I have some acne on lower back and shoulders. Do I treat them like my face? I use Tretionun (1%) and it requires for me to put it on at night and I have to wash my the acne with non-drying soap half an hour before using it.
As you can see, the soap would be hard to get on the back and it would be troublesome.
Any suggestions? Is/would the acne be weaker on the back than the face as to less pores?
