The latest skincare, makeup, and hair care innovations we're most excited to try this spring.

GLO Brilliant Personal Teeth Whitening Device

Lots of at-home whitening kits offer a brighter smile, but this hands-free gadget promises to do it faster, better, and with less sensitivity. The breakthrough is a sealed mouthpiece that combines heat and light to accelerate the whitening process and prevent whitening oxygens from escaping the surface of teeth.

The whitening gel applicators also deliver a superthick hydrogen peroxide gel that won't run off onto gums, meaning no sensitivity. Four eight-minute sessions a day will get your teeth up to five shades whiter in three to five days.

$275 (includes GLO mouthpiece and case, 40 applications of whitening gel, GLO control and dock, GLO lip care, power adapter, USB cable, and lanyard),
