I've recently finished up a bottle of this primer. I'd been using it on and off for just under a year and even though there isn't a lot of product in this ( that is something that annoys me about elf products, yes they are cheap, but a lot of their items have such a tiny amount of Product! ), it lasted well because you only need a small amount.
I like the packaging, it's sleek with a nice pump applicator. If you turn it upside down, you can sort of estimate how much product is left. Of course, the packaging is much bigger compared to the little amount of product that's in it.
The actual primer is a bright green and looks sort of scary to put on your face. It does glide over your skin like silk though and once it's over your face, I couldn't see and difference that the green made. I get redness in my cheeks and on my nose and this didn't help disguise that. It does however, make my foundation smooth on better and it helps to fill in the pores a bit on my face. I'm not really sure if it helps make my makeup last longer and i don't really have fine lines to see how it goes on that.
Overall, I'd probably pick this up again. I do think as a normal primer it works well but if you want redness cover, than try something Else! I think iherb has this the cheapest but only if you buy a few things to justify the postage costs.
So this product is good but since using other products and seeing other results Id say this is average. Its great if you are on a budget and need something affordable but I felt that my makeup sat on top of the primer and even with a setting spray its still didn't set, I felt as if my makeup was moving and If I was to hug someone my makeup would fall of onto their shirt. The good side is that it does even out my skin tone and it does create a smooth surface. Also I expected more to be in the bottle due to the size but there was very little.
