5. Lip Balm
Lip balm is an important travel companion for both men and women. The dehydrating atmosphere of planes, the weather at your holiday destination (whether it be hot or cold), and the salty snacks that are usual on offer during transit, all act together to dry your skin and lips. As an added bonus lip balm can also be used as skin moisturizer in an emergency, in order to protect your face from especially harsh weather.
