A special back scrubber
With the large surface area of the back, extra effort is required to accomplish cleansing and scrubbing i.e, difficulties associated with the personal hygienic approaches to the back.The remote back or the area farthest from the front is partially beyond the the range of movements of the upper limb and the reach of the fingers--------> Failure of proper ordinary scrubbing during regular wash and the need for a special back scrubber.
Unlike the face, it's not practical to wash the back many times a day especially when the acne on back sufferer is in outdoor site during day time to prevent the effects of the sweaty covered back.
Inevitable daily activities
There are many daily activities that would aggravate acne on back. These practices are considered irritative as they inflict local repetitive minor trauma to the back on a daily basis. Examples of these mechanical stresses include: sitting in a chair for a long time, such as when driving or while working and carrying heavy backbags.

Everyone has to wear clothing and the clothes we wear may be important factors in the causation of acne on back.These factors are inevitable because we all must sit down and wear clothes while working.
