Fungal Acne vs. Bacterial Acne: How to Spot the Difference

If you’ve been battling stubborn skin breakouts, you may have heard the term "fungal acne" thrown around, but what exactly is fungal acne? And how does it differ from the more common bacterial acne?

While they share some symptoms, fungal acne and bacterial acne have very different causes and require unique treatment approaches. Getting the diagnosis right means faster relief and clearer skin.

At Dr Su, we understand the nuances of various skin concerns. This guide will help you identify fungal versus bacterial acne, understand their differences, and explore the best treatment options, including how our dermatologist-formulated skincare can help you on your journey to healthy skin.

What Is Bacterial Acne?

Bacterial acne, medically known as “acne vulgaris,” is the classic acne type most people recognize. It develops when hair follicles become clogged with excess oil (sebum), dead skin cells, and bacteria known as Cutibacterium acnes (formerly Propionibacterium acnes).

Key Characteristics of Bacterial Acne:

• Varied appearance: You’ll see blackheads, whiteheads, inflamed red pimples, pustules (pus-filled bumps), nodules, and cysts.
  
• Location: Commonly affects the face (cheeks, forehead, chin), neck, chest, shoulders, and upper back.
  
• Pain level: Pimples can be tender or painful.
  
• Progression: If untreated, it may lead to scarring.
  

Bacterial acne often shows up during puberty, but it can persist or develop anew in adulthood, especially due to hormonal changes, stress, poor skincare habits, or diet. knyamed+1

What Is Fungal Acne?

Fungal acne is less well-known and frequently misdiagnosed. Unlike bacterial acne, fungal acne isn’t caused by bacteria but rather by a yeast (fungus) called Malassezia that naturally lives on the skin. When this yeast multiplies excessively inside hair follicles, it causes tiny, uniform, itchy bumps known as Malassezia folliculitis.

Key Characteristics of Fungal Acne:

• Uniform bumps: Clusters of small, red or white bumps that are usually all the same size.
  
• Location: Prefers oily, sweaty areas like the forehead (especially hairline), upper back, chest, and shoulders.
  
• Itching: Fungal acne tends to be very itchy, unlike bacterial acne.
  
• Lack of blackheads/whiteheads: Usually, no traditional clogged pores or pus.
  
• Stubborn: Often worsens with antibacterial acne treatments and requires antifungal care. healthline+1

How to Tell the Difference Between Fungal and Bacterial Acne?

Identifying whether your breakouts are bacterial or fungal forms the basis of effective treatment. Here’s how to spot key differences:

Why Does Getting the Right Diagnosis Matter?

Treating fungal acne with bacterial acne products (like benzoyl peroxide or antibiotics) can make fungal acne much worse. Similarly, using antifungal agents  won’t clear bacterial acne. Misdiagnosis leads to frustration, prolonged breakouts, and sometimes scars.

The right treatment approach depends heavily on understanding which form you have.

Treatment Options for Bacterial Acne

If your acne is bacterial, it generally responds well to:

• Benzoyl peroxide: Kills acne-causing bacteria and reduces inflammation
  
• Salicylic acid: Penetrates pores to unclog them and soothe skin
  
• Retinoids (prescription based): Speed up cell turnover, prevent clogged follicles
  
• Non-comedogenic moisturisers: Hydrate without clogging pores
  
• Consistent gentle cleansing: Twice daily with sulfate-free formulas
  

Dr Su’s skincare range includes targeted products with these active ingredients, formulated for Indian skin to balance oil without irritation.

Treatment Options for Fungal Acne

Fungal acne requires a different approach:

• Antifungal cleansers: Contain ketoconazole or selenium sulfide to reduce yeast levels
  
• Avoid heavy oils, thick creams, and comedogenic products: These worsen yeast growth
  
• Wear breathable fabrics: Helps reduce sweating and moisture buildup
  
• Proper hygiene: Shower after exercise; clean pillowcases and towels frequently
  
• Oral antifungals: Prescribed in severe cases by dermatologists
  
  

Lifestyle Tips to Manage Both Types

• Avoid excess touching or picking of pimples
  
• Use non-comedogenic, lightweight makeup and sunscreens
  
• Maintain a balanced diet rich in antioxidants, omega-3s, and probiotics
  
• Manage stress through mindfulness and adequate sleep
  
• Maintain scalp hygiene; fungal acne often coexists with scalp issues
  
  

When to Ask for Expert Advice

If breakouts are persistent, worsening, or unusually painful regardless of presumed cause, consult healthcare providers for proper diagnosis. They may perform skin swabs or tests to confirm fungal or bacterial involvement and recommend personalized treatments.
