I love the studio sculpt concealer but the foundation oxidized to turn orange and it made my skin very itchy and it broke me out with little texture bumps.

This is a waste of money. The coverage is very poor and leaves a sticky feeling on my skin. I don't like the texture nor the smell of this foundation. I have had no luck with any of MAC's foundation, and this is not the exception. Because the coverage is so poor, you do need quite a bit to get any coverage, but then you end up with this mask like, cakey look. Over the course of the day, the foundation settles into the pores and just looks horrible. I found that it also oxidized on me by the end of the day, and I ended up looking like an oompa loompa.
