I was lucky enough to get a free sample of the smashbox photo finish primer, and i loved how much smoother my skin seemed afterwards, and how long my make up lasted. I only use it now if I am going out somewhere special as it is pricy, wish I could get more free samples!

I use the Rimmel Fix and Perfect on my face and the UB on my eyelids when going out to humid bars or clubs and my makeup doesn't budge all night!

I don't really use any primers on my face, except for my eyes. I find that the primer holds on my eye shadow, which allows for a longer wear during the day. Other than that, it's just a tinted moisturizer.

I bought Palladio Herbal Eyeshadow Primer based on the rave reviews it got on MakeupGeek, and I swear by it. I always had weepy creases on my upper lid, and honestly this primer holds everything in place from the time I leave for work, until after-work drinks are done. Bold eyes aren't a problem for me anymore ;)

I love the Lisa Watier eye primer. Its less expensive then UD (which I also love) but not worse in quality. 1 tube lasts for months. Good stuff :)

Benefit's "Porefessional" is awesome!

I tried a couple different primers and I didn't like it. While it made my face feel soft, it also felt oily. My foundation glided over it, but it actually made it seem to last a shorter period of time instead...like it glided right off in some spots, creating a patchy look. I still have a couple full bottles, but I won't use them ever again.

I've been using Maybelline Age Rewind Primer. I like it so far, but admit it's the only one I have tried.

I still don't use a face primer, although I think bb cream counts. I do use my NP set eye primer on rare special occasions when I really need my eyeshadow to stay put all day, but I hate to waste it because it was so expensive for a tiny little bottle. I tried a mascara primer before, it was on one of those double sided mascara tubes like #9 in the last set. I noticed a difference in the fact that my eyelashes looked ridiculously long, but I wasn't quite sure if that was from the primer or the new mascara. Unfortunately I had to give it away because it really irritated my eyes. I am not really gung-ho about trying another one though, because I feel like my lashes are doing perfectly fine without it.

I loove primer! I use Smashbox Photo Finish, and it works amazing. I love the feeling of it on my skin. I'm also a huge Lancome fan, and when I went to purchase the Waterproof Eyecolour Base they didn't have any in stock but she gave me a sample...which is about half the size of their regular one, and it's free. So my tip is to just ask for a sample and it should keep you going for a few months!
