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!

Love LancomeCils booster for my eyelashes. I am 69 and have very fine short lashes but when I use the Cils it actually extends my lashes so they are very noticeable. I also use Definicils as my mascara.

I wear this with the Lancôme Définicils High Definition mascara, and together (at least for me) they are perfect. Together, they make my lashes full and soft. Use a light hand and it won't clump. It holds the mascara and the curl all day. Bonus: if you are a traveler, both this and the Lancôme mascara take up less real estate in a make-up bag than one tube of most drug store brands.

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.

yo let me put y’all on this lancome cils booster xl primer real quick bc it’s actually insane?? 😭 okay first of all, this is giving MAIN CHARACTER ENERGY for your lashes. like i’m talking 2016 ig baddie lashes without the $150 extensions. the formula has micro-fibers and vitamin b5 so it literally builds length and volume BEFORE you even touch mascara?? i’m lazy af and this does the heavy lifting for me. texture: 11/10. it’s white (yes white, don’t panic) but dries down clear and doesn’t flake. separates every single lash and makes them look fake even when i just use it solo on no-makeup days. then when i layer my regular mascara (currently using the maybelline sky high bc duh) it’s straight up giving fibre lash extensions from 2014 but better?? no clumping, no spider legs, just fluffy long ass lashes that touch my brows. staying power: survived me crying during a tiktok about golden retrievers, a 3-hour hot yoga class, and my situationship texting “wyd” at 2am. waterproof who?? we don’t know her. price hurts a little (like $30… miss lancome why) but one tube lasts FOREVER and sephora always has sales + i use my ulta points like a broke girl hack. final vibe check:
✨ length: 12/10
✨ volume: 10/10
✨ no fallout: yes
✨ worth being broke for: absolutely if you have short stubby lashes like me (iykyk) this will change your life. period. go run don’t walk, i fear i’ll never shut up about this 😩🤍

The media could not be loaded. 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!!
