Most Helpful Positive Review CILS Lash Booster
First let me say this product doesn't "promise" anything and just like all cosmetics it's success depends on the user's personal reaction. I personally like this product alot. I'm 3/4's of the way through my 50th year and have been a Lancome devotee since my 20's. Yes, some products I don't use because the results were not what I was looking/hoping for and some I will always use. CILS Booster is one of those products I'll always use. I can't, in all honesty, say that my lashes are "thicker & longer" but I can say that my Definicils goes on more evenly, my eyelashes are healthier & don't seem to fall out as much and I just like the "look" my eyelashes have when I use it. It's all a personal preference and I prefer to use CILS Booster :)
Most Helpful Critical Review Makes your lashes crunchy
This accidentally came with my order so I didn't purchase this product. I didn't like this at all. I hate any mascara or primer that make my lashes hard and crunchy. This did just that. It does make my lashes look bigger but it also clumps then together. After it dries it makes my lashes feel like tiny needles poking out of my face. Nope not for me. I only recommend this if you don't mind that crunchy lash feeling because it does work. Also, I didn't use this with a Lancome mascara. I used a Dior one. Maybe it would be better paired with a Lancome product? Since I don't intend on stitching mascaras this was not for me.

I didn't have that much faith when I saw it and thought it was going to be one of those expensive products that dont work BUT THIS THING IS THE MOST AMAZING THING EVER. I always wear fake eyelashes and I stopped two weeks ago and mascara is always so eh, but with THIS it makes them so long and beautiful I love it with all my heart

I love this!

I use as my primer before mascara.
Ashley K. from San Diego, CA
The only makeup i wear is chapstick and mascara so even though it hurts to pay so much i justify it because it's one of the few products i use. I use it to prime and separate my eyelashes before using my favorite mascara (toofaced-better than sex!). I have also used it under other mascaras and it's still worked beautifully. Keeps mascara on all day, no flakes. Can't wear mascara without it!
You won't find a better primer!
Vannah from MO
I have tried all the primers on the market! Some I really liked, but none compare to this primer! I have been using it for at least two years. I will say that I had not been using it as much due to the pandemic and no need for makeup, but I recently started applying it without mascara just to keep it on my lashes, because they were very obviously missing the benefits of this product! Since using again, my eyelashes are back to fabulous! I can't tell you how many people have asked me where I go to get my lashes applied, and I LOVE to see their faces when I share that it's Cils and these lashes are all mine!! Buy it! You'll love it!
BEST PRIMER !!
Lily from San Francisco
Best primer for lashes !! I do two light layers and wait a couple seconds before applying mascara. Works great!
Holy Grail, really.
dahliadollface from Virginia Beach, VA
I got this as a sample with an order a while back and used it just because I had it. It definitely made my mascara look the best it's ever looked so I kept using it. The little sample tube has lasted quite awhile but I liked it enough to buy a full size for when that one runs out. Today as I was getting ready before putting the primer on I looked at my lashes, (which were extremely short with no curl whatsoever) and actually noticed a real change! I actually have lashes that are now long enough to do what lashes are supposed to do and protect my eyes. There is also a curl to the lashes on the ends which I have never had. I didn't go into using this thinking it would do anything for lengthening or growing my lashes, I just was happy to find something that enhanced my mascara and worked for someone with lashes as short as mine but now over a month later I see that there has been a real measurable change. Hello holy grail status!

It seems to condition and strengthen my lashes and helps my mascara go on easy..
DID I LOVE IT.
Maggie from Cleveland Ohio
Of course, I did! Do I want to give away my secret? No! But, honestly, this stuff is magic! I mean, Tada! You got lashes! Try it, you will never go without it!
Great eyelash primer!
Rachel from VA
I absolutely love this! I did a side by side comparison when I first got this and they eyelashes that I applied this to before applying my mascara looked thicker, longer and separated better. My mascara also stayed on well throughout the day. Very impressed. It is expensive, but if I am using a primer for everything else (face, eyes), it makes sense to do this on fragile eyelashes that get coated with mascara everyday that are also supposed to protect our eyes.
So far so good
Danielle from Los Angeles
I like it so far I feel like my mascara lasts longer. I don't know if I would buy it again since it's a bit pricey but if it lasts me a while then I probably will.

I use it before I put mascara on. It builds a nice base and my lashes look thicker.
JR from Gainesville, Georgia
Easy to apply and adds volume and length to your lashes.
CABPATTON from USA

Best lash conditioner !

expensive and does nothing
Annie from New York
This made my lashes flat and point straight down- even w a curler and Lancome mascara!!!
Best way to wear any mascara
GagaV from Pennsylvania
I will not put on mascara without using this as a primer first. The reason? It definitely helps with the "wow" factor for eyelashes and I've noticed that it helps keep my mascara from smudging/running in whatever weather, whether it's the heat of Arizona, working out in a gym, or the heat/humidity of Pennsylvania.
the BEST mascara primer
Michelleof2 from Holly, MI
i've tried other brands and keep coming back to lancome! the cils boost makes a difference and is a MUST for anyone who wears mascara!
Lulu from Richland Wa
This is a great lash primer!
This is a staple of mine!
Kim from Pa
Put it on as a base before mascara. Dont let it sit too long before applying the mascara.
Lori from Rochester NY
Not worth the money. There's nothing great about this product. I've used drug store brands that are better. very disappointed.
Creates the illusion of fullness with a buffer
Natalia from Indiana
The full size Cils Booster is actually 0.19 oz, not 0.14 oz. It is a phenomenal product that takes my scrawny lashes to the next level. It also creates a buffer between my drugstore (and prestige, waterproof) mascaras to lessen the damage at the end of the day. It facilitates mascara removal.
Found a winner!!
Jen from UT
I was hesitant to spend the money to buy this but am so glad I did.
I didn't want fake lashes, lash extensions, etc. There had to be a better way.
This is absolutely it!!
Best way I have found to use it is waiting about 30 seconds after applying to put on the mascara. I use Buxom's "They're Real" with it and the duo is a winner for sure!!
so worth it
Melissa from PA
I notice a huge difference when using this primer. My lashes look so much longer and my one nice mascara that sometimes runs/smears stays on perfectly when I apply this primer first. I purchased expensive lash growth serum in the past, but I'm done with that and don't even think it's necessary when using this primer!
