why do we get spots on your back

As if it weren't enough to get acne on the face, it can also crop up on your chest and back. According to Acne. org, studies have shown that most people with face acne also suffer from some form of body acne. The back and chest's thicker skin and larger pores can also result in more severe cases of acne than that of the face. According to the American Academy of Dermatology, the exact cause remains a mystery but acne regardless of location is the result of a combination of excess oil, clogged pores, bacteria and inflammation. When the pores are clogged, typically with dead skin cells, the skin's natural oil is trapped within the pore and builds up creating a breeding ground for bacteria to flourish resulting in inflammation. If the skin is blocked at the skin's surface, it will result in mild acne such as blackheads and whiteheads.


The deeper the infection, the more severe the acne can be. When you sweat from exercising or overexertion, the sweat beads on your skin, then mixes with the oil and toxins at the skin's surface. Left there, pores can become irritated or clogged resulting in acne. It is recommended to shower immediately following excessive sweating to rinse the sweat and toxins from your skin. Tight fitting clothing, especially clothing made of material that does not allow your skin to breathe, can be an irritant that results in acne. Though the back can be hard to reach, it is important to wash your skin with a mild soap no more than twice daily to help prevent and treat acne. Pat skin dry with a clean, fresh towel following showering. Rubbing skin can irritate acne further.


Wear clean loose fitting, breathable materials such as cotton to help prevent back and chest acne. Acne mechanica is form of acne caused by irritations, most commonly found on the back. Acne mechanica is the result of something rubbing against the skin repeatedly such as backpacks or weightlifting machines. Over the shoulder straps can also irritate the skin on the chest. Acne mechanica is also aggravated by moisture, so if you combine a backpack with a shirt that doesn't enable your skin to breathe, acne can result. Sheets and other materials constantly in contact with your skin can absorb the oils and dirt from your skin building up over time. This also provides a breeding ground for bacteria. If sheets and blankets aren't washed regularly, at least once per week, then the buildup can cause body acne on the back and chest.
Acne is mostly associated with blemishes that appear on the face, but it can also show up on other parts of the body.


Arms and back are particularly vulnerable to developing acne, which can make it difficult to wear tank tops, backless or strapless clothing. While there are treatments available for body acne, it is important to understand the causes of this condition so you can help prevent triggering arm and back acne. Sweat can easily cause your body to break out with acne, particularly if you do not take a shower as soon as you finish exercising. While sweating is generally speaking positive for your skin since it opens your pores, it can also irritate your present acne and cause your pores to be open for additional bacteria to accumulate on.


Living in a place with hot or humid weather in particular can contribute to acne on your back and arms. Areas like your arms, neck and back have more sebaceous glands (that secrete an oily substance called sebum) than other parts of your body, besides for your face. The locations of your body that have more sebaceous glands also contain more oil, which causes your hair follicles to have a higher chance of getting clogged with dead skin cells, causing irritation to your skin, as well as acne. Friction is another contributor to acne on your arms and back. Rubbing your skin excessively can make your current acne even worse and even cause new breakouts to occur. Wearing restrictive clothing, such as a tight shirt, purse strap or backpack can cause irritation to your skin and potentially acne as well.


Androgens are a typical male hormone that can create acne, especially the kind that appears on the back and arms. These male hormones can also make your sebaceous glands bigger and subsequently produce more oil than usual, which leads to clogged hair follicles and acne. The female hormone called estrogen can also cause acne. When a women menstruates, her estrogen levels can vary widely, which can cause acne breakouts on the back and arms in particular. Using birth control pills can help prevent these breakouts for some, but worsens the problem for others. Allergic reactions to the ingredients contained by your fabric softeners, laundry detergents and dryer sheets can also inflame and irritate your skin, leading to back and arm acne.
