I used the oxyoyl bar on my buttocks to clear my acne/folliculitus, and left it on the skin over night. I did this for about a week, as I was extremely encouraged by the disappearance of my butt acne. Now, my butt cheeks have a really bad rash, and basically look like one big burn mark is covering the area. Is is possible that my mistreatment of the medication led to permanent damage? Is my skin going to look like this forever now?
