5. WATER RETENTION
Sitting on a plane for hours on end can do a lot more damage to your skin than you think. Inactivity as well as consuming too much salt (through airport snacks like peanuts and chips) during a long flight can lead to water retention, which inevitably causes the face to puff up and swell, especially around the eye area. Stepping off the plane, your skin may look extremely tired around the eye contours and on the rest of the face.
To avoid the extra under-eye baggage, ensure that you stay hydrated throughout your flight, we suggest to get up and walk around every 20 to 30 minutes. If you are trapped in a window seat with sleeping passengers on either side, simply stretch and lift your legs up and down, rotating them in circles periodically. These exercises can help reduce water retention. Another tip is to stay away from salty plane food! All that salt will just increase water retention and add to the puffing of the face.
