What is Fungal Acne?
Fungal acne, also known as Malassezia folliculitis or pityrosporum folliculitis, is a skin condition that is often mistaken for regular acne. However, unlike traditional acne, which is caused by bacteria and clogged pores, fungal acne results from an overgrowth of yeast in the hair follicles.
Malassezia is a type of yeast that naturally lives on your skin. When the balance of microorganisms is disrupted—due to factors like excessive sweating, humidity, or antibiotics—the yeast can grow out of control and cause infection and inflammation. This leads to small, itchy, uniform pimples, often appearing on the chest, back, and shoulders, though it can also affect the face.
Fungal acne is not technically acne, which is why typical acne treatments often don’t work. Correct diagnosis and targeted antifungal treatment are key.
Symptoms and Causes of Fungal Acne Infection
What Causes Fungal Acne?
Humidity and Sweat: Living in a hot, humid environment or sweating excessively (e.g., due to workouts) creates an ideal environment for yeast to thrive.
Tight or Non-Breathable Clothing: These can trap heat and moisture, further encouraging fungal growth.
Antibiotics: Long-term antibiotic use disrupts the skin's microbiome, eliminating bacteria that normally control yeast.
Weakened Immune System: Certain health conditions and medications can make you more susceptible.
Diet High in Sugars and Carbs: Yeast feeds on sugars, so an imbalanced diet can contribute.
Symptoms of Fungal Acne
Clusters of small, uniform red bumps
Itchiness (a key difference from bacterial acne)
Appears mostly on the forehead, chest, shoulders, and upper back
Often worsens in hot or humid environments
Does not respond to traditional acne treatments
How to Treat Fungal Acne
Over-the-Counter Antifungal Treatments
Antifungal Shampoos: Products containing ketoconazole, selenium sulfide, or zinc pyrithione can be used as body washes to help reduce yeast levels. Apply to affected areas and leave for 5–10 minutes before rinsing.
Topical Antifungal Creams: Look for clotrimazole or miconazole-based creams. Apply twice daily to the affected areas.
Prescription Medications
Oral Antifungals: In more persistent cases, dermatologists may prescribe fluconazole or itraconazole. These medications directly target internal yeast overgrowth.
Topical Prescription Treatments: Stronger topical antifungal agents may also be prescribed for severe or resistant cases.

Lifestyle and Skincare Tips to Prevent Fungal Acne
Skincare Routine Adjustments
Avoid Oily Products: Malassezia yeast feeds on lipids. Switch to oil-free or non-comedogenic products.
Use Antifungal Body Washes Regularly: Especially after workouts or on humid days
Exfoliate Gently: Regular exfoliation can help unclog follicles, but avoid harsh scrubs that can worsen inflammation.
Lifestyle Modifications
Shower After Sweating: Don’t let sweat sit on your skin. Change out of damp clothes promptly.
Wear Breathable Fabrics: Opt for cotton and moisture-wicking materials.
Eat a Balanced Diet: Limit sugar and refined carbohydrates.
Change Bedding Frequently: Yeast and sweat accumulate on sheets and pillowcases.
Medical Conditions That Cause Acne
It's also important to note that fungal acne may sometimes be confused with acne caused by underlying health issues. For example, hormonal imbalances, insulin resistance, or autoimmune conditions can all trigger acne-like symptoms. For a more comprehensive understanding, read about medical conditions that cause acne.
If you’re uncertain about the cause of your breakouts, a consultation with a skincare specialist is essential. Getting the right diagnosis ensures you’re not using the wrong products that may worsen your condition.
When to See a Professional
If you've tried multiple over-the-counter acne treatments without success, or if your condition worsens with traditional skincare products, it may be time to consult a dermatologist. Persistent itching, spreading of the condition, or signs of infection (like pus or pain) warrant professional evaluation and possible prescription medications.
