You have been washing your face religiously, applying your benzoyl peroxide, maybe even trying prescription acne treatments — and nothing is working. The small, itchy bumps on your forehead, chest, or back just keep coming back. If this sounds familiar, there is a real possibility that what you are dealing with is not actually acne at all.

Fungal acne — medically known as Malassezia folliculitis or Pityrosporum folliculitis — is a condition caused by an overgrowth of yeast in the hair follicles. It is frequently mistaken for traditional acne vulgaris because the two conditions can look remarkably similar to the untrained eye. But the treatment is completely different. In fact, some common acne treatments like antibiotics can actually make fungal acne worse by disrupting the skin's natural microbial balance and allowing yeast to thrive.

Understanding the difference matters. If you have been struggling with bumps that will not respond to conventional acne care, this guide will help you figure out whether fungal acne might be the culprit — and, more importantly, how to get rid of it.

Quick Answer: How to Get Rid of Fungal Acne

What it is: Fungal acne is caused by Malassezia yeast overgrowth in hair follicles — not bacteria. It requires antifungal treatment, not standard acne products.

Key treatments:

  • Over-the-counter: Ketoconazole shampoo (used as a body/face wash), zinc pyrithione soap, selenium sulfide shampoo
  • Prescription: Oral fluconazole or itraconazole for stubborn or widespread cases
  • Maintenance: Antifungal wash 1-2 times per week after clearing to prevent recurrence

Key point: If your "acne" is itchy, consists of uniform small bumps, and does not respond to regular acne treatments, see a dermatologist to rule out fungal acne.

What Is Fungal Acne?

Despite its name, fungal acne is not actually acne. True acne vulgaris is caused by Cutibacterium acnes bacteria clogging pores and triggering inflammation. Fungal acne, on the other hand, is an infection of the hair follicles caused by Malassezia — a genus of yeast that naturally lives on everyone's skin.

Under normal circumstances, Malassezia yeast exists in balance with bacteria and other microorganisms on your skin's surface. But when conditions shift — whether due to excess moisture, heat, a weakened immune system, or antibiotic use — this yeast can overgrow and infiltrate hair follicles. The result is inflammation that produces clusters of small, uniform bumps that closely resemble acne.

The medical term for this condition is Malassezia folliculitis (sometimes still referred to as Pityrosporum folliculitis). A study published in the Journal of Clinical and Aesthetic Dermatology found that Malassezia folliculitis is commonly misdiagnosed as acne vulgaris, leading to prolonged ineffective treatment and patient frustration. Research in the Indian Dermatology Online Journal notes that the condition may account for a significant portion of treatment-resistant "acne" cases, particularly in hot, humid climates.

What to expect: Because Malassezia yeast is a normal part of the skin microbiome, fungal acne is not about having "dirty" skin. It is about an imbalance. Once you understand this, the treatment approach — restoring balance and controlling yeast overgrowth — makes much more sense.

Fungal Acne vs. Regular Acne: How to Tell the Difference

One of the biggest challenges with fungal acne is that it looks a lot like regular acne at first glance. But there are several key differences that can help you — and your dermatologist — tell them apart. Learning the origins of your acne is an important first step toward effective treatment.

Feature Fungal Acne (Malassezia Folliculitis) Regular Acne (Acne Vulgaris)
Appearance Uniform, small (1-2 mm) papules and pustules that all look roughly the same size Varied — mix of blackheads, whiteheads, papules, pustules, nodules, and cysts of different sizes
Itching Often very itchy Usually not itchy (may be tender or painful)
Location Forehead, chest, upper back, shoulders — areas prone to sweating Face (especially T-zone, chin, jawline), back, chest
Comedones No blackheads or whiteheads Blackheads and whiteheads are common
Cause Malassezia yeast overgrowth Cutibacterium acnes bacteria, excess sebum, clogged pores
Response to antibiotics Gets worse or does not improve Typically improves
Triggers Heat, humidity, sweating, antibiotics, occlusive products Hormones, stress, pore-clogging products, bacteria

The single most telling clue is uniformity. If your bumps all look the same — small, dome-shaped, and clustered — that is a hallmark of fungal acne. Regular acne almost always presents with a variety of lesion types and sizes.

How to Know If You Have Fungal Acne

While only a dermatologist can provide a definitive diagnosis, there are several signs that your breakouts may be fungal rather than bacterial.

Your Bumps Are Uniform in Size and Shape

This is the number one distinguishing feature. Fungal acne produces clusters of small papules and pustules that are all roughly 1-2 mm in diameter. They tend to appear in groups rather than as scattered, isolated blemishes. If you look at your breakouts and they all look like near-identical bumps, fungal acne should be on your radar.

