Back acne (or “bacne”) is one of the most common yet ignored skin concerns. Just like facial acne, it can range from mild congestion to painful cystic breakouts and it can be just as stubborn. Even worse, the location often makes it hard to treat properly or monitor response. Despite all this, there’s some good news. There are highly effective ways to treat and prevent back acne. In this article, we’re going to explore the underlying causes of back acne and how to prevent it. We’ll also review the best products and treatments to get rid of back acne.
What is Back Acne and What Causes It?
This is a blanket term. It usually refers to pimples that develop on your back, shoulders and sometimes even the upper arms. Like on the face, back acne usually occurs due to a combination of clogged pores, excess oil (sebum), inflammation and sometimes bacteria. Although back acne is very common in teens, adults can also struggle with it. Regardless of age, back acne can be harder to manage. This is because of its location and the thicker skin on this part of the body.
Understanding the cause of back acne is key to choosing the right treatment and prevention strategy. However, there isn’t usually a single cause for developing acne on your back. It’s often due to a combination of factors and the most common causes include:
- Overactive oil glands: When your skin makes too much oil, it can mix with dead skin cells and clog pores. Furthermore, acne-forming bacteria on the skin (P. acnes) thrive in this environment of clogged pores and excess sebum. This triggers inflammation and acne.
- Sweat and friction (acne mechanica): This is a type of acne that occurs due to tight clothing, sports gear or backpacks. These can trap sweat and irritate the skin to trigger breakouts.
- Hormones: Just like with facial acne, excess androgen levels or increased activity of these hormones on the skin can increase oil production. This leads to breakouts and is common during puberty, menopause and with medications like progesterone-only contraceptives.
- Lifestyle: Not washing after sweating, using comedogenic products or skipping exfoliation can all worsen back acne.
- Genetics: If you have a family history of acne or currently suffer from facial breakouts, you might be more prone to back acne.
- Health: Conditions like polycystic ovary syndrome (PCOS), thyroid problems and excess cortisol production can all trigger back acne.
What Are the Types of Back Acne?
Back acne can present in several different forms. It’s important to try and figure out which type or types you have. This can help determine the best treatment to help get rid of back acne. In general, the main types of acne on the back are:
- Comedonal acne: This typically presents as blackheads and whiteheads which are due to clogged pores. This type of acne is typically non-inflammatory but can progress if you don’t treat it. Comedonal acne usually responds well to exfoliants like salicylic acid or glycolic acid which help keep pores clear. Retinoids can also be helpful in preventing future acne.
- Papules and pustules: These are red swollen bumps (papules) and pus-filled spots (pustules). They signal infection and inflammation within the pores. This form of inflammatory acne usually benefits from a combination of anti-inflammatory and antibacterial ingredients such as benzoyl peroxide, niacinamide and azelaic acid. If it persists, prescription antibiotics or retinoids may be necessary.
- Nodules and cysts: These are larger, deeper and often painful breakouts that can lead to scarring. They often require prescription treatments such as antibiotics, hormone targeting therapy or oral isotretinoin. In-clinic procedures like chemical peels or laser may help support long-term management.
- Acne mechanica: This type of acne breakout is often due to tight clothing, sports equipment or backpacks. It often improves with lifestyle changes (e.g. breathable clothing and showering after exercise) as well as gentle exfoliation.
What Are the Best Skincare Products for Back Acne?
Unless your acne is severe or painful, over-the-counter treatments are a great starting point for most people. These products are generally easy to access. They can also be highly effective for getting rid of mild to moderate back acne when used consistently. The best ingredients to look for when choosing skincare products for back acne include:
- Beta hydroxy acids (BHAs): Salicylic acid and other BHAs are exfoliants that help dissolve oil and dead skin inside pores. This helps unclog pores and is ideal for blackheads and whiteheads. It can also help prevent development of inflammatory acne lesions like papules and pustules. BHAs can also help improve skin texture and fade post-inflammatory hyperpigmentation.
- Benzoyl peroxide: This is a powerful antibacterial agent that kills the bacteria involved in acne formation and helps reduce inflammation. It’s particularly effective for mild to moderate inflammatory lesions like papules and pustules. Benzoyl peroxide can also help prevent them from progressing to cystic acne when used regularly.
- Niacinamide: A multi-tasking antioxidant, niacinamide calms inflammation and supports the skin barrier. It’s suitable for all types of back acne but particularly beneficial for mild inflammatory lesions.
- Sulphur: A natural mineral with keratolytic properties, sulphur helps to dry out superficial acne by absorbing excess oil and gently exfoliating dead skin cells. It also has mild antibacterial effects, making it effective for managing mild inflammatory acne and to prevent clogged pores.
- Zinc: This trace element has soothing, anti-inflammatory properties that can calm redness and irritation. It also helps to regulate oil production. You can commonly find Zinc in both topical treatments and supplements for acne-prone skin. It’s especially helpful for sensitive or reactive skin types with inflammatory back acne.
- Azelaic acid: A gentle but effective anti-inflammatory and antibacterial agent, azelaic acid also helps prevent blocked pores and fades dark marks from old spots. It works well for all skin types and is especially useful for those with sensitive skin or for treating acne alongside post-inflammatory hyperpigmentation.
- Retinol: This over-the-counter form of vitamin A increases cell turnover, prevents clogged pores and supports collagen production. While not as potent as prescription retinoids, it’s still effective for treating comedonal acne and improving overall skin texture as well as evening out tone.
