Skin problems

The winter made my skin dry, which was gross but easy enough to deal with. Now that the weather is starting to warm up, I'm beginning to break out again. I'm not sure if I should start some complicated regimen or just buy a tube of tretinoin and do spot treatments. It's not my entire face. It's mostly the t-zone area. Well, less my forehead and more my cheeks and nose. The I-area? Help!
