Sunscreen Recommendations that are Anti-Blemish or Acne Safe to replace AM moisturizer?

I've rarely ever worn sunscreen, yet spent most of my young life out in the sun. I now know that it's something vitally important to good skincare and really need help finding good sun protection. The most recent routine I've settled into has worked amazingly- resulting in the most clear skin I've had in years (I'm still in the purging stage, but the dark, deep and painful nodules clustered in my cheeks for months and months have finally abated).

I'm looking for a product that will compliment or add to my current anti-blemish routine, replace a morning moisturizer, and go on light.

I don't wear makeup, so a sun protectant playing nice with foundation isn't a concern. I do however need something that won't be compromised by sweat as my vehicle doesn't have AC and tends to get quite hot inside as the weather turns from mild to scorching. Any suggestions?
