5. Put on a sheet mask

There are few occasions more suitable for wearing sheet masks than on a long airplane ride. Sheet masks not only keep your skin hydrated, but the cooling effect will help wake you up and tone down puffiness. Keep one on for around 20 to 30 minutes for a refreshing reprieve from the stale cabin air.  If you feel a little self-conscious wearing one while seated next to a total stranger, you can always bring one of the long-wear gel types available Guardian and at Watsons. These are transparent, designed for overnight use, and can be removed with a tissue the next morning.
