Cosrx Acne Pimple Patches ($16)

Longer flights always manage to bring even my most deep-rooted zits to fruition; I'll hop on a flight with clear skin and walk off of it with three fresh pimples. To counter developing zits at the source, I turn to these hydrocolloid acne patches from Cosrx. They're transparent and match my skin's tone, so they aren't super noticeable. The set also comes with patches in multiple sizes, so I can choose the option that's best suited to my spots.
