When travelling, the skin can become rather dehydrated. Often at times, the business, associated with travel can add stress, which also interrupts your skin's natural levels of moisture production. If flying, or spending more times outdoors, the water levels in the skin can also be robbed by recycled air and the environment (sun/ wind).
Are you a makeup hoarder? If you like makeup and have even done a little bit of experimenting, then you probably are! The thing about makeup is that often we buy things at the suggestion of others, from the sales person at a local beauty counter, or even on a whim online. Then we get it home and don't know what to do with it, or it looks different when we apply it ourselves.
