Are you moisturizing? You could be over-drying the skin. When your skin is too dry, your oil glands go into hyper-mode and produce more oil. Even if you have acne-prone skin it's still super important.

Maybe do a home-made face mask every week? You can find some on youtube that might work.

Here's a good one for acne prone skin:

-3 Tablespoons of Honey (organic is better but normal will do)

-1 Tablespoon of Cinnamon

Mix them together and microwave for 25 seconds.

Apply and leave on for 10 min then rinse! (If it burns a little that means it's working!)

Do this weekly and it should help. Good Luck!

First things first, sleep and diet DO make a huge difference, so monitor that. Also, the more sun you can get, the better. I'm assuming you are a guy, so if you shave that could be what's irrating your acne and therefore prolonging it's presence. Switch to an electric razor, to avoid rubbing and nicks, and use only all natural face soap. For acne medication, to really get a good one that will be consistent, have your doctor perscribe you something. If you can't afford it, use neutrogina, night and day. exfoliate (wipe away dead skin cells) with a warm towel, once a week. Gently pat your face with cool water every night. good luck!
