IF YOU’VE EVER considered using a pumice stone to slough dead skin off your lips, you can stop. MAC‘s Prep+Prime Microfine Lip Refinisher ($14.50, MAC stores) is basically just that. One half of the stick is grit, the other is vanilla ChapStick.

We tested it via a toothbrush (often recommended for this purpose by makeup artists) and an actual piece of pumice. The results were good in comparison — the toothbrush left a lot of skin and the pumice stone hurt. Sanding off skin with this thing took longer, but the results were less traumatic.
