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 2163 customers My favorite lash primer
Janeane from Pocatello
My lashes look great every time I use this primer. Keeps lashes curled and gives volume even with wet or heavy mascaras.
The Queen of Mean from Omaha, Nebraska
I use this every single day. It fans, fluffs, separates, thickens, and lengthens my lashes. I'm 60, so my natural lashes aren't what they once were, but this product combined with my mascara makes my lashes look like they did when I was in my 20's.
I keep this product at all times
Sarah from Virginia
I have been a lifelong lover of beautiful fluffy lashes, and I wish this product had been around all those years. I use it every day before applying my mascara. It keeps my lashes soft and hydrated, and defines them for the smooth and even application of mascara. I use a mascara that is not harmful to my lashes, but I am extra confident I am doing them a favor by having this primer as a base coat to protect and support lash health. Since discovering this product, I will not be without it!
Best Primer Ever!
Nurse777 from Louisiana
My lashes were a mile long after using this paired with my Thrive mascara. Love it!!
The best eyelash primer!
Summer kinda gal from San Diego, CA
This is the best eyelash primer I have ever purchased! I love the volume and length it gives my lashes. I will definitely buy this product again.
Not anything special
Sam from Illinois
I bought this on sale because it had amazing reviews. I personally don't think it's that great…. The 5$ essence brand primer I think is better than this one.
MeganB from Ohio
Well worth it. It separates my lashes and extends them perfectly for my mascara. Applying my mascara is so much easier and coats more evenly after using this. I love it I feel like it also makes my lashes look thicker
Best, I use this daily
MooreA from Murfreesboro TN
Excellent thickener and eyelash separation. Love this product!
Save your money
Bethany from Chester springs PA
What am I missing??? I bought this because of all the amazing reviews. It did nothing for my eyelashes. It irritated my eyes so bad and made my eyes burn.
Later I developed a bunch of white bumps on my lash line.
I have never had a problem with primer. I will go back to my L'Oréal primer.
Made no difference
Jan from Houston
I was sold this product because I have problems with flaking mascara & raccoon eyes. It did make my mascara appear thicker, but really just made it look clumpy. I used it on both eyes the first day. The next day I only put it on one eye as a test . There was more flaking & raccoon eye on the side with this product than the eye with just mascara. I will be returning it.
BUY IT! Game changer
Daya from Cali
Use the primer and apply your mascara while it's still wet, and one at a time is easier! I never thought an eyelash primer was even necessary, but this primer made my lashes become thicker, longer, but still separated!! It made my mascara last at lot longer too, it kept it on all day. Honestly, if you're thinking about buying it, spoil yourself and do it.
This is the bomb diggity.
TresaD from Fairbanks, Alaska
I love how much length you get by using this product. Its a great product.
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!
