What It Is: A raincoat for lashes - this long-wearing, waterproof mascara defines, curls, and lengthens lashes without smudging, clumping, or flaking. Wear it alone or layer over any Bobbi Brown mascara formula to make it instantly waterproof. Why It's Different: The buildable formula creates natural to dramatic looks depending on how many coats are applied. The patented brush coats individual lashes evenly. Product Usage: Brush through lashes, starting at the base of the lash line, working up the length of lashes to the tips. Apply a second coat if desired. Remove with Instant Long-Wear Makeup Remover.
