You may be using the same cleanser or spot treatment on your face, chest and back, only to find that one area improves while another keeps breaking out. Perhaps your face has cleared, but painful spots still appear beneath your gym clothes or across areas that are difficult to reach.
Face and body acne develop through the same underlying process, so many of the same treatments can help. The difference is often in how those treatments are used. Facial skin may become irritated more easily, while treating the back or chest means covering a larger area and dealing with friction from clothing.
Why does acne appear on both the face and body?
Acne develops when hair follicles become blocked by excess oil and dead skin cells. Bacteria that normally live on the skin can then contribute to inflammation within the blocked follicle.
This can cause:
- Blackheads
- Whiteheads
- Inflamed red spots
- Pus filled spots
- Painful lumps or cysts
Hormones often play a part because they can increase oil production. This is why acne commonly begins during puberty, although it can continue into adulthood or appear for the first time later in life.
Family history, certain medicines, hormonal changes and some oily skin or hair products can also make acne more likely. Friction and pressure from tight clothing, sports equipment or backpacks may aggravate spots on the body.
Acne is not caused by dirty skin. Washing too often or scrubbing affected areas can damage the skin barrier and make irritation worse.
Does body acne require completely different treatment?
Usually not. The same types of treatment can often be used for acne on the face, chest, shoulders and back. What may change is the product format, how often it is applied and how much irritation the skin can tolerate.
A cream or gel may be practical for the face but difficult to spread across the back. A wash can be easier to use over a larger area. Your back may also tolerate a product differently from your face, so using the same treatment everywhere at the same frequency does not always work well.
The severity of the acne matters more than its location. Mild blackheads and small inflamed spots may respond to treatment from a pharmacy. Deep, painful lumps, widespread acne and spots that are causing scars are more likely to need prescription treatment.
What treatments can help facial acne?
A gentle routine is a sensible starting point. Wash your face twice a day with a mild cleanser and lukewarm water. Avoid scrubbing, picking or repeatedly changing products, as each of these can increase irritation.
Benzoyl peroxide can help some people with mild to moderate acne. It reduces acne associated bacteria and helps improve inflamed spots. It may also help reduce blackheads and whiteheads. A pharmacist can advise you about choosing and introducing an appropriate product.
Dryness, peeling, redness or stinging can occur, particularly when treatment is first started. Introducing it gradually and using a moisturiser labelled as suitable for acne prone skin may make it easier to tolerate. Very dry or tight skin does not mean the treatment is working better.
Prescription treatments may include topical retinoids, which help prevent follicles from becoming blocked. They are normally applied to the whole acne prone area rather than only to visible spots. Topical retinoids must not be used during pregnancy or when planning a pregnancy.
Whichever treatment you use, consistency matters. Acne treatments often take six to eight weeks to produce a noticeable improvement, and first line treatment is commonly reviewed after about 12 weeks.
How can acne on the back, chest and shoulders be treated?
Many of the same active treatments used for facial acne can help body acne. The challenge is applying them evenly and consistently across a larger area.
A benzoyl peroxide wash may be more convenient for the chest, back or shoulders than a cream or gel. Follow the product instructions and rinse it off thoroughly. Benzoyl peroxide can bleach clothing, towels and bedding, so take care when using it.
A few practical changes may also reduce irritation:
- Change out of damp exercise clothing when you can
- Wash clothing and towels that regularly touch affected skin
- Choose looser clothing if tight fabric rubs against the affected area
- Avoid oily or greasy products on acne prone skin
- Try not to pick or squeeze deeper spots
- Ask someone to help apply treatment to areas you cannot reach, if appropriate
Sweat itself does not cause acne. However, heat, moisture, friction and pressure against the skin can aggravate existing spots in some people.
Can I use the same acne product on my face and body?
Possibly, but you may need to use it differently on each area. A product that your back tolerates well may leave your face dry, sore or flaky. Equally, a gentle facial product may be difficult to apply over a large area of body acne.
Introduce one active treatment at a time and follow the product instructions. Combining several acne treatments without advice can lead to dryness, peeling and stinging. Once the skin becomes irritated, it can be harder to continue treatment consistently.
If you have been prescribed acne treatment, follow the instructions from your GP, pharmacist or dermatologist. Do not increase the amount or frequency because improvement feels slow. Using more than recommended is more likely to irritate your skin than clear the acne more quickly.
When should acne be checked by a doctor or dermatologist?
Speak to a GP if your acne is painful, widespread, causing scarring or persistent changes in skin colour, or has not improved after a suitable course of treatment. Deep lumps, nodules and cysts should be assessed because they have a greater chance of leaving scars.
It is also worth getting the diagnosis checked if spots on your body are particularly itchy, all look very similar or do not respond to acne treatment. Folliculitis and some other skin conditions can resemble body acne but may need a different approach.
A clinician may recommend prescription creams or gels, oral antibiotics used alongside topical treatment, or hormonal treatment for some women. Severe acne or acne that has not responded to appropriate treatment may require referral to a dermatologist. Isotretinoin may be considered in some of these cases, but it requires specialist assessment, monitoring and strict pregnancy prevention measures.
Acne can also affect confidence, mood and everyday life. If it is making you avoid exercise, certain clothes, relationships or social situations, that is a valid reason to seek help. Acne does not have to be medically severe before it deserves proper attention.
What matters most when treating acne in different areas?
Face and body acne usually respond to the same broad types of treatment. The routine may still need adjusting according to the area, the severity of the acne and how easily your skin becomes irritated.
For facial acne, protecting the skin from excessive dryness is particularly important. For the back, chest and shoulders, it also helps to consider friction, clothing and whether you can apply the treatment evenly.
Give an appropriate treatment enough time to work. If the acne is painful, persistent or beginning to scar, seek medical advice rather than continuing to experiment with stronger products.
