"If I come down with a bug and need to blow my nose a bunch, the skin above my lips always gets super dry. That’s why I always bring along a small container of Vaseline when I travel during cold and flu season, just in case. It soothes my irritated skin and can double as a hydrating overnight lip mask if you apply it there too. —Dana Leigh Smith, Vice President, Content Lead, Condé Nast Health"
