You want to use good skin care both morning and night, which will help with your breakouts and add hydration to help with the dryness. Sounds like you might be over-medicating your acne to be so dry. During the day, just keep your hands off your face and clean your cell phone often to remove dirt, oil, and bacteria. Never sleep in your makeup, either! = )
It's not TOO hard to upkeep your skin during the day! I used to like to keep a light sheer pressed powder to touch up for any shine and even out my skin tone if needed, but if you have dry skin I'd suggest that you invest in a good hydrating face cream with spf that you can wear in the morning to really protect your skin and keep it moisturized.
I LOVE Origins for a good everyday moisturizer, if you have dry skin try the Origins VitaZing which has an SPF 15 and is super hydrating:
If you want a little extra color or coverage, use a BB Cream with hydrating properties too:
Dr. Jart Water Fuse BB Cream
Smashbox Camera Ready BB Cream
