Great product

I have been using this product under my dior show mascara for years and I love it. It enhances the mascara and allows it to stay on for hours perfectly. You need to know how to use it though. Don't let it get dry before you put your mascara on and don't do it immediately when it is too wet. I apply this primer to both my lashes and immediately follow with the mascara. So while I'm applying the primer to the second eye, the first eyelash dries up for couple of seconds so when the mascara goes on its not too wet to mix with it and not too dry to fight with it!

Not so much...

I love, love, LOVE primers, but this was a disappointment for me. The Prep + Prime line is the only MAC product that I still currently use, so I thought I'd be a fan. Unfortunately, it seemed to have a wet consistency on my straight lashes. I tend to draw toward dry formulas of any kind of lash product. The primer just weighed down my eyelashes and didn't yield any results, significant or otherwise.

Dramatic Difference

This lash primer is EVERYTHING. My MAC mascara already made my lashes dramatic but this primer is drama times ten. People ask me if I have false lashes on - yes, this product is THAT good. I will never wear my mascara without primer again. It really lengthens the lash and spreads them out. Buy this now.

Perfect Primer !

I love this lash primer. It makes my lashes look longer and thicker. It enhances the look of ANY mascara you use. I have tried many other primers and this is the absolute best ! If I could give a rating of ten stars, I would !!

Great product

Love this primer, I immediately noticed a difference when I first used it. My mascara went on smooth and my lashes looked full and thick. Mascara never got dry or flaky, helps it to last all day long. Have been using it for over a year and love it!!

Prep + Lengthens my lashes

I was looking for a product which would help my mascara stay in place. This product does just that. The added bonus is that it does make my lashes longer and more full with mascara.

too thin

I've used Lancome lash primers before and decided to try this one out just because it is MAC. I don't love it. I have to build it up by layering. The Lancome one is MUCH better; it makes my lashes look thicker with one single layer. Save your money on tis one and get a Lancome primer instead.

"Great Product"

So glad I bought this product! I always had problems with my mascara clumping. Using the Prep t Prime makes such a difference especially in the warmer weather! It really does help to separate your lashes so you don't have spider lashes! From now on I'm a true believer!

Not a good product

Didn't work for me. Wanted to try something different and was disappointed.

Amazing

What a great product! Once I started using a serum for my lashes like this, my makeup life changed forever. I love the full, soft lashes I have now after using this product for awhile. Another serum that is really awesome and a lot like this one is Measurable Difference's Lash and Brow Amplifying Serum. I use both products on and off and get great results.

Pretty darn good

I bought three different brands of lash primer to test after finding my favorite Shisedo one has changed its formula. I like this one; it goes on easily with the brush. It makes lashes a bit spiky rather than thick, but that works OK since it doesn't clump up. It holds my waterproof mascara on, and cleans easily w/ my remover. The only thing that it doesn't do as well for me as the Shisedo, is to hold the curl I put on my lashes. The Shisedo did the very best curl hold of all products I've tried. Too bad they changed it!
