Why should Acne on back be managed by a dermatologist?

How could the acne on back sufferer be sure that it is acne and not another disease?

How could he/she tell about the response to treatment?
Acne on back should be managed by a dermatologist because of diagnostic and follow up difficulties.

There's an inherent inability to precisely recognize back lesions and follow up their progress during the course of disease or its treatment.
Failure to recognize lesions on back would hinder perception of their exact nature and extent. This particularly applies to changes in appearance or density especially of deep lesions or those raised above the skin surface such as nodules and cysts.
Consequently, the discovery and follow up of the progress of abnormalities and complications as well as judgment by the back acne sufferer upon resolution or response to treatment is not practical. As the sufferer is always oriented with acne, because it's a common disease and because of the limitations in perception, these lesions are either neglected or misinterpreted as an acne lesion.

Remember that; because you can't inspect your back easily, you need to make sure that your spots heal and that the condition is not another disease that you are misinterpreting as an acne lesion. Please consult a Dermatologist.

Why is Acne on back difficult to prevent?

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. The back is also in constant contact with clothes and especially when tight, might irritate the skin, which can further aggravate the condition. 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.

Why are Acne on back lesions lately discovered?

The back is beyond the limits of the normal human visual field and therefore, any changes in its appearance as caused by disease are not recognizable. That also means, whenever an abnormality develops in the back, it is not detected and is not complained of as a symptom.
That particularly applies to changes in appearance of the skin surface of the back and to add most of the abnormalities resulting from acne i.e. comedones which are only visually detected. Accordingly acne on back projects into consciousness mainly, when pain and or itching is associated with the inflammatory lesions.
The back is hidden from the public eye due to clothing, consequently, it's not noticed by others especially family members who would direct the back acne sufferer's attention to these lesions.
The consequences of this simple fact are:
Late discovery of the lesions of acne on back (usually when severe or complicated).
