Traveling on flights pose quite a few discomforts - in addition to the interruption of turbulence and jet lag, low humidity and low air pressure within the cabin environment also cause physical discomforts. Being stuck in a narrow seat and an enclosed cabin for long durations also increases the chances of skin dehydration, as the in-flight humidity is on par to desert dryness! In environments like this, the fastest way to replenish skin hydration is to throw on a facial mask with concentrated serum to restore your glow!
The average humidity in the United States is about 50-60%, while only 10-20% in the desert. The humidity of high-altitude air in-flight is also around 10-20%, sometimes even dropping close to 0%! Due to the dry air in flight cabins, your eyes, nose, and throat often experience dryness, so does your skin. Hence, it is highly recommended to drink more water in-flight and pay attention to skin moisturizing, to ensure that fine lines and dry/flaky skin do not surface.
