With a conditioning formula for visible performance, infused with micro-fibers, Vitamin B5 and Vitamin E, lashes appear longer and fuller. This revitalizing lash primer will improve lash results, thickness and curl over time. White in color, Cils Booster XL leaves lashes feeling luxurious and soft, while allowing the pigment of your favorite mascara to stand out, thus, creating an intense and rich false-lash look.
