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.

I use Hypnos drama. Will this product really make a difference?

Asked by: Rosie2
Yes, it absolutely makes a difference!  I rarely, if ever, go without using this lash primer. Not only does it make my lashes look full, but also it helps the mascara from settling on my lids. It makes a huge difference when it comes to thickening up your lashes. To be honest, I don't know think it has had long term benefits for my lashes, but I can 100% say that it makes my eyes look beautiful every time.  And if you really want a dramatic effect (think New Years Eve or a big event), apply it twice (primer>mascara>primer>mascara).
