. Final calls belong to the officer at the checkpoint.
- 5
Bag it twice, and put it on top of the case
One zip bag inside another, at the top where you can reach it if the bag is gate-checked.
The five, and what to buy
A two-week kit
Sizes are chosen so that almost nothing needs decanting, which is the point of the exercise. Prices are shown only where we confirmed them on the brand or retailer page in Oct 2026.

The Ordinary
Azelaic Acid Suspension 10%, 30ml
A tolerant active for acne and the marks it leaves, and a sensible travel pick because you can keep using the one you already know.
Check priceIf the trip runs longer than two weeks
Past two weeks, stop trying to carry everything. Take enough for about ten days and buy the rest there: cleanser, moisturizer and sunscreen are the categories where a local version is usually fine, and a lighter bag beats brand loyalty.
The one product worth carrying past its travel size is the treatment, because actives are where changing brand mid-trip is most likely to cause trouble. It is the only part of the kit that has to be the one from home.
