This is the BEST, ONLY PRIMER I will use. It makes my last nice and thick and ready for mascara.

This primer blends really well with other brands of mascara and it doesn't get clumpy after its dried. There is a noticeable difference in length after applying

This is a great Primer and lasts all day. It helps my mascara from running and seems to help my lashes as well.

While this primer does prime and protect your lashes from regular mascara wear, its application is extremely wet and tends to clump lashes together in chunks. The applicator has a brush side and a toothed side for separation; however, the teeth on the separator side are a little too far apart to achieve any proper definition. Tip: after applying your regular mascara over this primer, spend a few minutes separating your lashes and combing through excess product using a bare spoolie. This will help achieve a more feathered natural look.

I don't usually use lash primers that often but I can tell the difference when I use this. Has a great brush and doesn't clump!

this mascara is so nice, I love how black it is and how it lengthens my lashes. it def volumnizes them! highly recommend.

I usually use a different primer but tried this one out and I am really impressed. I am hoping it has staying power and the quality doesn't diminish significantly over time as I have had occur with our primers.

I never thought a mascara primer was necessary but applying this before my mascara makes a big difference (my lashes appear longer, stay curled longer, and my lashes don't clump! Also, this primer lasts a while! Lots of product and the primer has stayed moist over a year.
