What works for fungal acne?
Established. Cheap to treat, easy to miss, and likely to come back in the heat. A 2023 European position statement sets diagnostic features — monomorphic itchy papulopustules, lack of comedones, failure of acne therapy — and recommends topical antifungals first and oral antifungals for extensive disease.
- Verdict

- Suits
- Itchy, uniform small bumps on the chest, back or shoulders that have not responded to acne treatment, especially after sweating or antibiotics — confirmed by a doctor, treated with antifungal washes first.
- Not for

What it is
Malassezia folliculitis is an infection of hair follicles by Malassezia yeast, which lives normally on skin and overgrows in heat, humidity, sweat and after antibiotics. It causes small, uniform, itchy bumps and pustules on the chest, back, shoulders and sometimes the forehead and jaw. It is not acne, and acne antibiotics can make it worse.
How it works
Antifungal shampoos and washes (ketoconazole, selenium sulfide) used as a body wash and left on for a few minutes, topical antifungal creams, and for extensive or stubborn cases a short course of oral antifungal tablets prescribed by a doctor. Recurrence is common in hot weather, so weekly maintenance washes are usual.
What the evidence says
A 2023 European position statement sets diagnostic features — monomorphic itchy papulopustules, lack of comedones, failure of acne therapy — and recommends topical antifungals first and oral antifungals for extensive disease. A 2026 review in the Journal of Drugs in Dermatology confirms good response to antifungals and highlights frequent coexistence with true acne, which is why diagnosis by a doctor matters.

What the studies show
- guideline
Diagnosis rests on clinical features, microscopy where available, and response to antifungals; topical antifungals are first line and oral azoles for extensive or recurrent disease.
Position statement: Recommendations on the diagnosis and treatment of Malassezia folliculitis. — J Eur Acad Dermatol Venereol, 2023. PMID 36912427.
- review
Malassezia folliculitis is common, often coexists with acne vulgaris and responds well to topical and oral antifungals, with maintenance needed to prevent recurrence.

Comedonal or cystic acne, which needs acne treatment; anyone self-treating with long antifungal courses without a diagnosis.
Alternatives
The two reviewed treatments most often weighed against Fungal acne (Malassezia folliculitis), on the same standard.
| Fungal acne (Malassezia folliculitis) | Isotretinoin for acne | Oral antibiotics for acne | |
|---|---|---|---|
| Verdict | Established | Established | Established |
| What it is | Malassezia folliculitis is an infection of hair follicles by Malassezia yeast, which lives normally on skin and overgrows in heat, humidity, sweat and after antibiotics. | Isotretinoin is an oral retinoid, a vitamin A derivative, prescribed for severe or scarring acne and for moderate acne that has not responded to other treatment. | Tetracycline-class antibiotics — doxycycline, minocycline, lymecycline and the newer narrow-spectrum sarecycline — taken by mouth for moderate to severe inflammatory acne. |
| Evidence base | 2 PubMed-indexed studies cited below, including guidelines. | 4 PubMed-indexed studies cited below, including systematic reviews, meta-analyses, randomised trials. | 4 PubMed-indexed studies cited below, including meta-analyses, randomised trials, guidelines. |
| Suits | Itchy, uniform small bumps on the chest, back or shoulders that have not responded to acne treatment, especially after sweating or antibiotics — confirmed by a doctor, treated with antifungal washes first. | Severe, nodular or scarring acne; moderate acne that has failed topicals and oral antibiotics; adults with persistent acne who accept monitoring and, for women, strict contraception. | Moderate to severe inflammatory acne — red papules and pustules on the face, chest or back — as a time-limited course alongside a topical retinoid or benzoyl peroxide, prescribed and reviewed by a doctor. |
| In one line | Cheap to treat, easy to miss, and likely to come back in the heat. | The side effects are real and mostly manageable; the pregnancy rule is absolute. | Three months with a retinoid alongside is the job; if acne returns each time it stops, the next conversation is isotretinoin or, for women, spironolactone. |
Risks
Dryness and irritation from antifungal washes; oral antifungals can interact with other medicines and affect the liver, which is why they are prescribed; recurrence when maintenance stops.
In Singapore
Malassezia folliculitis is common in Singapore's climate. Antifungal shampoos are available in pharmacies; oral antifungals need a prescription. A doctor can distinguish it from acne, and treat both when they coexist.
