  • Amazing!
Size: Full Size
For years I would use waterproof mascara and found I’d have smudgy black marks under my eyes a couple hours later. I have oily skin so I just figured that’s what was causing the black smudges to happen more quickly. Then I learned of Cils booster, applied before mascara … total game changer! Not only does it help create a lengthening lash line, it is the perfect primer for any type of mascara (I can use regular mascara now!!!). Who needs falsies when you can plump and lengthen using Cils and a good mascara (Lancôme has the best!). Plus, eye makeup removal before bed is quick and easy since I’m not dealing with waterproof mascara anymore. You need this!!! ... show more

  • Totally recommended: A Lash-Lifting Miracle
Size: Full Size
I've been using the Lancôme Cils Booster XL Enhancing Lash & Mascara Primer for quite some time now, and it's become an absolute must-have in my makeup routine. This primer has completely transformed the appearance of my lashes, giving them a longer, thicker, and more voluminous look. The key to using this product effectively is to apply mascara immediately after applying the primer. This ensures that the mascara adheres to the primer, creating a more dramatic effect. I've paired this primer with various mascaras, and it complements them all beautifully. It seems to intensify the color and volume of any mascara I use, resulting in a truly stunning lash look. One of the things I love most about this primer is how natural it looks. It doesn't clump or flake, and it doesn't feel heavy on my lashes. My lashes appear longer and thicker, but not in a fake or unnatural way. It's a subtle enhancement that makes a big difference. Removing this primer is a breeze. It washes off easily with micellar water, leaving no white residue behind. I've never had any irritation or sensitivity issues with this product, even though I have sensitive eyes. I believe it's absolutely worth the investment. The results are truly remarkable, and it lasts for a long time. If you're looking to take your lashes to the next level, I highly recommend giving this primer a try. ... show more

The mascara, lash curler & lash primer went excellent. I will be using it again!

  • I see a difference
Size: 0.13 Fl Oz (Pack of 1)
When I wear this vs when I don't. I definitely like the idea of giving my lashes a little boost/hydration and used to use the mascaras that had the two in one booster/mascara. Since I started to limit toxins and started to use clean brands, I haven't seen any dual ones, so this one is the one I prefer. ... show more

  • It Works
Size: 0.13 Fl Oz (Pack of 1)
I rarely wear fake lashes so not good putting them on. This actually works & makes the mascara to follow seem about 50% fuller & longer. Disappointed I waited so long to buy. You only need two quick strokes to get the 50% thicker/longer lashes, in my experience.

  • I like it

I wish I took before and after pics. I do notice my eyelashes look longer after immediate uses but I also think there is something in its ingredients that make your eyelashes stand up to look noticeably longer but it also does make them stronger too because I lose less lashes when taking off my eyelash glue ... show more
