Poor Skin!!!! Adjusting to Washington, DC

Since my move to Washington, D.C. in July this past summer, I've been on the go constantly. This has been quite the transition for me. I grew up in Florida and attended college in Florida. I was a Florida girl for two decades. But grad school beckoned me to D.C. I packed what I could fit into my jeep, uprooted from a comfy apartment, and dropped off my miniature pinscher at my mom's house. Enter D.C.: later nights, no dog, more homework, and whaaat? Pimples?

I never had a skin problem until I relocated here. I always had clear skin with what I considered the perfect balance of freckles and tan. I wore sunscreen and moisturized frequently but the air in southern Florida kept my skin healthy without much effort. With the natural humidity Florida is blessed/cursed with, I never had a problem with trying to figure out the balancing act of moisturizer + oil controlling products. This has become a new challenge for me. Since July, I've been testing out new products, mostly over the counter. I finally decided to drop the money and the effort to order Proactiv. It has been working but it's only been a couple of weeks and I alternate with other products from Clarins.

I'm interested in getting input on those who use or have tried Proactiv. DOES IT REALLY WORK like Jessica Simpson says it does?
