Dealing with body acne, regardless of age, can be a frustrating experience, especially when it appears in various places on the body. Like facial acne, body acne can be tied to several factors, ranging from a variety of lifestyle habits to environmental exposures. However, understanding body acne mapping and what’s behind your breakouts can help you pinpoint the underlying causes and how to treat each area more effectively.
What is acne body mapping, and how does it work?
Acne body mapping focuses on where acne appears on different parts of the body and figuring out why breakouts occur in these specific areas. Dermatologist Dr. Hannah Kopelman explains, “It’s similar to face mapping, but with body mapping, I often see the breakouts linked more to external factors like friction from clothing, sweat, or product buildup. While some internal factors like hormones or stress can play a role, body mapping tends to focus more on what’s happening outside the body, like your lifestyle and environment.”
What factors contribute to body acne?
While face acne is primarily triggered by internal factors, body acne is generally linked to external influences. However, some internal factors can still play a role. Some of the factors that contribute to body acne include:
Diet
Dietary choices can significantly impact how the skin reacts. For instance, a diet high in sugar and processed foods can lead to inflammation, often resulting in acne. Following a diet rich in fruits, vegetables, lean proteins, and whole grains can improve your skin’s condition, reduce inflammation, and heal your body overall.
Hormones
Hormonal fluctuations—such as those caused by menstruation, pregnancy, puberty, or stress—can trigger body acne. Fluctuations often lead to an increase in the production of sebum, clogging pores and causing breakouts.
Clothing
Wearing tight or non-breathable clothing can trap sweat and bacteria against the skin, creating a breeding ground for acne. Items like sports bras, gym gear, or tight-fitting clothes can cause or worsen this condition if not changed and washed frequently.
Hygiene
Hygiene is one of the most critical factors that often determines your acne. Simple habits like not showering after a workout or wearing dirty clothing can lead to clogged pores, resulting in breakouts. It’s essential to clean your skin regularly, especially after sweating.
Environment
Humidity, pollution, and exposure to toxins can all increase the likelihood of body acne. Sweating in hot or polluted environments without washing your skin thoroughly can exacerbate the problem.
Chemicals and Other Toxic Ingredients
Skincare products, lotions, or even laundry detergents containing harsh chemicals can irritate the skin, causing breakouts. Gentle and hypoallergenic products are best to minimize breakouts in these situations.
Acne on different parts of your body: What does it mean?
Each area of the body can provide clues to what’s causing your acne based on the different causes found and how you can treat them going forward.
Scalp
Causes:
Scalp acne is often triggered by a combination of factors, such as not washing your hair frequently enough or skipping a wash after sweating, which can lead to the buildup of oil and bacteria. Irritation from certain hair products containing harsh chemicals can also clog pores and cause breakouts, especially if you use heavy hair oils that trap dirt. Additionally, wearing dirty hats or hair accessories can introduce bacteria to your scalp, worsening acne.
Treatments:
While you don’t want to over-wash your hair, try aiming for at least two or three times a week and always after sweating. Also, opt for gentle, sensitive hair products like dandruff shampoo, and steer clear of using oils on the scalp as this can clog pores. Don’t forget to regularly wash your hats, headbands, and other accessories to keep the bacteria at bay.
Neck
Causes:
Neck acne can be caused by several factors, including using certain makeup products and dirty brushes, which can transfer bacteria to your skin. Hair products, oils, and perfumes that rub against the neck can also clog pores, and shaving irritation or harsh shaving products can trigger breakouts. Tight clothing like turtlenecks and collared shirts can also trap sweat and bacteria, particularly if you don’t shower after sweating, such as after a workout.
Treatments:
To treat and prevent neck acne, try wearing your hair up to keep hair products off your neck, and avoid using comedogenic products or perfumes that could irritate your skin. Washing your clothing in hypoallergenic detergents can also reduce irritation that may transfer from your clothing. Most importantly, be sure to include your neck in your skincare routine. Especially for those who blend their makeup into their neck, cleansing the neck should be as thorough as the face.
Chest
Causes:
Acne on the chest is often caused by hormonal imbalances and stress, which can lead to increased oil production and clogged pores. The buildup of sweat, oil, and bacteria, especially after exercise, can further aggravate the skin and wearing tight clothing without changing after sweating traps these irritants against the skin. Poor diet, food sensitivities, and allergic reactions also play a big role in chest acne and should be monitored carefully if you notice an increase in breakouts.
Treatments:
To treat and prevent chest acne, it’s essential to shower after sweating and avoid using heavy perfumes or lotions that can clog pores. Wearing breathable, loose-fitting clothing can also help the skin stay cool and dry. Following a well-balanced diet while managing stress levels can also help balance hormones, especially during PMS. HUMs Hormone Balance uses estrogen to provide support in balancing symptoms during PMS like cramps, mood swings, and irritability. It can also help balance the fluctuation in mood and keep hormonal acne under control. If you are prone to rough PMS symptoms or experience worse-than-normal acne, this supplement may be just what you need.
