I would recommend the SMASHBOX BB CREAM. I have oily/combo skin, with a very oily t-zone. You would not know that with this BB Cream, on. It evens out my skin tone, moisturizes, provides great coverage, and mattifies. Plus great spf. As for acne, I wouldn't know too much. It hasn't caused me to break out, but I don't have acne that needs to be controlled or covered to give my opinion regarding that.
You can ask for a sample at Sephora. They'll make one for you, and you can use that for about a week, before you decide. Which is what I did, before making my purchase.
Strength and Honor,
I've tried a few of the Asian brands of BB Cream including Skin79, Skinfood, Etude House, Lioele, and Dr. Bart. So far my favorite has been the Peach Sake BB Cream made by Skinfood. It's a relatively inexpensive product that you can pick up online. The scent is delightful, a fresh, but not overwhelming peach fragrance.
Like the name suggests, it's meant to dull the appearance of pores. My pores aren't very noticable, so I can't confirm that claim. However, my skin is quite oily and find that this product stays put and doesn't drown my face in over-shine. I don't have much acne either, but I haven't broken out using this product. But of course that varies from person to person.
If this sounds interesting to you, I'm sure you can find sample packets purchasable on ebay for a low price, just to try things out. But like I mentioned before, this product is inexpensive, roughtly $13 or so for a full sized pump bottle.
