Great for both lashes and eyebrows. New additional tip brush so you can use this with lash extensions, comes with a mascara wand applicator rather than the usual tip wand applicator that only goes on the lash base. The mascara wand applicator applies the serum more fully (from the base to the tip of your lashes). For darker, longer, thicker feeling lashes. Perfect for use after removing eyelash extensions that may have damaged your natural lashes. Can also be applied to eyebrows that have been over plucked or are uneven.
