Why does my skin break out after flying on an airplane?

“Airplane cabins have very low humidity levels, which can increase transepidermal water loss and leave skin feeling dehydrated, tight, and dull,” says Dr. King.

Additionally, “Changes in climate, water quality, sleep schedules, diet, and stress can also disrupt the skin barrier and trigger breakouts, sensitivity, redness, or flare-ups of conditions like eczema and rosacea.”

Due to these factors, Dr. King suggests post-travel skincare should focus on hydration and barrier repair.