They Itch — Sometimes Intensely

Regular acne can be tender or painful, but it is rarely itchy. Fungal acne, on the other hand, often comes with noticeable itching or a prickling sensation, especially when you sweat. According to a review in the Indian Dermatology Online Journal, pruritus (itching) is one of the most consistent symptoms reported by patients with Malassezia folliculitis.

They Appear on Your Chest, Back, or Forehead

Fungal acne tends to concentrate in areas with a high density of sebaceous glands and where sweat accumulates — the chest, upper back, shoulders, and forehead. While regular acne can appear in these areas too, fungal acne is particularly common on the trunk and forehead, sometimes sparing the cheeks and jawline entirely.

Standard Acne Treatments Are Not Working

If you have been using benzoyl peroxide, salicylic acid, topical retinoids, or even oral antibiotics for weeks or months without improvement — or if your condition has worsened while on antibiotics — that is a strong signal. Antibiotics can reduce the bacterial population on the skin, which may actually allow Malassezia yeast to proliferate unchecked.

Breakouts Flare After Sweating or in Humid Conditions

Malassezia thrives in warm, moist environments. If you notice that your bumps consistently worsen after exercise, during summer months, or when you travel to humid climates, fungal acne is a likely explanation.

Important: It is possible to have both fungal acne and regular acne at the same time. This is one reason why self-diagnosis can be tricky. If you are unsure, a dermatologist can perform a simple skin scraping or Wood's lamp examination to confirm whether Malassezia yeast is involved. Getting the right diagnosis is essential because the treatments are fundamentally different.

What Causes Fungal Acne?

Since Malassezia yeast is naturally present on everyone's skin, fungal acne is really about what triggers overgrowth. Several factors can tip the balance.

Heat and Humidity

Malassezia is a lipophilic (fat-loving) yeast that thrives in warm, humid environments. This is why fungal acne is significantly more common in tropical and subtropical climates. A review published in the Journal of Fungi notes that Malassezia species proliferate more rapidly at elevated temperatures and humidity levels, which explains seasonal flares during summer.

Excessive Sweating

Sweat itself does not cause fungal acne, but sitting in sweaty clothing creates the perfect environment for yeast overgrowth. The combination of moisture, warmth, and occlusion (tight clothing trapping sweat against the skin) is a recipe for Malassezia folliculitis. This is why the condition is especially common in athletes and people who work in hot environments.

Antibiotic Use

This is one of the most important and overlooked triggers. Oral antibiotics — including doxycycline and minocycline, commonly prescribed for acne — can kill off the bacteria that normally keep Malassezia in check. With bacterial competition reduced, yeast populations can expand rapidly. Research in the Indian Dermatology Online Journal highlights antibiotic use as a well-established risk factor for developing Malassezia folliculitis.

Occlusive Skincare Products and Oils

Malassezia feeds on specific fatty acids, particularly those with carbon chain lengths of 11-24. Many common skincare oils and occlusive products contain these fatty acids, effectively providing fuel for yeast overgrowth. Products like coconut oil, olive oil, and heavy moisturizers can worsen fungal acne even though they might be perfectly fine for bacterial acne.

Immunosuppression

People with weakened immune systems — whether from conditions like HIV/AIDS, diabetes, or from immunosuppressive medications — are at higher risk for Malassezia folliculitis. The immune system normally keeps yeast populations in check, and when it is compromised, overgrowth becomes more likely.

Tight, Non-Breathable Clothing

Synthetic fabrics and tight clothing create an occlusive environment that traps heat and moisture against the skin. This is particularly problematic for the chest and back, where fungal acne most commonly occurs.

Is Fungal Acne Contagious?

No, fungal acne is not contagious. You cannot catch it from someone else or spread it through skin-to-skin contact, sharing towels, or any other form of contact.

This is because Malassezia yeast already lives on virtually everyone's skin. It is part of the normal skin microbiome. Fungal acne develops when conditions on your skin allow this yeast to overgrow — it is not about being exposed to a foreign organism. Research published in the Journal of Fungi confirms that Malassezia species are commensal organisms found on the skin of all humans, and that disease occurs due to a shift from commensal to pathogenic behavior rather than from external transmission.

So you do not need to worry about going to the gym, sharing equipment, or being close to others. Your fungal acne is about your skin's individual environment, not exposure.

How to Treat Fungal Acne

The good news is that once you have the right diagnosis, fungal acne responds well to treatment. The approach centers on antifungal agents — not the antibacterial products you would use for regular acne.

