Want long lashes one day and curled, voluminous ones the next? This mascara's dual-bristle brush lets you customize your look to lengthen with its thicker side or curl and volumize with the thinner one. Amp up the intensity to match your mood or the occasion by using both for fuller, defined lashes. And you won't need to fear any clumping or flaking; the formula's infused with collagen, peptides, and keratin to strengthen each lash and make them all appear thicker.
