What it is: A two-step lash fortifying system for creating 25% longer, thicker lashes in just two weeks. What it does: In combination, these two products create longer, thicker lashes that resist loss and breakage. The clear gel-like serum accelerates the growth of your lashes with peptides. Use the tiny brush to apply it at your lash line. It penetrates at the root and stimulates keratin to lengthen, thicken, and fortify your lashes. The conditioning mask applies with a wand and loads your lashes with growth peptides and high potency ingredients like Panthenol and Vitamin E.
