Beauty Gadgets?

There are all sorts of beauty gadgets out there now promising to lessen acne, zap wrinkles, lift cheekbones, and more. My favorite ones though are those that you might not expect. For example, my Korean-American neighbor, who has gorgeous skin, got us hooked on Coway, which is a hardcore water filtration device plus service that's originally from South Korea. She even washes her face with Coway filtered water. Another gem: I recently interviewed Ruby Rose for a story and she travels with a mini Muji humidifer that she plugs in at the hotel room. Paired with a sheet mask, it's a travel beauty gamechanger.
