#R29 Pixi Glow Tonic, $29, available at Pixi. So, what makes Glow Tonic so rad? First of all, it's alcohol-free, so you don't have to worry about it drying out your skin. Quite the opposite, in fact. The aloe vera in this magic potion makes it super-hydrating. It also has ginseng to improve circulation, witch hazel to tighten things up, and a tiny bit of glycolic acid to exfoliate. Yes, the makers of Glow Tonic are generous.
