Fungal acne causes, symptoms, and treatment

Fungal acne (Malassezia folliculitis), also known as pityrosporum folliculitis, is a common skin condition that is often mistaken for traditional acne. Unlike bacterial acne, which is caused by the proliferation of Propionibacterium acnes bacteria, fungal acne is triggered by an overgrowth of yeast called Malassezia. In this article, we will delve into the causes, symptoms, and treatment options for fungal acne. By understanding this condition, you can effectively differentiate it from bacterial acne and seek appropriate remedies to address the underlying fungal infection.

Fungal Acne Causes and Symptoms

Fungal acne occurs when the yeast Malassezia, which is normally present on the skin, multiplies excessively and invades the hair follicles. Several factors can contribute to the development including:

  • Humid environments: Warm and moist conditions create an ideal breeding ground for Malassezia, leading to its overgrowth and subsequent formation of Malassezia folliculitis.
  • Occlusive clothing and skincare products: Tight-fitting clothes and heavy, occlusive skincare products can trap sweat and moisture, providing an environment conducive to fungal growth.
  • Weakened immune system: Individuals with compromised immune systems, such as those with autoimmune conditions or HIV/AIDS, may be more susceptible to fungal infections, including Malassezia folliculitis.

Malassezia folliculitis typically presents as small, uniform, itchy, or tender bumps that resemble traditional acne. However, there are several distinguishing features that can help differentiate fungal acne from bacterial acne. These include:

  • Lack of whiteheads or blackheads: Fungal acne lesions typically lack the characteristic whiteheads or blackheads seen in bacterial acne. Instead, they appear as small, red, or flesh-colored bumps.
  • Uniformity: Fungal acne lesions tend to appear in clusters or lines and are often evenly distributed, as opposed to the random and scattered pattern of bacterial acne.
  • Persistence: Fungal acne lesions may persist for weeks or even months, as they are caused by an ongoing fungal infection.

Diagnosing Fungal Acne

Proper diagnosis is crucial to effectively treat fungal acne. Dermatologists can perform various diagnostic techniques, including:

  • Visual examination: Dermatologists examine the appearance and distribution of the skin lesions to differentiate between fungal acne and bacterial acne.
  • Skin scraping or culture: In some cases, dermatologists may collect a sample of skin cells or discharge for laboratory analysis to confirm the presence of Malassezia yeast.

Fungal Acne Treatment Options

The treatment of fungal acne on face typically involves a multi-pronged approach aimed at eliminating the fungal overgrowth and preventing its recurrence. Treatment options include:

  • Topical antifungal agents: Prescription-strength topical antifungal medications, such as ketoconazole or ciclopirox, are often used to eradicate the Malassezia yeast. These medications may be applied once or twice daily for several weeks until the infection clears.
  • Antifungal cleansers: Specialized cleansers containing ingredients like ketoconazole or selenium sulfide can help reduce the fungal load on the skin. These cleansers are typically used in conjunction with topical antifungal agents.
  • Adjusting skincare routine: Avoiding heavy, oil-based products and opting for non-comedogenic and oil-free skincare products can help prevent the buildup of sweat and sebum that contribute to Malassezia folliculitis.
  • Hygiene practices: Maintaining good hygiene practices, such as showering regularly, using clean towels and clothing, and avoiding sharing personal items, can help prevent the spread and recurrence of fungal acne.
  • Lifestyle modifications: Making certain lifestyle changes, such as wearing loose-fitting clothing and avoiding excessive sweating, can help create an environment less conducive to fungal growth.

Prevention and Management of Fungal Acne

Preventing fungal acne involves adopting certain practices and habits to minimize the risk of fungal overgrowth. These include:

  • Keeping the skin clean and dry: Regularly cleansing the skin with a mild, non-comedogenic cleanser and ensuring it is thoroughly dry can help prevent the buildup of sweat and sebum.
  • Avoiding occlusive clothing: Opt for loose-fitting, breathable clothing that allows air circulation and helps prevent moisture buildup.
  • Regularly washing towels and bedding: Laundering towels, pillowcases, and bedsheets regularly can help eliminate fungal spores and reduce the risk of reinfection.
  • Avoiding excessive use of oils and heavy moisturizers: Minimize the use of heavy oils and occlusive moisturizers that can promote the growth of Malassezia yeast.
  • Seeking professional advice: If over-the-counter treatments are ineffective or the condition worsens, consult a dermatologist for a proper diagnosis and personalized treatment plan.

How long does fungal acne last?

The duration of Malassezia folliculitis can vary depending on several factors, including the severity of the infection, the effectiveness of treatment, and individual factors. In mild cases, it may clear up within a few weeks with appropriate treatment. However, more severe or persistent cases may require longer treatment periods, ranging from several weeks to a few months.

Treatment typically involves antifungal medications, such as topical antifungal creams or oral antifungal medications. It’s important to follow the prescribed treatment regimen consistently and complete the full course of medication, even if symptoms improve or disappear before the treatment period ends.

Additionally, proper skin care practices can help manage and prevent future outbreaks. This includes using gentle, non-comedogenic cleansers, avoiding oil-based or heavy skincare products, keeping the skin clean and dry, and practicing good hygiene.


Fungal acne, caused by an overgrowth of Malassezia yeast, presents unique challenges in terms of diagnosis and treatment compared to bacterial acne. Recognizing the distinguishing features of fungal acne and seeking appropriate treatment is essential to effectively address this condition. By adhering to proper skincare practices, using antifungal treatments, and making necessary lifestyle modifications, individuals can manage Malassezia folliculitis and prevent its recurrence. Consulting a dermatologist is crucial for an accurate diagnosis and personalized treatment plan. With the right approach, individuals can successfully overcome the challenges posed by fungal acne and restore the health and appearance of their skin.
