For crazy long lashes, follow with a coat of Lancôme's HYPNÔSE DRAMA

Birchbox Breakdown

Think of this lash primer as your mascara’s essential sidekick, working behind the scenes to make everything perfect. It plumps and lengthens lashes, creating a base that seriously amplifies your mascara’s impact. If you’re going for beautifully defined eyes, you’d best work it into your routine.

How it Works

Micro fibers add thickness and length to lashes, helping even the shortest ones stand out, while Vitamin E nourishes and protects. The formula ensures that mascara evenly coats lashes, and enhances your mascara’s pigment.

How to Use

Apply one coat of Cils Booster XL to lashes. Allow to dry for 30 seconds, then apply your mascara of choice.

Long Long Lashes

I wish I would have found this years ago. It makes my short lashes look amazing when paired with Lancome mascara.

Just dreamy!

I absolutely love Lancome CILS. I use it before my regular routine of curling my eyelashes & adding Lancome Definicils mascara. This product truly intensifies my typical mascara results! A must have for the lover of thick, lush lashes.

HIgh Quality Lash Primer

This lash primer will boost the performance of your favorite mascara. I've been using it for years, both with Lancome mascaras and other brands' mascaras. It gives my lashes some extra volume and length, helps my mascara stay on longer, and prevents smudging and flaking. Once you start using lash primer you'll never go back to mascara alone!

TIP: Let the primer dry on your lashes for a minute before applying your mascara. This way the fibers have a chance to bond to your lashes and add length.
