I got this as a 100 point perk from Sephora and I love it so much! It works so well; I definitely notice a difference when I use it. It elongates and separates lashes beautifully. It makes mascara go on better and faster. I will for sure be buying this in the future!

Although this a bit on the pricey end, this works amazingly well. Using this will make my mascara go on smoother, and my lashes will look better, better curled and more volumized.

I never ever put my mascara on without first putting lancomes cils booster before. I curl my lashes, then put a good coat of this one both upper and lower lashes, wait to let this dry, and no matter what mascara I use over it it makes a HUGE DRAMATIC difference! Spend the money you won't be disappointed! I've been using this product for 17 years and haven't been without it since the first time I tried it....it's that awesome! I also regularly get compliments on my lashes!

expensive but you get what you pay for! I have had countless samples of this and repurchased a couple times. It is so amazing and makes any mascara seem like high end! makes it easier to take off mascara too because there isn't as many layers of black to remove (as you only need a bit of mascara over this to make super thick and long lashes! love love love See my full review on youtube at this link: https://youtu.be/1Vbhqs5txi8

This is an awesome product! I got a trial size of this product from one of their bonuses. I got a Lancome mascara as well and I absolutely hated it. But this base seems to make every mascara work beautifully. I like to do one eye at a time, and that way it looks more realistic. All it does is separate the lashes and add a bit more length. If you want a more glamorous look, let it dry a little before applying your mascara. Price is a bit steep for something that really is unnecessary, but I would honestly probably buy it once my trial runs dry... it really does make a difference.

Great base for longer and fuller eyelashes. Apply this one before your regular mascara, results will be amazing. Im always looking for volume and this is a great solution without applying countless layers of mascara. Like it a lot.

love it. I have very small eye lashes and there has never really been anything that helped especially with the bottom lashes. Lancome Cils Booster works amazing. You just need to add before your mascara and you have amazing thick lashes.

Cant live without this one! Makes any mascara work better for you! This Lancôme product will take your usual look a notch higher. It adds glamour to your lashes. I also find it makes my mascara tear proof , not quite water proof but a few tears won't budge it!

I absolutely strongly recommend the Lancome Cils Booster XL for everyday use with your favorite mascara. I prefer to use this lash primer with my favorite Lancome Definicils mascara but it will work with any other mascara and give it the length and volume look that will amaze you. I cannot go without this lash primer. Wish it wasn't so pricey and wish the packaging was a bit more sturdy because after multiple uses the cap did crack but it did not damage my lash primer. LOVE LOVE this stuff.

This stuff really works. After applying it and my mascara I looked like I had false lashes on. Amazing. Obviously you have to have time for this extra step but is great for a night out or special occasion.
