I like the Sonia Kaskuk foundation brush (from Target) and it's only $10. Whoops, you said MAC or Sephora...I'm sure Sephora (Sephora Brand) has a nice one. I personally have always liked loose powder. I don't know why? Maybe b/c I've never needed/wanted alot of coverage.
Since you have acne prone skin, Neutrogena has makeup out that has Salycic Acid in it to help control acne. I have the Clean Tint foundation and really like it.

I hope this was helpful...
