Back acne, also referred to as backne or body acne, are caused by the same factors that cause facial acne. Like the facial area, the back is also prone to develop acne due to the dense concentration of the sebaceous glands. Other areas include the shoulders, back and the buttocks. The difference is that the back, buttocks, and the shoulders are covered with clothing while the face is not.
Back acne can affect both adult men and women in the same way it can affect children. However, it is more common and severe in men than in women.
Back Acne Causes
However, though the cause of acne is not known, there are factors that can trigger and cause an onset of acne. We shall discuss those factors that cause back acne to appear.
The overactive sebaceous glands secrete excessive sebum, an oily substance, due to hormonal changes in the body, especially during puberty and teenage. This is due to the secretion of androgens by the adrenal glands during that period. Androgens are the male sex hormones and this phenomenon is seen in both boys and girls.
Androgens stimulate the sebaceous glands to secrete more sebum, an oily substance. People with acne also shed more skin cells. This thick oily substance causes the blockage of the hair follicles, through which the sebum and the dead skin cells are drained onto the surface of the skin
The sebum and the dead skin cells are trapped inside. First a black head is formed. There are bacteria present on the skin. When they get inside the clogged pore, they have an ideal environment to mltply and cause infection. When bacterial infection sets in, the blackhead turns into a pimple. An outbreak of pimples is called acne.
As the sebum, dead skin cells and the bacteria continue to accumulate inside, the hair follicle continues to swell. Ultimately it ruptures and drains its contents (which includes pus due to infection) onto the surrounding skin. This can cause painful pustules, nodules, and cysts.
Besides the hormonal changes causing acne, there are other factors that can cause back acne in adults and in children. The skin on the back is relatively thicker. Add to it the dense population of sebaceous glands on the back, which makes the back prone to this skin disease.
Genetic factors are an important factor that make you prone to develop acne, including acne on the back and the buttocks. If both parents have has acne, 3 out of their 4 children will develop acne.
If you drive a car daily for long periods, your back does not get the ventilation because it is in direct contact with the back of your seat. This can cause heavy sweating, which can clog the hair follicles on the back.
Pollution and high humidity are other factors that cause you to sweat profusely on the back. Add to it the dust from pollution. This mix can give rise to acne breakouts on the back.
Hot weather too can cause you to sweat more, which can predispose to clog the skin pore. This will cause back acne and breakouts. Add to that wearing of tight and nonporous clothing, which makes you more prone.
Children and teenagers too can get back acne due to the heavy backpacks they take to school or college. This causes more sweating and the tight straps cause pressure on the hair follicles and clog them.
