I agree with beautylovingirl that it would be easier to suggest products for you with more description of what you have and haven'y used and what type of coverage and finish you prefer.
However I have combo skin that is acne prone also. My favorites are Lancome Teint Miracle (light-medium coverage, builable, has a more "radiant" finish but not sparkly), Lancome Teint Idole (medium-full, buildable, natural finish), and Kat von D Lock-it (full coverage, satin finish)/
Oh Dear , I used to have the same issue until I discovered
Chanel Vitalumiere Aqua liquid foundation . Which work wonderfully for my Combo Acne prone skin . Trust me you will not be disappointed , because it's water base with SPF 15 Broad Spectrum . Good Stuff try it
