FORCES OF NATURE

eyeliner that survives rain, sweat, and really late nights.

When Tarte first introduced its Amazonian Clay collection several months ago, it claimed that the key ingredient made these products last longer than ever. We gave the blush a spin back in February, and noticed that even with a powder base, the rosy color held steady all day.

For summer, the brand's debuted a new series of eyeliners with the same concept. Packaged in mini pots with a tiny brush included, emphasEYES comes in six different wearable shades. They're easy to apply, smudgeable at first (if you don't want your eyeliner to look too perfect), and last forever.

Besides the clay, ingredients like natural plant waxes ensure that your liner isn't going anywhere once it's dry. We gave the black version a test-drive on one of the muggiest days of the season, and it lasted all day (it even stayed on during our workout, which is really saying something).

This super waterproof quality means that you'll need spend a few extra minutes removing the liner at night. But if you ask us, that's a small price to pay.

After all, it's going to be a hot summer.
