Why you’ll love it: Coffee, Diet Coke, and this eye treatment have more in common than you’d think. They’re all packed with caffeine to instantly jolt you (and your undereyes) awake after late nights, long meetings, and puffy mornings.

How you’ll use it: Press the pump to distribute the lightweight gel, then gently press the ceramic tip to the undereye area, lightly massage in a circular motion, and pat in any excess product.
