Are you using anthing on your acne at all?
If you arnt, I would buy some 5% benzoyl peroxide gel from the pharmacy and some Nutrogena Rapid Cleap Acne Defence Lotion.
I wash my face and apply the benzoyl peroxide at night, then wash my face again and apply the Nutrogena in the morning. This keeps my face acne free, and isnt too drying.
Of course, what works for me might not be whats best for you, so you might need to chap and change a bit, but if you have bad acne, i would definatly be using somthing to help control it.
