Lock it down.
Lip stain might sound like a lipstick gone wrong—stain???—when in fact, it's a formula gone very, very right. As a lip stain obsessive, I've tried many and have picked my ultimate favorites. The best vary in opacity (from sheer and just-bitten to completely impenetrable), finish (from high gloss to low-watt matte), and texture (solid, liquid, or gel), but have one common attribute: These babies are going nowhere fast.
