Mechanic: What causes black spots on my back?

Pimples, blackheads, blemishes, acne is the most common skin disease in the United States. Between 17 million and 45 million people have some form of acne, says University of Maryland Medical Center. It exists in many forms and can be developed in many places. A common type of acne are pimples, which develop frequently in the back. Read more below why and don’t forget to¬†click here.


Hormones are the main cause of black spots on the back. When hormones arise, says the American Academy of Dermatology, the body produces more sebum, which is the oil produced by the sebaceous glands to lubricate the hair and skin. The hair follicles obstruct the sebum, which sometimes closes and forms a closed comedo or white spot. When the clogged pore remains open, the oil darkens, which is called an open comedo or black spot. The greasier parts of the body, including the upper back, are more prone to different forms of acne, including blackheads.


Friction of tight clothing and backpacks can cause acne breakouts. Mechanical acne is a type of acne caused by heat, constant pressure and repetitive friction, says the American Academy of Dermatology. If you’ve been on a long walk with a backpack, for example, you may discover an outbreak of pimples on your back. People who have a predisposition to acne on the back are more likely to develop mechanical acne.


Although there are many cosmetic ads that are oil free and non-acne producing, you might think that it is not a concern when it comes to your back. But moisturizers or oil-based sunscreens can clog pores, so the American Academy of Dermatology recommends the use of products labeled “non-comedogenic” or oil-free. In people with longer hair, hair products can be a problem as well. In case the hair touches the back, the products in the hair or even the own greasy hair can trigger an appearance.


Your family history and genetics may be responsible for blackheads in the back. A family history of acne is a risk factor. If your parents were prone to acne, you probably will be too.
