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 2 out of 5 by from Works, but extra step in morning process. I received this as part of a promotional discount. While it does add volume and length to my lashes, it didn’t fit in with my low-key approach to beauty.

Rated 5 out of 5 by from Lashes are longer! I’ve been using this lash primer for two years and love it. It helps mascara look and wear better. Since caring for my eyelashes with the primer my lashes are visibly longer.

Rated 5 out of 5 by from No clumping and lashes look dramatic I bought this a little over a week ago and I love how it makes my lashes look. I have paired it with Monsieur big mascara and another brand mascara and it works very well. As for the claims that it will improve lash thickness and curl overtime, I have not used it long enough to notice a difference yet.

Rated 5 out of 5 by from Wow I received this as a gift with purchase a few weeks back. I hadn’t even tried it until today because I was skeptical. I’m 69 and my lashes have become sparse and they aren’t brown anymore. Well let me tell you. I was stunned at the result. I love it and it’s very natural looking. I’ll be buying this going forward. I love it.

Rated 5 out of 5 by from Makes a big difference! This works so well! It makes a huge difference in how full and long my lashes look when I use as a base for my mascara. Just wish it wasn’t so expensive.

Rated 5 out of 5 by from Employee Destiny Lakewood,CA I went into buy my usual facial foundation (MACY'S Lakewood,CA.) Destiny was very courteous and prompt in attending to my needs. She gave great input on lip stick color for me when I asked. She was great, no pressure and professional. She is an asset to Macy's Lanc�me :-)

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!
