  • Great lash conditioner
Size: 0.19 Fl Oz (Pack of 1)
Lancôme Cild Booster XL is a great addition to my eye makeup routine. It conditions my lashes and keeps my mascara on longer. It also has helped with lash growth.

  • A must-have step for perfect lashes! A must-have step for perfect lashes!
Size: 0.13 Fl Oz (Pack of 1)
I’ve been using this Lancôme lash primer for about a year now, and it has completely changed how my mascara looks. It does an amazing job at separating and defining my lashes before applying mascara, which helps prevent clumping and makes my lashes look longer and fuller. It goes on smoothly, dries quickly, and really helps my mascara last throughout the day. Even after consistent use, it hasn’t caused any irritation and has become a staple in my makeup routine. ✅ Pros: • Separates and defines lashes beautifully • Prevents clumping and enhances mascara performance • Long-lasting results • Gentle on lashes and eyes ⚠️ Cons: • A little pricier than drugstore primers, but worth it for the quality Very pleased with this product—highly recommend if you want to take your lash game up a notch! ... show more

  • Friend Group Fave
Size: 0.19 Fl Oz (Pack of 1)
I got this in a giveaway from a creator I follow and have never stopped buying it since, and now all my friends buy it. I probably have at least five people on it! Totally worth the money! Makes your lashes longer, healthier, but also the white does not show through your mascara like other primers. I also think it lasts really long time and helps my mascara from flaking. ... show more

  • Great Primer Great Primer
Size: 0.13 Fl Oz (Pack of 1)
I love this primer. It's a bit expensive but I don't wear makeup every day so it was fine for me to get a small size and it has lasted awhile without drying up. It works with any mascara, is easy to cover the white and adds length and volume to my lashes. 4 stars because it is a bit pricey, but it is worth the price rather than a cheap clumpy primer. I have used primer for 2 decades and this is the best one so far. It's been about 3 mos and no signs of clumps or of drying up. ... show more

  • Totally recommended: A Lash-Lifting Miracle
Size: 0.19 Fl Oz (Pack of 1)
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

  • Lash Explosion, Worth Your Money 100X Yes!!
Size: 0.19 Fl Oz (Pack of 1)
Absolutely love this mascara primer! The application is easy and smooth. No clumps, just healthier, longer, fuller lashes, that look amazing with little work!! I love that the primer color is white. This makes it soo... easy to see that the primer is actually on all of my lashes and then easy to see when I have covered the primer well with my mascara. One important tip to know, is that you must place your mascara on immediately after you stroke on your primer... you do NOT wait till it dries! I have used this for a long time and been extremely happy with the results. It is on the expensive side, but I feel it is definitely worth the money!!! Absolutely!! ... show more
