If you’re wondering whether you can get more ‘oomph’ out of your lashes and mascara without having to glue on falsies, a lash primer just might be what you’re looking for. The best primers have lash-plumping microfibers to give the appearance of thicker and longer lashes. Lancôme’s Cils Booster XL Enhancing Lash & Mascara Primer is a serum for your lashes and not only includes microfibers but also conditions your lashes, leaving them feeling soft and looking defined. Right now, this luxe primer is 30% off on Amazon. Here’s why it could be your new secret to longer and more lush lashes.

The Lancôme Cils Booster XL primer stands out in the beauty world for its ultra-conditioning formula that contains vitamins E and B5. Mascara, particularly waterproof kinds, can be somewhat drying to your lashes, and a good primer can help prevent them from becoming parched. The 2-in-1 primer gives your lashes a coat of conditioning, creating a smooth canvas for mascara. You can also use it on its own at night to nourish and condition lashes.

Tiny microfibers in the formula add to your lashes, giving them more length, volume and curl. Just swipe it from root to tip like you would a regular mascara. And if you plan to use it over mascara, make sure the serum is still damp and doesn’t dry out before you finish doing your lashes. It’s great to use under Lancôme’s Lash Idôle Lash-Lifting & Volumizing Mascara (currently 25% off!), as the two work together to plump up even the shortest and thinnest lashes.

Customers rave about this primer. One even says, “It makes a difference!! I’m really fussy about my eyelashes and have never tried a primer before. I was amazed at the difference this made in my lashes after applying mascara.” Another customer says, “I love this product! I had a co-worker ask me if I got lash extensions, and nope, I didn’t. I used this product as a primer then put mascara over it! It makes my lashes fuller and longer! I highly recommend it!”

Lancôme’s luxe primer just might make you question whether getting lash extensions is really worth it. The smooth and creamy formula is easily brushed onto your lashes, giving your mascara a huge boost. Hurry and add it to your cart while it’s still 30% off.
