Acne mechanica
Causes, symptoms and treatment
What is Acne mechanica?
Acne mechanica is a type of acne which occurs as a result of constant friction and pressure against the skin. The breakouts can happen when the skin is rubbed, stretched or wrapped too tightly.
If you already have acne-prone skin, you are more likely to develop Acne Mechanica, however, in absence of any pre-existing breakouts, this condition can still develop on its own.
Just like Acne vulgaris, Acne mechanica presents itself as inflammatory skin lesions such as whiteheads, papules and pustules. In cases of severe inflammation, breakouts may take the form of painful nodules.
Acne mechanica can appear anywhere on the body, but is especially common around areas that have been exposed to friction or pressure. These include the face, neck, scalp, arms, legs, torso and buttocks.
Causes and risk factors
Acne mechanica is caused by repeated exposure to friction and pressure against the skin. It can develop as a result of common activities, such as seating for long periods of time or wearing certain clothes. Some of the most frequent causes of Acne Mechanica include:
- Clothing: e.g. tops with collars, accessories and undergarments such as hats and bras
- Medical gear and sports equipment: e.g. face masks, shields, helmets
- Lifestyle: e.g. having a job which requires seating for longer periods of time
- Habits: e.g. rubbing your hands against your face
Unlike Acne vulgaris which is commonly triggered by hormonal changes, Acne mechanica is caused only by direct mechanical action against the skin, such as friction.
Anyone whose skin is exposed to friction or pressure can develop Acne mechanica. However, depending on their profession and lifestyle, some people are more prone to this condition.
Acne mechanica symptoms
Skin lesions
Acne Mechanica skin lesions may take the form of whiteheads, blackheads, papules and pustules. Depending on the root cause, these breakouts may follow a pattern of friction or rubbing against certain areas of the skin.
Redness & inflammation
Constant direct mechanical action will make the skin more sensitive, triggering redness and inflammation on the exposed areas. Irritation is typically visible across a pattern of areas where the skin was stretched, squeezed or rubbed.
Acne mechanica treatment
Topical treatments: AHAs, BHAs, Benzoyl Peroxide, Retinoids
Medication: oral antibiotics if bacteria is found present or high-strength retinoids
Specialist skin treatments: HydraFacial, Chemical/Laser Peels, Blue Light Therapy
At-home treatments for Acne mechanica
In most cases, Acne mechanica can be treated using at-home topical treatments. Choosing the right creams, serums and face washes is critical to building a strong skincare regime and relieve the symptoms of Acne mechanica. Use a gentle face wash before applying any topical acne treatments to cleanse the skin without causing further irritation.
Products formulated with acne-fighting ingredients such as benzoyl peroxide, AHAs and BHAs are especially effective in clearing up the skin. These are known to kill the bacteria and exfoliate the pore-blocking oil and dead skin cells. Topical vitamins such as retinoids and niacinamide are proven to promote cell turnover and reduce inflammation.

When to see a dermatologist
If you have Acne mechanica that doesn’t respond to standard at-home treatments, it’s time to see your doctor. Sometimes, Acne mechanica may just be the first layer to a more persistent type of acne, such as Acne vulgaris, Rosacea or PCOS.
Your dermatologist will place an accurate diagnosis and prescribe the right medications along with appropriate acne treatment courses.
Oral antibiotics may be prescribed for Acne mechanica, if bacteria is found present. You can discuss more about acne medication with your doctor.
