Laura Mercier oil-free foundation or MAC studio fix fluid foundation for acne-prone skin?

I have the MAC foundation and it doesn't break me out, but I always wash my face really good before and after using it. I use the studio fix fluid and it really does cover up everything - redness, the occasional pimple, acne scars. The only problem is that it's a little bit too thick for school. But since you're eighteen, I doubt you have that problem. If it really makes your skin look that fabulous, by all means use MAC. Just be sure to wash your face really good afterwards so you don't have to worry about breaking out.
