Some people who through no fault of their own and for no foreseeable reason end up with back acne.
This can be a very painful condition which happens to also be quite unsightly.
All this being said diet and exercise, environment and stress can contribute to other factors in clearing it up or causing it to be very much worse.
It will probably be in your best interest to buy a soft sponge on a stick like a back scratcher.
Get the soft sponge and apply anti bacterial and deep cleansing products and very very gently run on the affected areas of your back.
After a few weeks of this it should clear up substantially, but probably not entirely.
In order to clear this condition up entirely without seeing a dermatologist you should purchase a second back scrubbing device with some exfoliation promoting texture.
Use some foaming deep cleansing cleaner and exfoliate your back gently.
Do not cause open wounds or you may suffer from random scarring from the incident in question.
Afterwards continue with a cool shower while applying the anti bacterial as you had before with the former back scrubbing device.
In a matter of weeks you can go from your back covered in painful and unsightly acne to just about none and if your lucky none at all.
Do not stop treatment though as due to your own circumstances and environment you may cause the return of the said acne.
If for some reason no forward progress has been made in the war on back acne after executing the instruction in this article you should seek the guidance of a certified dermatologist.
