I received this as a sample size as a free gift with purchase. I absolutely love it! My lashes are average but this helped create long beautiful lashes that stayed on all day. Will definitely purchase.

this is amazing product!!! I can't rave more than enough. Before I never used a primer, and didnt really see the need for it. But I got it in the Lancome GWP last year, and once I used it, I fell in love with it! Instantly, I can see the difference to my eyes. The lashes were extended dramatically with the white little fibers. After, just apply any mascara and you're good to go! This is the product that really made a difference to my eyes. Before, my lashes didnt look curled (drooped down during day even with curler), and lashes were actually noticable. (I have a hidden double eyelid). This is a product i cant live without.

I've used about 3 tubes of Lancome Cils Booster XL because it helps create very dramatic eyelashes and keeps my mascara from smudging. It lengthens so well and helps seperate lashes so they don't get clumpy when I apply my mascara. With some volumizing mascaras, I find that the mascara base can sometimes lessen the thickening effect and I only get the lengthening properties-- so that is something to watch out for. I will continue to repurchase Cils Booster XL because it helps my mascara last all day!
