Best Long-Lasting Mascara

Winner

Lancôme Définicils High Definition Mascara, $24

A favorite for its lengthening and separating properties, this mascara has the staying power of super-hold hair spray but still washes off. "Two coats at 8 a.m. and I didn't have to think about it until 11 p.m.," said a tester.
