Ulta Raincoat Waterproof Mascara Topcoat, $10, has an asymmetrical brush: the shorter side allows you to coat your lashes with the clear formula, while the longer side combs through lashes to evenly distribute the product without clumping.

The water-repelling formula doesn't change the look or feel of your HG mascara -- no crunchy lashes here -- just be sure to give it enough time to dry (around 10 to 15 minutes).
