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 don't even know where to begin. I've been using this for about 2 to 3 years now. Every time I try to go to some thing else that may be is a little less expensive, I am so disappointed and I just keep going back to the real thing. When are use this product my lashes are full, separated, long, the best ever. I had cancer and lost all my hair including my eyelashes. When they started to come back, I began to use this. The best ever! I also tried to use other brands i.e. Urban Decay subversion, L'Oreal voluminous, so many different kinds that I don't even remember the names now. Nothing compares. Worth the price, worth the hype, worth 5+ stars.
Absolutely incredible. Nothing compares
Lancome Lash Lover from Phoenix, AZ
This is phenomenal. I get compliments on my lashed every single time I wear this underneath my mascara. I coat my lashes in this baby and let it dry. Then I top with mascara. This is the key ingredient in bomb lashes- no matter what mascara I use.
Beautiful long lashes
Alexandra from Az
At first I would use it after it had already dried but I realized that I've been using it wrong apply your mascara when the primer is STILL WET and you will get really beautiful long lashes!!!!
Just buy it
Bee from Pennsylvania
I have been using this for a few years & have tried multiple other brands & nothing even remotely comes close to this. Part of my daily makeup routine. It absolutely makes a difference under any mascara, it prevents clumping & makes my lashes look full & long. People think I wear fake lashes. My lashes weren't bad before I started using this but it definitely thickened my eyelash grow, I wish I could post a photo to show how thick & soft my lashes are. I use Makeup Forever "Excessive Lash" over this daily but I have used it under multiple other mascaras. It does not disappoint. Picked up during 21 days of beauty this time but I have/will pay full price because of how amazing it is. BUY IT!
Love this product
I give this a 8.5/10 from Amazing
I love this product it gives so much length and I have really short lashes it is such a game changer but it can get clumpy so be careful not to put too much
Chan from New Haven
I have never tried this product before, but when it went on sale for half the price I figured why not. This product is everything I was hoping for! It makes my lashes look super full, and the final result is amazing. I would give this a 10/10! This will be a permanent addition to my makeup routine.
Hannah from Seattle
So this is pretty good but nothing amazing. I notice a difference but it is a slight difference (did one eye with and one without). The trick is to apply your mascara immediately after using the primer. If you let the primer dry it's not going to look good at all. I got this during the 21 days of beauty sale but I would not pay full price. Not sure why everyone raves about it.
Mace from USA
I was fortunately blessed with long eyelashes. This stuff was insane, though. After application I just KNEW the outcome was going to be good. This formula will bring your lashes to the sky and it truly has zero clumps. In fact, it seemed to separate my lashes even with my mascara on. If you need a lash primer, definitely keep this as an option.
My favorite lash primer

It just doesn't do anything at all
Shorewood lawyer from Shorewood, WI
I tried this product based on the rave reviews and it just doesn't do anything at all. I've tried it every day for 2 weeks and followed the instructions, and Ive tried it with several different types of mascara (I recently received a bonus gift with purchase that included all sorts of awesome mini mascaras.) I started out using it with Lancôme mascara since I saw in the Q&A that it's designed to be used with Lancôme mascara- but I didn't see any difference after a few days. So then I tried it with mascaras from Tarte, Too Faced, Benefit, Grande, etc. Same lack of results. Finally, I thought maybe I just wasn't noticing the difference so I did a couple days where I only applied it to one eye. But even then, I saw no difference at all between the non-booster eye and the one on which I'd used the product.
I even got a sample tube of this with the previously mentioned mascara minis and tried that one, thinking maybe I'd gotten a bad batch or something in the full-size tube I ordered. Still nothing. No length or volume or curling.
Not sure why it's so highly rated, because I gave it all the chances in the world and it still did nothing at all.
Charlene from Chattanooga
This is the best lash serum I've ever had, it truly works!! You must follow directions in the "how to use" section. It made my super thin lashes look long and incredible!!
Best primer ever
AVH from North Phoenix
I have zero eyelashes since getting extensions. I love magnetic eyeliner ones but on occasion like to give my eyes a break. This stuff is amazing. I put it on and add Essense Princess mascara on top and it goes on smooth and instantly makes my lashes look longer. I love this stuff!!
Dee from Pittsburgh
Stocked up during the 21 days of beauty sale! This has been a staple in my makeup routine for a long while!
B.Mealer from Columbia TN
Absolutely amazing results for me!!! I use at least once a day if not twice I've seen a HUGE difference!!!
AD from Minnesota
The BEST primer ever!
It's a no from me dawg.
Aly from Pittsburgh
Either I'm not putting it on right, or the rest of the reviews are completely on another planet. I have ugly ugly ugly lashes after applying this stuff. I really wanted to like it. For the price I thought I would!
Md3 from Colton, California
This works extremely well.
sugardumplin86 from wisconsin
tarte brand eyelash primer is much much better. This one seemed dry & didn't put much product on my lashes. maybe mine was old? not sure, won't be buying again.
Pey from Chicago, IL
I purchased this a while ago and still am on the same tube. From my experience, it does not dry out quickly at all. It makes my lashes look amazing, and I noticed that after I started to use it, my lashes grew longer than they had been prior. I don't know if I'll ever stop using this product, it completely changed my makeup game. I learned that is personally works better when I let it dry a bit before applying my mascara. I have very full eyelashes naturally, but they aren't as long. So this product definitely lengthens my lashes without making them look clumpy like most mascaras do.
Ella from Plainfield IL
After the rave reviews, I couldn't wait to try it. It was a huge disappointment. I tried this on one eye and the L'Oreal primer on the other and L'Oreal blew this one out of the water on everything. First the brush on this is straight whereas the l'oreal one comes to a little bit of a point, which at first seems like no big deal but it's great to get those small corners and just applies the primer so much easier. The lashes looked fuller, plumper and longer with the loreal one. Take a look at the pictures when you scroll through them above advertising the product, I could barely tell the girl's lashes were longer and I felt the same while using this.
Works well but
Taylor from Fountian Valley
This products works very well and makes my eyelashes look amazing but it makes my eyelashes feel like they are about to fall out. Makes everything flakey and overall does not feel good
What are y'all thinking
OhioL from OH
Order this based on sooooo many recommendations. That was a big mistake, I have long fluffy lashes and this made them spider legs. Getting rid of ASAP.
Absolutely awful product!
Svetlana from Erie, PA
I ordered this after reading all of the rave reviews here. So, I don't know if these are generated by people who are paid to leave good reviews but this product does COMPLETELY the opposite of what it claims to do. First of all, this product made my lashes look super thin while clumping them together. It's actually quite amazing how quickly things went wrong. Imagine one of those Pinterest "nailed it" fail moments and that's what I experienced. I actually had to laugh at how bad it was.
Love this primer
Wshev from Reno
I love this lash primer. I feel like it really protects and nourishes my lashes. My mascara layers smoothly and this keeps it from smudging and flaking. It's a staple it my makeup routine
Anon from Sacramento
Love it, it really does thicken and help mascara go on beautifully and last all day!
