Acne Mechanica: Meaning, Causes, Treatment

Acne takes on many forms and has a multitude of triggers, ranging from hormonal imbalances to medication usage and beyond. Among them is acne mechanica, a type of acne induced by constant friction or pressure on the skin. In this insightful blog, we delve into the specifics of acne mechanica, its underlying causes, and potential treatment options.

What is acne mechanica?

Acne mechanica is a variety of acne that develops when the skin experiences excessive rubbing, squeezing, or stretching. It can arise from preexisting acne or can appear independently without any underlying outbreaks.

Similar to acne vulgaris, acne mechanica can lead to inflamed skin lesions, including papules, pustules, and nodules. The recognisable pink and red bumps are papules and pustules. The more serious, deeper lesions known as nodules can be quite painful.

You will commonly come across acne mechanica cheek. But this form of acne can appear on any body part frequently exposed to pressure or friction. For instance, you will also find acne mechanica forehead. Other areas where acne mechanica can appear include the arms, legs, buttocks, torso, and more.

What causes acne mechanica?

Acne mechanica may occur when skin is constantly subjected to friction or pressure. This can happen from wearing certain clothing or remaining in one position for extended periods. Some of the most usual triggers of acne mechanica are as follows:

  • Clothing, particularly shirts with collars
  • Sporting equipment, such as football and hockey gear
  • Accessories, like hats or bras
  • Medical tools, including casts and surgical tape
  • Hands, when repeatedly rubbing against the skin
  • Seating, such as chairs or car seats

Repeated friction on the skin can put anyone at risk of developing acne mechanica. However, certain groups are particularly vulnerable to this condition, including

  • Individuals who engage in sports and must wear restrictive gear, like professional or student-athletes
  • People whose daily routine requires them to remain in one position for extended periods, such as truck drivers
  • Those on bed rest are also more prone to developing acne mechanica
  • Those with conditions that involve rubbing or squeezing of the skin, like autism spectrum disorder (ASD) or anxiety

It's worth noting that individuals who already suffer from acne vulgaris may also be more susceptible to developing acne mechanica as a complication.

Acne mechanica treatment: Our top tips

How to prevent acne mechanica

Some preventive measures to tackle acne mechanica include:

  • Opt for loose, soft clothing and avoid constraining accessories. If you have a delicate complexion, it's crucial to select garments that are gentle on your skin and won't agitate it. Always choose something comfortable to wear regularly, whether it’s your bra, hat, or some other item.
  • If you are an athlete, remove your sports equipment as soon as you are done with the activity. Moreover, wash your skin right after completing an athletic activity and removing your sports equipment.
  • Be aware of how you handle your skin. Repeatedly touching or massaging it can result in harm. While it may seem harmless for some, this habit can lead to acne mechanica and cause issues.
  • To prevent acne mechanica, try incorporating more breaks into your day. Giving your skin a rest from constant pressure can be as easy as taking a brief stretch or investing in supportive cushions for sitting.

Conclusion

Acne mechanica occurs when the skin endures constant friction or pressure, leading to breakouts. The key to treating this type of acne is identifying and eliminating the root cause. This often involves removing anything that causes pressure or rubbing on the skin. Along with addressing the cause, it is crucial to allow the skin to have ample "breathing" time by avoiding any coverings or bandages. Once the source of the breakout is gone, acne mechanica can be effectively managed through the right skincare products.

FAQs:

1. Is acne mechanica the same as acne vulgaris?

While it is true that both forms of acne can result in skin inflammation, it is important to note that acne mechanica and acne vulgaris should not be treated as interchangeable conditions. Unlike acne vulgaris, which is often linked to changes in hormonal levels, acne mechanica is solely triggered by mechanical factors.

2. Does acne mechanica cause pain and swelling?

Acne mechanica can cause regular small and red bumps like pustules and papules. But they can also cause nodules that are bigger and often extremely painful.

3. Can I use moisturiser when I have acne mechanica?

If your skin receives adequate moisture, it will be safe from constant friction and rubbing. Therefore, using moisturisers can help lower the risk of acne mechanica. Additionally, moisturisers will help control sebum production and prevent acne vulgaris. If you get acne vulgaris, you have a higher chance of developing acne mechanica. Therefore, preventing acne vulgaris with adequate moisturisation will help cure acne mechanica.