What Prescription and Professional Treatments Help?
If your back acne is cystic, painful or not responding to over-the-counter treatments, it might be time to seek help. A doctor or other medical provider can advise you. They can carefully assess your skin. Where appropriate, they can provide prescription or in-office treatments that help get rid of your back acne.
Prescription treatments can help address some of the underlying causes and provide more comprehensive treatment for moderate to severe back acne. Some of the most widely used prescription treatments for back acne include:
- Topical retinoids: These vitamin A derivatives help unclog pores and promote skin turnover. The most commonly used prescription topical retinoids for back acne include adapalene, tretinoin and tazarotene. They can help with all types of acne.
- Topical antibiotics: This includes drugs like clindamycin which reduce acne-causing bacteria and inflammation directly at the site of breakouts. They’re commonly prescribed with benzoyl peroxide or retinoids to prevent antibiotic resistance. Topical antibiotics are best for moderate inflammatory back acne.
- Oral antibiotics: These are for short term use when there’s widespread or painful acne on the back and include drugs like doxycycline. They work to reduce bacteria and inflammation but are typically combined with topical treatments to support long-term maintenance.
- Hormonal therapy: Treatments like the combined oral contraceptive pill or anti-androgens (e.g. spironolactone) regulate hormones that trigger excess oil production. They’re especially effective for cyclical or hormone driven back acne in women.
- Oral isotretinoin (Roaccutane): This is a powerful form of vitamin A that targets all the major causes of acne including excess oil, clogged pores, inflammation and bacteria. Due to potential side effects, Roaccutane is reserved for severe, cystic or stubborn acne that is not responding to other treatments. It is can only be prescribed by a dermatologist and requires close medical supervision including blood tests throughout treatment.
Professional clinic procedures can also be a useful addition. This is especially true if your back acne is stubborn or if there is scarring or hyperpigmentation. Whilst there are a lot of treatments available, there isn’t adequate scientific evidence for most of them. In fact, very few if any can get rid of back acne on their own. As such, they’re best used as part of a multi-treatment approach. This means a lot of background reading and expectation setting is needed. Some of the most effective professional treatments for back acne include:
- Chemical peels: Professional peels like Jessner’s, salicylic or glycolic acid can help deeply exfoliate the skin, unclog pores and reduce active breakouts. They can also help fade post-acne dark marks and improve skin texture over time.
- Light therapy: Whilst more data is required, there’s evidence that specific wavelengths of blue and red light can help to kill acne-causing bacteria and calm inflammation. This can help reduce active lesions and support healing.
- Microneedling: This procedure uses fine needles to create controlled micro-injuries in the skin, stimulating collagen production and promoting renewal. Whilst it can’t treat acne, microneedling is helpful for back acne scarring and uneven texture.
- Laser: These target the deeper layers of skin to reduce oil gland activity, control inflammation and improve post-acne scarring or hyperpigmentation. Fractional and non-ablative lasers are commonly used on the back to enhance clarity and skin tone with minimal recovery time.
- Surgery and extraction: In cases of large, painful cysts or nodules, surgical drainage or excision may be necessary to remove the lesion and prevent further inflammation or scarring. Dermatological extraction can also help clear stubborn comedones or closed lesions. These interventions are usually only used for treatment resistant or severe back acne when other treatments and products have failed.
How Do You Prevent and Get Rid of Back Acne?
Preventing future breakouts involves a combination of good skincare, healthy habits and avoiding common triggers. Regardless of whether you have prescription or professional treatments, tackling back acne effectively requires a consistent skincare routine. This, alongside a few lifestyle measures, will help you maximise your chances of getting rid of back acne. It also helps you maintain your results. Here are our top tips for tackling and preventing back acne:
- Gently cleanse skin daily: Use a gentle but effective cleanser to remove oil, sweat and debris from the skin. It’s especially important to shower soon after working out or sweating. Avoid harsh scrubbing as this can worsen inflammation and disrupt the skin barrier.
- Exfoliate regularly: Chemical exfoliants like salicylic acid, azelaic acid or enzymes can help unclog pores and prevent breakouts. They can also help improve skin texture and even out skin tone. Use them up to 2 to 3 times a week depending on your skin’s tolerance.
- Actively treat breakouts: Leave-on products with acne-fighting ingredients such as niacinamide, benzoyl peroxide or retinoids work well here. They reduce inflammation, kill bacteria and prevent new spots from forming. Look for formulations that are designed for body application or come in spray formats to make applying on your back acne easier.
- Wear breathable loose clothing: Minimise friction by avoiding tight straps, heavy backpacks or synthetic materials that trap sweat. This simple switch can reduce irritation and prevent flare-ups. Also change and wash clothes regularly (particularly bras and gym wear).
- Introduce skincare products gradually: This will help reduce the risk of purging, irritation or sensitising your skin.
Whilst frustrating, back acne is a highly treatable skin condition with the right approach. From over-the-counter skincare products to prescription and professional treatments, there’s a range of options to help get rid of back acne. The best treatment will depend on your skin concerns, triggers and goals. You’ll also need to be patient and consistent. If your back acne is stubborn or severe, try to seek medical help early. This ensures you have access to the most appropriate treatment options. Just remember acne, including on the back, is often a chronic condition. So alongside getting rid of back acne, your treatment should also focus on maintenance and prevention.
