I have mixed feelings about this product. I bought this with the Tarte Lights, Camera, Lashes! mascara (which I love) during a sale. When I use this primer with the Tarte mascara, I don't notice a huge difference from when I don't use the primer. I also find that its white color is difficult to cover -- I have to apply coat after coat of black mascara on top. That said, I tried this under my Maybelline Great Lash (which I don't like) and it made a HUGE difference. It made my lashes longer and fuller and they didn't clump. That was a pleasant surprise, but I still don't think that justifies the price point. Honestly, just invest in a good mascara (by good, I mean a regular mascara that does the job for you) and forget about this pricey, pointless primer.

I'd say this product does somewhat what it says. Doesn't work miracles but keeps my mascara on my lashes, helps add volume and length. It's kinda odd in a way as it's white, but this way I know that I've fully coated all my lashes. Then when I add my mascara, again when all the white disappears I know all my lashes are fully coated. Now I knew this was a great primer because Light Camera Lashes doesn't stay on my lashes at all. Give it a few hours and it's all over the place, this is the only one that does that. Anyway, with this primer it actually stays put!! So to me this is a win win!
