What it is
The #1 lash-conditioning and mascara primer all-in-one.

What it does
Plush, voluminous, healthy lashes can be yours with just a sweep of this innovative mascara primer. Gliding on smoothly and evenly, each coat creates an even surface layer to maximize the results of your favorite mascara. 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.

What else you need to know
Cils Booster XL takes your mascara one-step further. Multi-purpose, this creamy and conditioning formula, not only lengthens and thickens lashes, but can also be worn overnight as a “lash mask.”Simply apply on clean lashes to nourish and rejuvenate before bed.

Beauty Tip:
Apply the luxurious Rénergie Lift Multi-Action Eye Cream before using Cils Booster XL for a youthful, radiant, wide-eyed look.
Research Results:
In a consumer test on a panel of 103 women using Cils Booster with their daily mascara:
- 93% of consumers saw more length
- 92% of consumers saw more volume
- 85% of consumers saw more curl

Benefits:
Works as a lash conditioner to nourish and condition eyelashes, while maximizing volume. Doubles as a lash primer by coating clean eyelashes smoothly, to provide an ideal base for clump-free mascara application.
As A Base Coat For Mascara:
- Apply from roots to tips of eyelashes, but, do not wait until Cils Booster XL is dry before coating lashes with mascara.
- Coat lashes with mascara for desired look, or until white primer is no long visible.
- For a optimal color, intensity and a false-lash look, apply two coats of eyelash primer to bottom and top lashes, before applying mascara.

As A Nighttime Eyelash Conditioner:
- After cleansing face, and finishing normal nighttime beauty routine, apply Cils Booster XL to bare lashes.
- Allow to dry properly before sleep.

Store in a cool, dry place.

Rated 5 out of 5 by from Amazing! This eyelash primer not only lengthens my eyelashes but also keeps my black Hypnose mascara where its supposed to be. My lashes look long and full and the black stays on my lashes instead of running off to my skin under the eye. (I have oily skin.) No need for false eyelashes now!

Rated 5 out of 5 by from Essential for Enhancing Lashes I've been using Cils Booster for years under my Lancome mascara because it gives the maximum boost of thickness and length while moisturizing my lashes so there isn't any lash loss. Only beautiful enhancement of my natural lashes. Thank you Lancome.
