I have had acne to my back and shoulders as long as I can remember with it getting worse or better over the years.
I have been to Dermatologist before with minimal effectiveness.
I was getting back facials 2x a month, googles an effective treatment. Using 10% benzo wash 2x, differin gel at night, 10% benzo cream in the morning on any active red breakouts. It helped control things about 75%....
