ew yeah i know.. i hate mac foundations too..and trust me i'v tried them all and they are just the most hideous thing thats ever happened to my skin
actually, MAC have different foundation. the one that break me out was the one in tube (forgot it's name) when i returned it, i got another one, and it was in a glass bottle, and that stuff is ok. i get like one of two pimple if i wear it continuously for three days, otherwise it doesn't break me out. but LOVED the coverage of the one that break me out.
oh well i guess i can either have good coverage, or good foundation.
