What is Cils Booster XL Primer?

Cils Booster XL is an innovative all-in-one lash conditioner and mascara primer. Infused with micro-fibers, Vitamin B5, and Vitamin E, it evenly separates and coats lashes for maximized volume, length, and curl. An Allure Best of Beauty award winner!

How do I apply Cils Booster XL Primer for best results?

For the best results, apply the primer from roots to tips of clean lashes. Do not wait for the white formula to dry — coat with mascara immediately, until primer is no longer visible. For bolder results, apply two coats to both top and bottom lashes.

Why do I need a lash primer before mascara?

A lash primer creates a smooth, even base that helps mascara adhere better, building more volume, length, and curl. It also nourishes and conditions lashes over time, making them appear fuller, thicker, and healthier for a dramatic false-lash effect.

Why is the Cils Booster XL Primer formula white in color?

The primer’s white formula creates an ideal base allowing your mascara’s pigment to appear more vibrant and dramatic. It forms an even surface layer for a more dramatic finish, while the vitamin-infused formula keeps lashes feeling soft, never stiff.

Can Cils Booster XL Primer be used as a nighttime lash treatment?

Yes! This creamy, conditioning formula doubles as an overnight lash mask. Apply to clean, bare lashes before bed and allow to dry completely. It nourishes and rejuvenates lashes while you sleep, leaving them feeling soft and luxurious by the morning.

Lancôme’s number one lash-conditioning mascara primer glides on smoothly and evenly to create the perfect base layer before mascara. Designed to maximize the look of any mascara, Cils Booster XL helps add visible length, volume, and curl while keeping application bold, clump-free, and polished. Layer it under your favorite mascara for a dramatic false-lash effect that leaves lashes looking fuller, lifted, defined, and beautifully amplified from root to tip.
Infused with micro-fibers, Vitamin B5, and Vitamin E, this clump-free lash primer separates and coats each lash evenly from root to tip. Its white formula helps amplify mascara pigment intensity while conditioning lashes to feel luxuriously soft, never stiff or brittle. Wear under mascara to help boost visible length, volume, and curl while creating a smooth, even base for a bold, polished lash look with clean definition, amplified impact, and effortless drama.
In a consumer test with 103 women using Cils Booster XL with their regular mascara, 93% saw more length, 92% saw more volume, and 85% saw more curl. With continued use, this revitalizing lash primer visibly improves the look of natural lash thickness and curl over time. Use daily before mascara to help lashes appear fuller, lifted, and more defined with a bold, clump-free, false-lash effect and a soft, conditioned feel that looks polished.
More than 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. The conditioning formula helps lashes feel softer and healthier by morning, making it an elevated nighttime lash-care step as well as a smoothing primer before mascara during the day for lashes that look cared for, amplified, and beautifully prepared for mascara.
Sweep Cils Booster XL from root to tip to coat lashes evenly before mascara. Do not wait for it to dry before layering mascara on top. For best results, apply two coats to top and bottom lashes, then follow with your favorite mascara for added visible length, volume, and curl. As a nighttime treatment, apply to clean lashes before bed and allow the primer to dry before sleep so lashes feel conditioned, soft, nourished, and ready by morning.
