No amount of moisturizer can make up for the damage that dry and stuffy indoor air wreaks on sensitive skin each winter. Instead of slathering on extra layers of lip balm or hand cream, pump hydration into the air itself. A simple and sleek humidifier from VicTsing will do the trick. Though it may look small, its reservoir can hold up to 300 ml of water, enough to keep it running continuously for ten hours. For an added bonus, this winter lifesaver doubles as an essential oil diffuser, meaning you can bring a spa-like ambiance to any room with a couple drops of lavender, orange, or peppermint oil. Available on Amazon; $43.99.
