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 Fave This is my absolute favorite. Natural wear, long lasting and bold. I won't wear mascara without applying this base first. Applying the base is what I focus on the most. Starting at the very base of lashes to keep the natural curl and cover each lash. Then applying mascara is very quick, easy and simple.

Rated 5 out of 5 by from THIS product is a WINNER!!! What I LOVE about Lancome's Cils Booster XL Enhancing Lash Primer, is that there is no clumping whatsoever, and an immediate, almost instantaneous, thickening of the eyelashes, upon impact.

Rated 5 out of 5 by from Adds instant volume and length I’ve been using my booster for years. I won’t use mascara without it. It adds instant volume and length. It’s like an entirely different outcome If I don’t use it. As a middle aged woman we need more volume. People have even asked if my lashes were fake before!

When I apply the booster, do I let it dry before applying Mascara?

Asked by: JOANN T
Hi there! When using our Cils Booster XL Enhancing Lash Primer, we recommend applying our from roots to tips of eyelashes, but, do not wait until Cils Booster XL is dry before coating lashes with mascara. Then, you can coat the eyelashes with mascara until the white is no longer visible. We wish you great success when using this product!

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!

Apply it to your lashes straight from the tube, before you apply mascara. Do give it a minute to dry. Prepare to be amazed!

how do i take it off? And if i leave it on at night should i take it off and reapply again?

Asked by: AgentLarold
Effacil or Bifacil are must-haves for removing mascara. Effacil is emollient-free and removes regular mascara. Bifacil has emollients that make it great for waterproof mascara and lip stains. Cils Booster has two awesome uses. First, because it is vitamin enrixhed, you can use it as a mask for your eyelashes and brows while you sleep. Simply apply at night on clean lashes before bed. In the morning, wash your face completely. Reapply for boosting effects before applying mascara. Very simple!

Can I use it only as a lash serum?

Asked by: litnana
Well, technically, Cils Booster is NOT a serum. It actually IS a conditioner though. You can apply it as a masque at night on your lashes and brows. Make sure you have cleansed your face, apply to lashes and brows, and go to bed. Upon waking, you want to rinse with warm water, run a little toner over the face and use the rest of your face regimen.

Is it good for a lash conditioner when used alone?

I would like a product to use as a lash conditioner on days when I do not wear mascara...
Asked by: MonetteN
Cils Booster is a great product for the lashes. It is vitamin infused and makes a great conditioner for the lashes, as well as the eyebrows. When used prior to mascara, it gives you more depth of color due to the white coloring of the product. It creates a great base that allows your mascara to get that little "oomph" that the lashes need. However, it makes a great masque for the eyebrows and lashes at night. All you have to do is apply to clean lashes and brows before you go to bed. That's it! And with the new look, it also has more ceramides as well!
