The best thing I've found for my acne (on my chin only) is lush angel on bare skin cleanser.
I've spent nearly £1000 the last couple of years trying to combat it and this is the only thing that works for me. I saw a difference in 4 days.
It's £7 odd a tub but it lasts a while.
I think my skin was reacting to the chemicals, it's balanced my oily bits and make my skin feel lovely and soft whilst also clean, the bonus is it's cleared up my acne.
