Here is a link I found that will hopefully be helpful. I thought this might be since after starting T your skin becomes more oily and acne increases.

Tip that isn't on here that I found helpful is I have a male face wash and I use it in the morning after i get out of bed and in the evening before bed. It has helped to decrease my acne.
