Airport duty-free versus Olive Young for K-beauty 면세점 vs 올리브영

Duty-free wins on some luxury Korean brands and on liquids you would rather not carry through the city. Olive Young wins on drugstore textures, viral sunscreens, and the ability to test. Prices and sets change. Compare the exact SKU, not the brand name. Tax refund downtown is a different process from duty-free.

What duty-free is good at

Sealed full-size luxury, some exclusive kits, and not walking around Seoul with 200 ml of toner. You still need time at the airport.

What Olive Young is good at

Mass-market K-beauty, frequent restocks of trending SPF, membership coupons, and testers. You can return to the hotel and decide.

Fakes

Neither official channel is a street photocopy stall. The risk is parallel grey goods and old stock, not a cartoon fake, if you stay official. Check PAO and manufacture marks anyway.

Liquids at security

Downtown purchases still face TSA-style limits on the way home unless they go in hold luggage. Duty-free bags have their own rules after screening.