Over-the-Counter Antifungal Treatments

Many effective antifungal treatments for Malassezia folliculitis are available without a prescription. These work by directly targeting the yeast responsible for the condition.

Ketoconazole shampoo (2%): This is often the first-line recommendation. Although it is sold as a dandruff shampoo (since dandruff is also caused by Malassezia), ketoconazole shampoo can be used as a face and body wash for fungal acne. Apply it to affected areas, leave it on for 3-5 minutes, then rinse. A study in the British Journal of Dermatology found that ketoconazole was effective in treating Pityrosporum folliculitis, with most patients showing significant improvement within 2-4 weeks.

Zinc pyrithione soap or wash (2%): Zinc pyrithione has both antifungal and antibacterial properties. It is available in bar soap and body wash formulations and can be used daily. It is generally well-tolerated and can be particularly useful for maintenance after the initial flare has been controlled.

Selenium sulfide shampoo (1-2.5%): Another dandruff shampoo ingredient that doubles as a fungal acne treatment. Apply to affected skin, leave on for 5-10 minutes before rinsing, and use several times per week.

Topical clotrimazole or miconazole cream: These over-the-counter antifungal creams, commonly sold for athlete's foot, can also be applied to areas of fungal acne. They are best used for small, localized patches.

What to expect: Most people start seeing improvement within 1-3 weeks of consistent antifungal treatment. The itching usually resolves first, followed by a gradual reduction in the number of bumps. Full clearance may take 4-6 weeks. If you do not see improvement after 3-4 weeks, see a dermatologist — you may need prescription-strength treatment, or the diagnosis may need to be reconsidered.

Prescription Treatments

When over-the-counter antifungals are not enough — particularly for widespread or recurrent cases — a dermatologist may prescribe oral antifungal medications.

Oral fluconazole: A systemic antifungal that targets Malassezia from the inside. It is typically prescribed as a short course (such as 100-200 mg daily for 2-4 weeks). Research published in Mycoses has demonstrated the efficacy of oral fluconazole in treating Malassezia folliculitis, with high clearance rates and generally good tolerability.

Oral itraconazole: Another systemic antifungal option, often used as a pulse therapy (such as 200 mg daily for one week per month). It is particularly useful for patients with recurrent episodes.

Prescription-strength ketoconazole cream (2%): For cases where a stronger topical approach is needed, a dermatologist can prescribe ketoconazole cream for direct application to affected areas.

Treatment Comparison at a Glance

Treatment Type Best For Prescription?
Ketoconazole shampoo (2%) Topical antifungal wash First-line treatment for most cases No (OTC available)
Zinc pyrithione soap (2%) Antifungal/antibacterial wash Daily use and maintenance No
Selenium sulfide shampoo Antifungal wash Alternative to ketoconazole No (1%); Rx (2.5%)
Clotrimazole/miconazole cream Topical antifungal cream Small, localized patches No
Oral fluconazole Systemic antifungal Widespread or resistant cases Yes
Oral itraconazole Systemic antifungal Recurrent cases, pulse therapy Yes

What to Avoid If You Have Fungal Acne

Knowing what not to do is just as important as knowing what to do. Many common skincare habits and products can feed Malassezia yeast or create conditions that worsen fungal acne.

Oils That Feed Malassezia

Malassezia yeast feeds on specific fatty acids, particularly those with carbon chain lengths between C11 and C24. Many popular skincare oils are rich in these fatty acids and should be avoided if you have fungal acne.

Oils to avoid:

  • Coconut oil
  • Olive oil
  • Jojoba oil (despite being commonly recommended for acne-prone skin)
  • Sweet almond oil
  • Argan oil
  • Marula oil
  • Most plant-based facial oils

Safer alternatives: Mineral oil and squalane oil are generally considered safe for fungal acne-prone skin because Malassezia cannot metabolize them. However, if you want to be cautious, oil-free moisturizers and products are the safest bet.

Heavy, Occlusive Moisturizers

Thick creams and ointments that create an occlusive barrier on the skin can trap moisture and heat, promoting yeast growth. Opt for lightweight, oil-free gels or lotions instead. Look for "non-comedogenic" and "oil-free" on labels, and check ingredient lists for the oils mentioned above.

Standard Acne Treatments (Used Alone)

Benzoyl peroxide and salicylic acid target bacteria and pore blockages, neither of which is the primary issue in fungal acne. While benzoyl peroxide is not harmful and may offer some mild benefit due to its drying properties, it should not be your primary treatment. Salicylic acid can help with the skin texture but will not address the underlying yeast overgrowth.

