We’ve all heard about acne, but not everyone knows there are different types of acne. One of these, called acne mechanica, is particularly common among those with an active lifestyle, like athletes.
This type of acne occurs due to constant rubbing or pressure on the skin, a situation that athletes frequently experience.
If you’re someone who spends hours training or playing your favorite sport, you’ve likely noticed small breakouts on areas like your back, chest, or even face. Don’t worry—we’re here to explain this condition in detail and share tips on how to prevent and treat it.
What is acne mechanica?
Acne mechanica is a type of acne that develops when the skin is exposed to constant physical stress, such as repetitive rubbing, trapped heat, and excessive moisture. These factors clog pores, causing inflammation and leading to the formation of pimples or lesions.
For athletes, this issue is particularly common due to the use of tight-fitting clothing, protective gear, or sports accessories like helmets or knee pads, which increase pressure and friction on specific areas of the body. Additionally, sweat that builds up during exercise creates the perfect environment for bacteria to thrive, worsening the discomfort.
From a dermatological perspective, this acne occurs when hair follicles become irritated and inflamed from constant contact with materials that don’t allow the skin to breathe.
While it can be annoying, understanding its causes and how it affects your skin is the first step in managing it. The good news is that, with the right care, you can prevent it and keep your skin balanced while enjoying your active routine.
Where does acne mechanica typically occur?
Acne mechanica typically appears in areas of the body exposed to direct contact with clothing, sports gear, or accessories that cause rubbing, pressure, and sweat buildup.
The most commonly affected areas include the back, shoulders, and chest, where the combination of tight fabrics and repetitive movements blocks pores, leading to breakouts.
It’s also common on the back of the neck, especially for athletes who wear helmets or tight bands during workouts.
Additionally, the inner thighs are prone to irritation from constant friction with athletic fabrics or accessories, which can sometimes result in blackheads. If this area concerns you, exploring resources on how to help eliminate blackheads on the inner thighs could provide valuable tips for better care.
Adopting simple habits like showering immediately after exercise, wearing breathable clothing, and using appropriate skincare products can help prevent these issues from becoming a recurring annoyance.
Types of acne: Differences between mechanical acne and acne vulgaris
Although acne mechanica and acne vulgaris may look similar, their causes and characteristics are quite different. Here's a comparison to help you understand:

Acne vulgaris |
Causes |
External factors like rubbing, constant pressure, and trapped sweat. |
Clogged pores due to sebum, dead skin cells, and bacteria (Propionibacterium acnes). |
Affected Areas |
Shoulders, back, neck, and areas in contact with tight clothing or helmets. |
Face, chest, and back—areas with high sebaceous gland activity. |
Trigger Factors |
Tight clothing, sports gear, and sweat buildup during physical activities. |
Hormonal fluctuations, especially during adolescence or hormonal changes. |
Acne mechanica symptoms
Acne mechanica has a set of characteristic symptoms that make it easier to identify, especially if you’re an athlete or lead an active lifestyle. The most common signs include the appearance of pimples or papules in areas exposed to constant rubbing.
In addition to visible lesions, the skin in affected areas may become red and inflamed, causing discomfort when touched. Another frequent symptom is a rough or uneven texture, which results from repeated damage to the skin’s surface due to pressure and trapped sweat.
These symptoms can worsen if left unaddressed, especially when pores remain clogged. Incorporating the use of gentle soaps and ensuring your skin stays clean after workouts can make a huge difference in preventing and soothing these issues
What causes acne mechanica?
Acne mechanica is caused by several external factors that impact the skin. Here are the most common causes:
Friction and Pressure
Constant contact between the skin and tight clothing, backpacks, helmets, or sports gear is one of the leading causes of acne mechanica.
Repetitive rubbing irritates hair follicles, leading to inflammation and clogged pores. To prevent this, products like a body block to fight friction can help minimize the effects of constant friction.
Excessive Sweating
Sweat trapped on the skin mixes with oils and bacteria, clogging pores. This warm, humid environment becomes an ideal breeding ground for bacteria, increasing the likelihood of pimples and papules.
Areas like the back and chest, where sweat tends to accumulate, are particularly vulnerable.
Heat and Humidity
Hot and humid conditions, often experienced during intense physical activities or in warm climates, contribute to the development of acne mechanica. These factors stimulate sweat production and sebaceous gland activity, worsening pore blockage.
Tight Clothing and Sports Equipment
Wearing tight clothing or sports gear that exerts constant pressure on the skin is another major cause. Materials that don’t allow the skin to breathe, such as synthetic fabrics, intensify irritation and trap sweat, leading to breakouts in areas like the shoulders, back, and chest.

What are the treatments for acne mechanica?
Treating acne mechanica involves addressing both skin irritation and pore blockage. The key is to combine a proper skincare routine with specific products that reduce inflammation, control bacterial growth, and improve overall skin health. Here are some effective treatments:
Gentle Soaps and Creams
The first step in treating acne mechanica is keeping the skin clean and soothed by using gentle soaps that remove sweat and dirt without causing irritation. To improve skin texture and reduce lesions, you can apply a cream for bumpy skin, designed to smooth rough areas affected by friction.
Benzoyl Peroxide
Benzoyl peroxide is one of the most effective ingredients for fighting breakouts caused by acne mechanica.
Its antimicrobial action helps eliminate bacteria from the pores, while its anti-inflammatory properties reduce redness and swelling. Using creams or gels containing this ingredient can significantly improve the appearance of affected skin.
Antibiotics
In more severe cases, dermatologists may prescribe topical or oral antibiotics to control bacterial infections and reduce inflammation. These medications work from within, helping to prevent new breakouts and heal affected areas faster. However, it’s important to use them under medical supervision to avoid bacterial resistance.
Vitamins
Essential vitamins, such as vitamin A (retinoids), C, and E, can benefit skin impacted by acne mechanica.
Vitamin A helps regulate sebum production and promotes skin cell renewal, while vitamins C and E act as antioxidants, aiding skin regeneration and reducing inflammation. Including these nutrients in your diet or as supplements can enhance your skin’s long-term health.
By combining these treatments and following a consistent routine, you can effectively manage acne mechanica and maintain healthier skin.
How prevent acne mechanica?
Preventing acne mechanica involves taking care of your skin before, during, and after physical activities. Here are some practical tips to keep your skin healthy and avoid breakouts:
1.- Wear Sweat-Wicking Clothes
Choose breathable fabrics that wick away moisture and allow your skin to breathe. This helps reduce sweat buildup and prevents clogged pores.
2.-Keep Skin Clean
Shower immediately after exercising to remove sweat, dirt, and bacteria. Use gentle soaps for a thorough yet soothing cleanse.
3.- Avoid Tight-Fitting Clothing for Long Periods
Limit wearing tight clothing like compression shirts or leggings for extended periods. Opt for looser garments when not training to let your skin rest.
4.- Use Products That Reduce Friction
Apply specific products before workouts to minimize damage from constant rubbing. Try a body block to fight friction, to protect areas prone to direct contact.
5.-Moisturize Regularly
Keep your skin well-hydrated with lightweight lotions to prevent dryness and irritation. Creams with calming ingredients can improve skin elasticity and reduce inflammation risks.
6.- Choose Breathable Sports Gear
Ensure your sports equipment, such as helmets, pads, and backpacks, is made with materials that allow airflow to avoid overheating your skin.
7.- Visit a Dermatologist When Needed
If your acne persists despite following these tips, consult a dermatologist for more tailored treatment options.
By incorporating these habits into your routine, you can effectively prevent acne mechanica and maintain healthy, balanced skin.
