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 wish I wasn't this extra, but this stuff is AMAZING!! Instant volume!
A must have!
Luv2sparkle from California
I would have never thought a mascara primer would be that important, but this one makes any mascara better. I have a few I like: Thrive mascara and any thing from Tarte. This plus mascara gives me back the wide eyed look I had in my twenties. Yes, I still want it. It makes my mascara a little harder to wash off, but that is also a plus. It keeps mascara in place. That will be even more important when the weather is warmer. I will keep buying this product and a travel size for on the road. It lasts a lot longer than mascara even though they say 2-3 months.
AJ from TX
I hardly wear makeup & I had the ugliest little eyelashes like no curl, no volume, no length. I got a travel size primer for christmas and DUDE!!! Keep in mind i've always started using grande lash and grande lash repair, but this primer gives my lashes curl even when I take off my mascara! Pair this with bad gal bang mascara & thank me later! If you haven't tried this primer then you need to. I'm not like a splurge on eyelash primer, i don't got it like that but when I run out of my travel one, I will be picking up the full size of this bad boy!
An absolute MUST in my makeup bag!
Tori from Chicago, IL
I honestly never thought mascara primer was that big of a deal and thought it was just a waste of money, but thanks to some sort of special on this, I decided to try it. I absolutely love it! I'm not a mascara person in general because I feel like it doesn't make much of a difference in my lashes, but with this primer, I feel like I'm wearing falsies! This will always be stocked in my makeup bag from now on. I love it!
The Best One I've Tried..
Shey from New Jersey
This product definitely helps boosts lashes by adding subtle length & thickness. I noticed it works better with Lancôme mascaras (especially Monsieur Big Mascara). Worth buying again for sure!!!
Pmo from Iowa
I had big expectations but was left very unimpressive! Save your money!
Tried and True Classic
Jen from Oregon
I've tried several other lash primers and they simply do not compare. This applies easily, thickens, and lengthens. It works under any mascara and holds all day. It lasts about 3 months of every day use, so definitely worth the money.
Best eyelash primer on the market
Carli B from Des Moines, IA
I've been using this for a week now. It does not make my lashes look clumpy at all. It lengthens and separates beautifully! I have tiny short eyelashes and this does wonders for my lashes. I have not worn fake eyelashes since I started using this
Best product ever, a must have.
Liz from Illinois
Every time I would wear mascara, no master which one, would give me dark raccoon eyes by the end of the day.
This product makes that not happen.
And keeps lashes perfect all day.
A must have, totally worth the price!
The best stuff.
Rach395 from Tennessee
I did not believe this stuff was going to make that big of a difference with my eyelashes but I was very wrong. It makes my eyelashes so long and full. I highly recommend.
Best lash primer!
Ally from Las Vegas
I don't wear a lot of makeup but mascara is definitely a must. This primer makes your lashes full of volume and conditioned. I love wearing this at night for that added conditioning.
Where has this been my whole life?
Megan from Patterson
Why aren't more people talking about this? Literally goes toe to toe with my false lashes. I will never be with out eye lash primer again.
Meg from Georgia
First off, I am sooooooo picky about my mascara. I've been using Benefit Bad Gal Bang mascara and love how long and clean my lashes are with it, but I didn't feel it was going on thick enough for any sort of volume. I've paired it with this primer and the results are just... WOW! Definitely don't need false lash extensions! Will buy again, it's amazing!
Great lash primer!
Acat from VA
This is my first time using a lash primer. I like how it coats every lash with just a few strokes & doesn't clump up. when I apply my mascara (Nars Climax) it glides on smoothly & gives my lashes that extra volume I need. perfection!
The Product You Didn't Know You Needed
Marissa from Colorado
I don't do these reviews often, but this product deserved one. I have never used anything like it before. It's the best thing I have ever used . I pair it with the Lancôme Idole mascara and my lashes look full but not clumpy. I used to use the same mascara from benefit for years until I tried these products. It lengthens and prevents lashes from clumping. I use less mascara than I needed to before. Definitely by this
luv2run from Alta Loma, CA
I was using another primer for years and decided to try this. Used it three times and had itchy and burning eyes. Went back to my other primer.
Hannah from Washington DC
Such a great primer!!! Works so well I'm very pleased with the product.
Definitely Great But Doesn't Stay Up
Jennifer Le from Philadelphia
If you usually buy waterproof mascara to keep you lashes up, this primer is not it. They did give me longer lashes but I wished they kept up :(
Lala from Illinois
I received a sample of this with a full size mascara I purchased. I've never used this before and now I'm hooked. Between this and the mascara, my lashes look so much better when I slap on some makeup. I put this on then the mascara while it's still wet. Great product!
Lacy from Tn
This stuff is awesome! Makes a huge difference in my mascara!!!! I'm on my third bottle !
Liz from Kentucky
Technique is key with this product but I do love this lash primer it lengthens and separates the lashes wonderfully. However, I really wish they would redo the packaging. I wish the opening was smaller to remove excess product off the brush before you apply, it has a tendency to get very clumpy.
Megan from Texas
What I love most about this primer is it separates and lengthens the lashes in preparation for mascara. Sometimes when I go straight to mascara it ends up clumpy from previous mascara residue but this primer ensures each lash is separated and long. Such a great prep item and can make even your cheap mascara go on nicely
April from El Paso, Texas
I have tried mascara primers before and some have been messy and do not work. This one is amazing. It doesn't make a mess at all, applying it is very quick and it adds great length to my lashes. Perfect if I want to elevate my look without putting on fake lashes.
worth the $$$$
Andrea e from Miami FL
by far my favorite . I love it. wish it wasn't so expensive
Elisabeth from Michigan
This will make your lashes amazing! I like the more natural look and don't do a ton of makeup and this really helps to make my lashes pop! I also find that it also helps make it easier to remove my mascara at night. It goes on white and dries clear. No flakes. No tarantula legs (LOL). I use it with Urban Decay Perversion mascara. See my before and after photo!
