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.
Reviewed by 2149 customers The only mascara primer I would ever buy
ginzy from New Jersey
use before Lancome mascara - since eyelashes very thin, become thicker
No more black circles from melted mascara
No more black eyes! from Jeff City Missouri
I hate at the end of the day when you look and half your mascara is under your eyes making you look like you have black eyes. If you use this primer first you can by cheap mascara to go over it and it will stay on and not smear. While the price is a turn off saving $ on expensive mascara makes up for it. Also makes my lashes look longer, like putting conditioner on them each day!
Cher from Phoenix
Separates lashes and makes them much longer. I heard the Essence Lash Primer was a dupe for this. I tried it because of the price point. NOT EVEN CLOSE! This primer is the best. For those who have issues with it being crunchy, don't let the primer dry before you start to apply the mascara.
Good product but needs better design
SK from Michigan
I like this product and I have seen results of thicker longer lashes but too much product comes out on the brush! I have to scrape a lot of product off before I can brush on my lashes. Also, do not wait til they dry to coat with regular mascara.
KS from TN
I have tried everything out there and this by far is my favorite!! It doesn't get dry or clump and my lashes have tons of volume & separation!
Works well, doesn't last very long
Jess from AZ
This product works well! I can definitely see a difference in my lash volume, however I feel the product it self does not last long for the price. The lid gets caked with primer, so after screwing it on-off so many times, it won't screw shut all the way. I would buy again, just needs a better container.
My thin straight lashes now have curl and length!!
Jessican from Wisconsin
Amazing product! Have been using this product for years. My lashes are hardly existent because they are so short and thin. Stick straight too. Using this product everyday under my mascara has made my lashes longer and curly! I've never had more beautiful lashes! I get comments all the time about my lashes now!
Kimmies from Boston
I have teeny lashes and this helps. Always keep an extra in stock. Doesn't irritate like some lash extension formulations do
Go little rockstarrrr
Ambxox from My room
I really like this! Makes a difference for sure! I will now never not use this before applying mascara!
you need it
Molly from TN
If you love mascara and trying new stuff, you have to try this! I went back and got more as presents on black Friday. It's going in all the stockings!
I love it!
Marie from Iowa
This primer gives great volume and length to my lashes! I comb through my lashes after applying so I don't have any clumping and then wait at least 30 seconds before applying my mascara. I don't see any white afterwards. I'm in love!
Alyssa from Salt Lake City, Utah
Never tried a primer before and best way to start! Has made my eyelashes a lot longer!!
Loved how it gave My long thin lashes definition.
Cla from Woodbury, mn
Use it daily. It works great with my highly sensitive eyes.no reaction at all!
Definitely Look Up How To Use
Carly from VA
Bought this when it was on sale. used it a couple times and hated it. made my lashes hard and not pretty. thought I would look up to see if I was using it correctly and I definitely wasn't! make sure to put mascara on while the product is still wet! love it now!
SoSad from Texas
I'm guessing this only works if you have nice, curled lashes to begin with. I curled my lashes, applied this, then followed with a Lancôme mascara. My curl fell before I could even put the mascara on. It made my lashes look ugly as well. My mascara looks and does so much better without this primer. I'm sad cause I had high hopes for it. I had been wanting to try it out and got it cause it was on sale. So disappointing. I never leave reviews, but this primer was disappointingly I just had to. If your lashes aren't perfect already, don't waste your money. Zero stars… don't recommend
burning and watering
amanda1nc from Stokesdale NC
I love Lancome mascara. i received this in a set with my favorite Hypnose Non waterproof mascara. this lash primer made my eyes burn and water like crazy almost immediately. I've never had a problem with any of the Lsncome mascaras however this product is on my 'do not use' list!
love this product

makes my lashes real thick, I am glad I found this.
if you have straight eyelashes, don't waste your money

Thick, clumpy, not a good look
Eli B from Cortland, NY
I bought this to act as a primer but it's too clumpy. Even when I wiped some product off, it clumped my long lashes together. There is a $5 white primer that costs MUCH less and works much better.
Best lash primer out there
Ella from The South
I love this primer for my short lashes. Using it with a volumizing or lengthening mascara gives an unbelievable length and fullness to even my stubby lashes.
Caused uncontrolled eye twitching
Jordan from Texas
To start off I love Lancôme products and have used them for a while. However this was the first time I had a reaction *if that's what you'd call it* to one of their products. The first time I used it was for a week back in March. I loved the product at first but then I noticed my eye lids started to twitch / reflex. I stopped using it and after a week or so my eyelids stopped twitching. So I tried again this week *it's November* and after a few uses my eyelids are twitching again! I don't know what is in this product that would cause this but it is scary and concerning to me as I use other products from this brand everyday.
If you wear mascara, you need to use this!
Review from Massachusetts
I've been using this product for almost 7 years now. Hands down the best lash primer. I've tried Dior and chanel lash primers and they don't even come close. This is so incredibly beneficial for the lashes as well. I've noticed a huge difference in my lashes since I started using this product and that's why I've continued to for all these years. Don't wait!
Does nothing-Must be paid reviews
ali from ca
It does nothing for lashes. I tried it with a lancome mascara and its actually better without the primer. These reviews must be from paid.
beava from WI
I have tried several primers before. probably spent hundreds of dollars for a cheaper version and nothing compares to this! I love that it isnt clumpy and goes on like butter! It also doesn't dry out fast!!
Jennifer from Memphis
This is the beat lash primer I've tried to add depth to night out lashes.
