Editor's TipEditor's Tip

The secret to beautiful eyes is within reach. Follow these three easy steps: start with a couple of gentle squeezes with an eyelash curler, then follow with CILS BOOSTER XL to prime your lashes and maximize length, and end with a coat (or three) of lash lengthening Définicils mascara.

Birchbox Breakdown

You can always rely on the classics to deliver results, and Lancôme’s blockbuster Définicils High Definition mascara proves that rule. Its innovative brush shape separates and lengthens lashes while distributing an even, richly pigmented coating. A perennial best seller, it gives your lashes the high def treatment, delivering flawlessly defined and crazy long lashes, ensuring that, yes, you will be ready for your close-up (even in HD).

How it Works

The grooved bristles on the uniquely shaped brush provide gradual, even coverage on each and every lash, while special bio-selective polymers ensure that each lash is coated, root to tip. All without a single clump.

How to Use

Start at base of lashes and sweep the brush upwards. For heightened drama, apply a second (and even third) coat. Bonus: The mascara is fragrance-free and tested by ophthalmologists, making it perfect for sensitive eyes and contact lens wearers.

perfect mascara
Purchased

this is my go to and has been for quite some time. Love that it lengthens and doesn't clump. Great for day and to layer up going out at night.

A bestseller for a reason!

Definicils is a best seller for a reason. It really lengthens and doesn't clump. This isn't supposed to be a thickening mascara, so if that is the look you are going for, you may want to layer it with something else.

Best Mascara Ever!

Works great and never clumps. I've tried several and nothing works as well as Lancome. I would recommend this mascara.

Great daily mascara

This mascara is perfect for daily wear - lengthens lashes and provides a bit of volume without making lashes look clumpy!

No clumping

I haven't had any clumping with this mascara. It does not thicken as much as I prefer but it does make my lashes seem longer.

Best high end mascara out there!

There are only two mascaras I will use, and I've tried a lot of brands, this is one of them. Lancome Definicils High Definition mascara is amazing. I feel as though this lengthens and intensifies my lashes, NEVER clumps, and the packaging is sleek, bristles on wand are nice. Yeah it's a bit expensive but as a makeup junkie I keep on trying new brands and always go back to this (if you're looking for a good drugstore brand try Loreal Telescopic).

Nice

I love the color of this mascara, it is super dark. The only down side is that it doesn't thicken at all. Lengthens for sure. I use with another mascara that thickens and it's perfect.

Long, sweeping lashes

This marcara is a total win - gives you long, beautiful lashes without clumps and "tarantula eyes." The only thing I did notice is that it kind of has an odd smell? Not overpowering, but definitely not delicious.

BEST BY FAR!

I love, love, love the definition I get when using this eye mascara!! No better out there!

Fabulous lashes!

This mascara is both lengthening and defining, but not clumpy at all. It makes you look like you have naturally long eyelashes. I would highly recommended this to anyone who doesn't have full eyelashes because it grabs on to all your lashes and divides and lengthens them. A great product!
