Most people realize that flying can cause skin to dry out and breakout, but they may not know why. Whenever the environment is moisture-free (as with recirculated air in a plane cabin), the air actually draws moisture from wherever it can, including the skin. Dry skin will tend to get drier and oily skin will get even oilier to compensate for dehydration. To see just how damaging flights can be on the skin, I decided to conduct an experiment using a T-shirt and a small amount of water. I poured the liquid onto a 100% cotton T-shirt, then marked the time on a sticky note. On both the plane and in my hotel room, I watched until the water spot had virtually disappeared.
The difference in time between the two tests was astounding! Click over for the results, which may surprise you.
