I usually use bobbie brown makeup which never broke me out and for some stupid reason I thought let me try mac (biggest mistake ever) my skin started itching and it gave me little white heads which the lead to more break outs took me ages to over come it...........I HATE MAC!!

so I think its the mac makeup that caused yu to break out don't ever put it on again..

I always ask myself that, too. For me, I used Smashbox BB cream and I think it caused me to break out, first I noticed a lot of blackheads, clogged pores, small flesh-colored bumps on my cheeks and later on, they eventually became pimples. Sucked big time. My derm was disappointed that I've been wearing makeup "secretly" and she recommended me to use powder instead of liquid, but I prefer liquid as I find it easier to work with. She says powder doesn't clog as much, but I dunno.

Why not try mineral makeup? It's the only thing that I can wear comfortably, always looks really natural (and not caked on as liquid foundation can), it's mattifing, and actually - depending on the formula - can help your skin! I use LilyLolo, and have been using it for 6 years.
