Lancôme's number one lash-conditioning mascara primer. Gliding on smoothly and evenly, it creates a perfect base layer that maximizes the results of any mascara — adding visible length, volume, and curl for a bold, clump-free, false-lash effect.
Infused with micro-fibers, Vitamin B5, and Vitamin E, this clump-free formula separates and coats each lash evenly. White in color, it amplifies mascara pigment intensity while conditioning lashes to feel luxuriously soft, never stiff or brittle.
Clinically validated performance: in a consumer test with 103 women, 93% saw more length, 92% saw more volume, and 85% saw more curl. Over time, this revitalizing primer visibly improves natural lash thickness and curl with continued use.
More than just a mascara primer — Cils Booster XL doubles as a luxurious overnight lash mask. Apply to clean bare lashes before bed to nourish, condition, and deeply rejuvenate lashes while you sleep. Wake up to visibly softer, healthier lashes.
Apply from root to tip. Do not wait for it to dry before layering mascara. For best results, apply two coats to top and bottom lashes before your mascara. As a nighttime treatment, apply to clean lashes before bed and allow to dry before sleep.