Oral Antibiotics (Without Antifungals)

If you are on antibiotics for what was diagnosed as acne and your condition is actually fungal, the antibiotics may be making things worse. Do not stop any medication without consulting your provider, but do discuss the possibility of fungal acne with your dermatologist if your condition is not improving.

Red flag: If your breakouts worsened after starting an antibiotic for acne, tell your dermatologist. This is a classic sign that fungal acne may be involved. Antibiotics reduce the bacteria that compete with Malassezia, potentially allowing the yeast to thrive.

How to Prevent Fungal Acne

Fungal acne has a tendency to recur, especially during warmer months or when conditions favor yeast overgrowth. These prevention strategies can help you stay clear.

Fungal Acne Prevention Checklist

  • Shower and change out of sweaty clothing immediately after exercise
  • Use a ketoconazole or zinc pyrithione wash 1-2 times per week as maintenance
  • Wear loose, breathable fabrics — especially during workouts and in warm weather
  • Choose oil-free, fungal acne-safe skincare products
  • Avoid heavy, occlusive moisturizers on prone areas
  • Change pillowcases and sheets regularly (at least weekly)
  • If you are prescribed antibiotics, discuss antifungal prevention with your dermatologist
  • Keep skin clean and dry in hot, humid conditions

Maintenance is key with fungal acne. Even after your skin clears, continuing to use an antifungal wash once or twice a week can prevent the yeast from overgrowing again. Think of it like dandruff — you manage it, you do not cure it, because the yeast is always present on the skin.

Building a Fungal Acne-Safe Skincare Routine

If you have fungal acne, you may need to rethink your entire skincare routine — not just your acne treatment. The goal is to avoid feeding Malassezia while keeping your skin healthy and hydrated.

Cleanser

Use a gentle, oil-free cleanser for daily washing. On treatment days (2-3 times per week, or daily during active flares), use a ketoconazole or zinc pyrithione wash on affected areas. Leave the antifungal wash on for 3-5 minutes before rinsing for maximum effectiveness.

Moisturizer

Choose a lightweight, oil-free moisturizer or gel. Look for products that rely on glycerin, hyaluronic acid, or ceramides for hydration rather than plant oils. These ingredients are not a food source for Malassezia.

Sunscreen

Use a mineral (zinc oxide or titanium dioxide) sunscreen rather than a chemical sunscreen. Many chemical sunscreens contain fatty acid esters that can feed Malassezia. Mineral options sit on top of the skin and are generally safer for fungal acne-prone skin.

Actives

Some traditional acne actives can still play a role in a fungal acne routine. Tretinoin (a topical retinoid) can help with skin cell turnover and improving post-inflammatory marks, and it does not worsen fungal acne. Azelaic acid is another good option — it has mild antifungal properties in addition to its anti-inflammatory and brightening effects.

What to expect: Switching to a fungal acne-safe routine can feel restrictive at first, especially if you are used to oil-based cleansers or rich moisturizers. But most people find that their skin adjusts quickly, and the improvement in their breakouts makes it well worth the effort. Our dermatologists can help you build a personalized skincare routine that is safe for fungal acne-prone skin.

When to See a Dermatologist for Fungal Acne

While mild cases of fungal acne can sometimes be managed with over-the-counter antifungal washes, there are several situations where seeing a dermatologist is the right move.

See a dermatologist if:

  • You are not sure whether your bumps are fungal acne or regular acne
  • Over-the-counter antifungal treatments have not improved your condition after 3-4 weeks
  • Your fungal acne keeps coming back despite maintenance treatment
  • The affected area is widespread (covering large areas of your chest, back, or face)
  • You are also dealing with regular acne and need a treatment plan that addresses both
  • Your breakouts worsened after starting antibiotics

Getting an accurate diagnosis is the most important step. A dermatologist can perform a skin scraping, examine your skin under a Wood's lamp (which can cause Malassezia to fluoresce), or even take a biopsy in unclear cases. Once the diagnosis is confirmed, they can prescribe oral antifungals if needed and help you develop a comprehensive plan to both clear the current flare and prevent future ones.

At Honeydew, our board-certified dermatologists, nurse practitioners, and physician assistants see many patients who have been struggling with treatment-resistant "acne" that turns out to be fungal. We offer same-day or next-day video appointments, so you do not have to wait weeks to get answers. During your consultation, your provider will review your skin, discuss your symptoms and treatment history, and determine whether antifungal treatment is needed. If you have both fungal and bacterial acne, we can create a treatment plan that addresses both conditions simultaneously.
