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 Volumize and repair!?! I have been using the CILS primer for 4 years, and I will never try another! Vitamin B5 and vitamin E help repair and condition lashes, while protecting your lashes from mascara. My lashes were damaged from extensions, and CILS saved them!

What ingredient in this product curls your lashes? My lashes are very straight until I apply this product. What a change! Is there a mascara that curls lashes?

Quantity diff in Cils Booster XL and travel size

I notice the travel size is the same price at the XL. Do they contain the same amount of Primer, just different size packaging? Just curious because my sample size seemed to last as long as the full size I purchased in the store?
Asked by: Miami Girl
The travel size does last a long time but it's only $13, not full price

Is this product waterproof?

If I put this under my waterproof mascara and go swimming, will it stay on? Or will all my mascara run?
Asked by: Sarah
No. The Cils booster is not waterproof. If you use waterproof mascara it will not come off, but with regular mascara, it washes off easily.

Is this safe for contact lens wearers?

Asked by: Cindy O
I've never had a problem with it. I always put my contacts on before my makeup and later remove contacts before removing makeup. I hope this helps!

Help! I'm confused, apply wet or dry?

I've been reading through all of the questions and answers and ended up a little confused. Some of you say to wait until the booster is dry before applying mascara and others say to apply mascara just after, while still wet. So when is the appropriate time to apply, dry, damp, or wet? And if I may ask one additional question? I read that the booster has 'fibers' in it. I tried a fiber mascara once #another brand# and the fibers feel into my eyes, badly. Has anyone had any issues with this? I don't really need volume, but I do definitely need length. Thank You!
Asked by: Cateyes
Apply it to your lashes straight from the tube, before you apply mascara. Do give it a minute to dry. Prepare to be amazed!
