Flying with cosmetics

Yes, but liquids, gels and creams are restricted in size. On most international flights each container must be 100 ml or less and packed in a clear resealable plastic bag. Anything larger should go in your checked luggage. Rules can differ slightly by country and airline, so check your airline and departure airport guidance before you pack.

Use one clear, resealable plastic bag with a capacity of one liter or less. Korean airport guidance often cites about 20 by 20 centimeters, though other sizes such as 15 by 25 centimeters are also listed. The rule is one bag per passenger, and it must close properly, so avoid overfilling it. Keep it where you can take it out quickly at security.

Usually not. Security screening generally looks at the container size printed on the bottle, not how much is left inside. A 150 ml bottle with only a little product can still be taken away at the checkpoint. Decant what you need into a small travel bottle of 100 ml or less, or pack the original in checked luggage.

Solid items such as bullet lipsticks, stick balms and solid perfumes are generally not treated as liquids. Lip gloss, liquid lipstick and mascara, however, can be classed as liquids or gels. If you are unsure about a product, simply put it in your clear liquids bag so screening goes smoothly and nothing gets taken aside.

A cushion compact holds liquid foundation soaked into a sponge, so some airports treat it as a liquid or cream. Its small size usually causes no trouble, but keeping it inside your clear liquids bag is the safer choice. If you are carrying several compacts and refills, split some into your checked bag.

Toiletry and cosmetic aerosols follow the liquids rule in the cabin, so each can must be 100 ml or less. In checked luggage, the usual limit is 0.5 liters per item and 2 liters in total per person, as of November 2026. Flammable or toxic products have separate restrictions, so check with your airline, and keep the cap on so the nozzle cannot be pressed.

Liquid cosmetics bought at airport duty-free shops are normally allowed in the cabin. The shop seals them in a tamper-evident bag (STEB) with the receipt inside or attached, and the exemption applies only if the bag stays unopened until your final destination, including any connections. Items bought at downtown or online duty-free stores are collected at the airport pickup counter.

It can happen. If you go through security again at a connecting airport, that country's rules apply, and duty-free liquids over 100 ml might not be accepted. Keep the sealed bag unopened, hold on to the receipt, and check the transfer airport's rules before you buy. Some travelers simply buy large liquids at their final stop.

Nail polish and remover count as liquids, so on international flights they must be in containers of 100 ml or less inside your one-liter clear bag. In checked luggage, personal toiletry allowances may apply, but this depends on the airline and the product's ingredients. Avoid large bottles of acetone, and check your airline's dangerous goods page before you go.

A cordless hair straightener with a non-removable lithium battery is, in principle, not allowed in either carry-on or checked bags. If the battery is removable, take it out and carry it in the cabin, and you can check the device body on its own. Exceptions and approval conditions vary by airline, so check your carrier's guidance before you pack.

Tighten each cap, wrap a layer of plastic film over the opening, and close it again. Put bottles in individual zip bags and tuck them between clothes to cushion them. Lock pump dispensers if they have a lock, and wrap glass bottles in a towel. Pressure changes in flight make loose caps more likely to leak.

Sheet masks are soaked in essence, so some airports count them as liquids. One or two in your clear bag rarely cause trouble, but if you are bringing home a large stack, checked luggage is the easier option. Pack them flat so the individual pouches do not burst under pressure or get crushed.

Medicines needed during the flight are often allowed even above 100 ml, but declare them separately at screening and carry a prescription or doctor's note. Rules vary by country and airport, so check ahead. For questions about using the medicine itself, talk to your doctor or pharmacist rather than relying on travel tips.

Each country sets a duty-free allowance and limits on what counts as personal use. Going over may mean declaring the goods and paying tax, and many units of the same item can look like goods for resale. Check the traveler allowance page of your home country's customs service before shopping.

Perfume of 100 ml or less can travel in your clear liquids bag in the cabin, while larger bottles must go in checked luggage. When treated as a personal toiletry, checked perfume is limited to 0.5 liters per item and 2 liters in total per person, as of November 2026. Wrap glass bottles well so they do not break during handling.

Use bottles that are washed and fully dried, and transfer products without touching them with your fingers. Label each bottle so you do not mix up toner and cleanser. Decanted products can spoil faster, so fill only what you need for the trip and clean the bottles again when you get home.

Korean domestic flights have been described as using different liquid rules from international flights, but security policies can change. Always check the latest guidance from your airline and airport, such as Gimpo or Jeju, before you fly. Restrictions on flammable items still apply on domestic routes.

Cabin air tends to be dry, so a travel-size moisturizer, lip balm and facial mist are usually enough. Keep them in containers of 100 ml or less inside your clear bag for easy access. Going lighter on makeup and drinking water regularly can help your skin feel more comfortable on a long flight.

Keep your liquids bag at the top of your carry-on and place it in a separate tray at screening. Pack anything over the limit in checked luggage from the start. Some airports now use scanners that let you leave liquids inside your bag, so follow the instructions given at the checkpoint you are using.

The most reliable sources are the security page of your departure airport and your airline's baggage and dangerous goods guidance. If you are connecting, check the transfer airport's rules too. When leaving Korea, the official guidance from airports such as Incheon is the reference point.
