I know this thread has been here a little bit, but I just saw it.

I too had struggled with this, I tried tea tree oil, it's very strong, so you only use a drop and mix it with water for a facial wash, or even body wash. You can put the tea tree oil on undiluted for spot treatment to help them heal faster. It even helped heal the cystic acne faster and that takes forever normally.

I still broke out now and again, it's worth a try if the other treatments don't work. The nice thing is is did not burn or dry out my skin, which is already very dry.
