Back acne is embarrassing. Here's what I did that helped me. First, cleanse w/ a gentle cleanser that does NOT have alcohol or fragrance in it. It will only dry out or irritate your skin. This can actually cause your skin to produce more oil which will lead to more acne. Irritating your skin will also cause you to break out. So, you just need something that will be effective at removing dirt & oil. Second, exfoliate. Most people either skip this step altogether or do too much. I recommend exfoliating dry or sensitive skin only once per week; oily or combination skin 3-5 times per week, and normal skin everyday. Finally, to help heal existing acne, you can use a benzoyl peroxide spot cream...but you must be consistent with it. Also, it is not necessary to use something in a high concentration (i.e. 10%) as this is usually too drying. Something in a 2.5% or 5% concentration is all that is needed. Use consistently & it can be very helpful. This is what I found to help me. I hope you find some relief...it's hard dealing w/ back acne...you can't even wear the clothes you want to sometimes for fear of someone seeing (or judging) you. Good luck.
