Acne on the shoulder region: Classification, reasons, and methods for elimination
In the realm of skincare, acne mechanica on the shoulders has been a common concern for many. This form of acne is primarily caused by friction, heat, and pressure, often due to tight-fitting clothing, sports bras, straps, backpacks, or repetitive rubbing in those areas [1][3][4][5]. The combination of friction with sweat and occlusion can exacerbate acne by irritating hair follicles and clogging pores.
Acne can affect various parts of the body, including the face, chest, back, and other areas. Acne mechanica, specifically, develops in response to physical factors such as pressure, friction, and heat.
To combat acne mechanica, a variety of treatment options are available. Topical treatments form a significant part of these options. Benzoyl peroxide, for instance, is an antiseptic that kills C. acnes bacteria on the surface of the skin and inside hair follicles [2]. It is available in gels, lotions, or washes and helps reduce oil, exfoliate skin, and kill bacteria [2].
Salicylic acid, another topical treatment, is a beta-hydroxy acid that reduces acne lesions by exfoliating the skin and removing oil, dirt, dead skin cells, and bacteria [2][5]. It is often used in cleansers or lotions.
Retinoids, such as Adapalene and Tretinoin, promote cell turnover to prevent clogged pores but can increase dryness and sun sensitivity [2]. Topical antibiotics, like Clindamycin, reduce bacteria and inflammation, often combined with benzoyl peroxide [2]. Lastly, Azelaic acid, derived from grains like wheat and barley, can decrease discoloration and swelling of the skin and has been shown to reduce acne [2].
Beyond topical treatments, reducing mechanical friction is crucial. Wearing looser or moisture-wicking clothing and avoiding prolonged pressure from straps or backpacks can help prevent acne mechanica [1][3].
For more severe cases or scarring, in-clinic procedures may be necessary. Chemical peels using salicylic acid, lactic, or glycolic acid can exfoliate dead skin cells, unclog pores, and promote skin renewal [5]. Microneedling stimulates collagen production to improve acne scars and skin texture [5].
Professional dermatological care often involves combination therapies tailored to individual needs and skin sensitivity to optimize results and reduce the risk of antibiotic resistance [2].
In summary, acne mechanica on the shoulders primarily results from friction and pressure, and effective management combines topical treatments, minimizing mechanical irritation, and sometimes professional procedures for persistent or severe acne [1][2][3][5]. If acne persists or worsens despite home treatment, or if more than one painful acne lesion develops, it is recommended to consult a doctor [6].
