I know that the fact that MAC products break people out has been covered already, but after looking through the boards, I still can't figure out WHY. I've done a side by side comparison of MAC ingredients (http://www.specktra.net/forum/list/254) and pore-clogging ingredient lists ...
... and I don't see any of the ingredients in MAC Studiofix Powder or MAC Studio Finish concealer.
I'm asking because I've been getting terrible acne lately, like teenage acne (I'm 26), so I'm trying to use more non-comedogenic makeup. In my years of using MAC, I haven't usually broken out this bad, save for a one or two pimples that I always occasionally get ... this recent breakout was really sudden, and I don't think was a direct result of MAC products. But MAC does feel rather heavy, so I figured I'd do away with it. Except ... it is so hard to find a replacement that's relatively healthy for your skin. Color-wise and texture-wise. I could probably replace Studio Fix, but no other concealer glides on, covers, and blends as well, AND has a variety of shades. (Well, I'm sure other department store brands do, but most of them are even more expensive than MAC). I actually looked up the ingredients of a pretty well loved concealer on MUA, Ben Nye, and it had WAY more pore-clogging ingredients.
Perhaps I should just return to MAC?