Back/Shoulders
Causes:
Back and shoulder acne can be triggered by several factors, including wearing tight clothing or sports bras, which can trap sweat and bacteria, particularly under bra straps where acne is common. Wearing unwashed workout gear further aggravates the problem by allowing bacteria to build up on the skin. Additionally, harsh hair or laundry products can irritate the skin, leading to breakouts.
Treatments:
While most typically shower once a day, those who work out or have demanding jobs where they might get sweaty and dirty should shower immediately after to clear their skin from dirt, oil, and bacteria. As far as what products to use in the shower, Kopelman recommends products with ingredients like salicylic acid, benzoyl peroxide, or tea tree oil, as they help target acne by unclogging pores and reducing inflammation. Exfoliating body washes are safe to use, but don’t use them every day as they can be irritating. While washing your body is a no-brainer, don’t forget that your workout gear also gets dirty and needs cleaning regularly, too.
Arms
Causes:
Acne on the arms is often caused by excess oil production, which can clog pores and lead to breakouts. Irritating lotions or laundry products that leave residue on the skin can further exacerbate the problem while wearing tight clothing can trap oil and bacteria against the skin.
Treatments:
To manage arm acne, it’s helpful to use acne-specific body washes and exfoliate or dry brush a few times a week to remove dead skin cells and prevent pore blockages. For stubborn spots, salicylic acid or benzoyl peroxide can be used to target specific breakouts. Choosing non-comedogenic hypoallergenic products can also help reduce irritation.
Pubic Area/Booty
Causes:
Acne in the pubic area and on the booty is often caused by wearing tight-fitting clothing (e.g. leggings) or non-breathable underwear, which can trap moisture and create the perfect place for bacteria to grow. Shaving in an area with sensitive skin can often lead to irritation and breakouts, while using scented products (such as for hair removal) can disrupt the delicate pH balance of the vaginal area, causing further issues.
Treatments:
To prevent and treat acne in these sensitive areas, it’s important to shower after sweating and put on clean, breathable cotton underwear to allow air circulation. Going without underwear at night can be a great way to let the skin breathe. As for products, using a pH-balanced cleanser or an unscented, hypoallergenic soap are the best choices and can avoid pH disruption. Still, taking other measures when removing hair can be beneficial. Kopelman says you can also “gently exfoliate a day or two after shaving to help prevent ingrown hairs.” Just make sure not to over-exfoliate, or you may further irritate the skin.
Thighs/Legs
Causes:
Many variables can trigger acne on the thighs and legs. Irritating soaps, lotions, or laundry products can cause inflammation and clog pores. Tight clothing can also trap sweat and bacteria against the skin, while ingrown hairs from shaving or waxing only further aggravate the issue by blocking hair follicles.
Treatments:
To manage acne in these areas, switch to hypoallergenic products that are gentle on the skin and wear looser, breathable clothing to reduce irritation. Regular exfoliation can help clear away dead skin cells and prevent clogged pores from occurring, while gentler shaving techniques can minimize the occurrence of ingrown hairs, reducing breakouts. Kopelman says, “After-shave or other soothing products can really help if you’re dealing with irritation, razor burn, or ingrown hairs from shaving.” She suggests looking for products with ingredients like aloe vera, witch hazel, or chamomile, which can all help calm the skin and reduce inflammation.
Spot Treatments:
For some, acne can randomly appear in just one or two spots rather than a cluster or breakouts. Several ingredients and products can be applied directly to acne spots to reduce redness and inflammation, ultimately speeding up the healing process. Here are a few ingredients that Kopelman recommends for spot treatments:
Salicylic Acid: A beta hydroxy acid (BHA), which helps exfoliate the skin, reduce inflammation, and unclog pores
Benzoyl Peroxide: Kills acne-causing bacteria and reduces inflammation
Sulfur: Dries out active blemishes and reduces redness
Tea Tree Oil: Has antimicrobial properties, killing acne-causing bacteria. It also dries out the skin and reduces inflammation. (This is a good, natural option; however, Kopelman warns that it may irritate some people, so make sure to patch-test it first.)
HUM’s Skin Squad: Our unique formula that helps combat acne. This potent probiotic for clear skin contains 9 strains for non-cystic acne plus prebiotic konjac root for balanced gut health. It is a must-have supplement for your acne fight!
Pimple patches are another convenient option to use that contain many of the same (or similar) ingredients and are easy to apply, making them a favorite go-to for acne healing. “Spot treatments can be really effective,” she says, “but remember to use them sparingly—applying them to larger areas can dry out and irritate your skin.”
The Body Acne Mapping Takeaway
Understanding body acne mapping and how different parts of the body can be affected by specific factors is the key to treating and managing breakouts. The best way to achieve this is to be observant of where acne is showing up on your body and based on some of the potential factors, make small changes one by one. This will help you determine which lifestyle habits may be causing more harm than good. From here, you can take control and clear your skin from head to toe. This isn’t to say that you won’t get the occasional breakout from a sweaty workout or an ingrown from shaving, but with consistent changes, these occurrences should be minimal.
