Waterproof mascara exists, of course, but most women still prefer the regular, non-waterproof stuff, as it’s less of a struggle to remove. But what about those days — heat waves, thunderstorms, trips to the water park — that call for streak prevention? BareMineral’s Locked & Coated is a clear topcoat that you apply over mascara so it doesn’t budge. The mineral-rich formula won’t dry out your lashes or make them look clumpy or feel heavier. Keep it in your bag at all times: You never know when a summer rainstorm is going to pass through, or when you’ll come across The Notebook on TV.
