In brief: 21/2 per cent

Even percentages as low as 2 1/2 percent can decrease acne, although it is available in 4, 5, 8 and 10 per cent concentrations.
4 and 8 per cent body washes is a good approach for back acne.

In brief: Varies

I'd suggest applying 2-3x/day to areas prone to acne.
If you need something stronger, your physician has it.
