Look Sexy All February Long With These Beauty Must Buys

I'll admit I didn't think that my run-of-the-mill toothbrush needed an upgrade until I saw the Issa in action. One charge lasts for 200 uses, and not only do the silicone bristles scrub better than my standard nylon ones, but they also don't hold on to disgusting germs! I use the child-size toothbrush ($119) because it's perfect for my small mouth — and I like the smiley face that lights up, telling me when I've brushed for the dentist-recommended two minutes. (Don't judge!)
