The sweat situation ALONE is a killer. You practically need primer for your primer. But nothing is as bad as accidental raccoon eyes. Sweat plus the oils on one’s skin combine to strip mascara off your eyelashes and deposit it firmly under your eyes. It’s not cute! But I’ve discovered the easiest, most foolproof way to stop your mascara from smudging all over your under eyes. And it uses something you probably already have in your makeup bag. I love Urban Decay Brow Tamer ($20, Sephora) in clear. I’m using Revlon Super Length mascara ($6, Target), which I freaking LOVE — the fat teddy bear brush make my lashes look super thick, and the formula is insanely black. Unlike waterproof mascaras, which you have to scour off your face, the gel-mascara combo comes off easily with makeup remover. For anyone who has delicate under eyes — hello, it me — this is a life-changer.
