What it is:
A lash-conditioning, mascara primer in the same great formula and new packaging that conditions and primes lashes to maximize results—creating even longer and more volumized lashes. 

What it does:
Give your lashes an XL boost. With just one sweep, this innovative mascara primer glides on and evenly coats and smooths your lashes to maximize the results of your favorite mascara. The magic behind this mascara base is the conditioning formula—infused with micro-fibers and Vitamin E— which adds extra length and thickness to lashes for added visible performance. White in color, it allows the black pigments to stand out from the clean base with more intensity than with traditional mascaras. 

What else you need to know:
CILS BOOSTER XL lengthens and thickens lashes to maximize the results of any mascara. Use CILS BOOSTER XL as a "lash mask" at night on clean lashes to nourish and rejuvenate.

New, never opened.
