Use a Humidifier on a Regular Basis
A lot of skin issues can be resolved by keeping your skin hydrated — regardless of whether your skin is oily, combo, or dry. One easy trick is to keep a humidifier by you whenever you get a chance. The Hey Dewy Portable Facial Humidifier ($39) makes it easy for the air around you to stay moist because it's only six inches tall and powered via USB. You can plug it into your computer while you work or in your car while you drive and, my personal favorite, you can use it on a long plane ride to keep your skin feeling fresh.
If you live in a drier climate or just generally want your home to feel more humid, consider investing in a room humidifier like the Dyson Air Multiplier AM10 Hygienic Mist Humidifier ($500). Use it while you sleep or while you're working at home so you can keep your skin feeling fresh and bouncy.
