Lancôme Cils Booster XL Enhancing Lash & Mascara Primer - Eyelash Primer

https://m.media-amazon.com/images/I/51GrLVY7scL.jpg
  • 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.

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.
