This Double-Ended Mascara Perfectly Elongates My Top AND Bottom Lashes

Here's a full look at the Beauty by POPSUGAR Thick + Thin Mascara ($25). The cool thing about the double-ended tube is not only the brushes with different functions but also the distribution of the mascara itself. Since each brush pulls from its own supply of the same mascara, you can use the opposite end of the tube when you run out one side.

For example, if you use the thicker side a lot more often, you can still apply mascara with the thick brush by dipping it into the thin brush's side. Watch this Ulta video to get a full visual.
