I Slept, Showered, and Worked Out In Tarte's Sweatproof Mascara to See If It Lasted

The first test I submitted this mascara to was an intense 45-minute boxing class. This was much more rigorous than my typical cardio routines of choice — I even ended up with bruises on my knuckles! — and I sweated pretty profusely. (You can see how red and, er, damp my face looks.) Despite this, my lashes held up without a trace of smudging or clumping.
