The  technologically advanced mascara delivers incredible length and lash-by-lash separation in just one, quick step with its patented, dual-action precision brush. Lashes are surrounded from base to tip and from every angle. The brush’s flat interior gives lashes the appearance of being 60% longer, while the comb side defines and separates lashes. The no-clump formula features fine particles that go on smooth, as well as lash-conditioning Pro-Vitamin B5.
