    • Best eyelash primer ever
Size: 0.13 Count (Pack of 1)
Conditions your lashes while it adds volume and length to your lashes. Apply mascara seconds after primer dries and you can see what a difference it makes between not using the primer and using it. There’s NO CLUMPING and mascara lasts 2-3x longer.

    • A must-have step for perfect lashes!
Size: 0.13 Count (Pack of 1)
Review Image by The Magic Haul
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

    • Best primer ever!
Size: 0.17 Count (Pack of 1)
The best primer ever! Worth the cost! It makes mascara last longer and it’s not clumpy, I tried it once and it’s my go to. I’ll gladly splurge on it since it works. I have tried the Maybelline L’Oreal and even an offbrand on Amazon and nothing compares.

    • Not the holy grail BUT very good still :)
Size: 0.13 Count (Pack of 1)
Review Image by Lindsay
It’s good! I’m still on the hunt for the *perfect* primer, but this works quite well for me in the meantime :) The product is quite thin for a primer, which is good imo, because primers tend to dry out on me so fast 🙄 I’m hopeful that this one will last longer! It’s also good because it won’t clump so much. This one doesn’t clump at ALL 🙌🏽 That said, this isn’t the most volumizing primer I’ve ever used. It’s definitely lengthening, but not so much volumizing. I tested it out today, as you can see in the photo. I first tried only one coat on the left eye shown. I wasn’t very impressed with that one. So i took everything off my left eye and redid it with 3 coats of the primer. And that time i got much closer to the results i was looking for :) And for anyone wondering, the best volumizing primer I’ve found thus far is the urban decay subversion primer (i also use their mascara—perversion—which is what I’m wearing in the photo). I used that one for a long, long time! But, as i mentioned before, it dries out so fast (and at that price point? Ugh 😭), AND it tends to clump your lashes together so you have to be really careful about separating them (i used a mechanical pencil lmao). I haven’t decided whether to get that one again. Just trying this one out for a while! That’s why i got the travel size :) ... show more

I absolutely love this! I curl my lashes first, apply this and let it dry, then finish with my mascara. It honestly makes my lashes look like I have lash extensions! My only regret is not buying it sooner. Highly recommend! (This picture does no justice to how it truly looks in person)

    • Lancome lash booster

I love this lash booster! It will lengthen and thicken your lashes. My best friend and I have been using this for years. We both love it! It goes on white then you apply mascara on top. The price isn't too bad at under $20 a tube.
