Not All Acne Is the Same: How to Treat Hormonal vs. Fungal vs. Bacterial Acne

Different types of acne need different treatments. Dermatologists use specific ingredients — like benzoyl peroxide, salicylic acid, or antifungals — depending on what type it is.

Introduction: Why One-Size-Fits-All Acne Treatment Doesn’t Work

Acne isn’t just about clogged pores and teenage hormones — it’s a complex skin condition with multiple root causes. Many people spend years trying product after product without results, not because the ingredients are bad, but because they’re targeting the wrong type of acne. What clears up one breakout might make another worse.

In this blog, we’ll break down the three major types of acne — hormonal, bacterial, and fungal — how to recognize them, what causes each one, and the most effective, science-backed ways to treat them. Whether you’re struggling with chin breakouts, itchy forehead bumps, or painful cysts, understanding your acne type is the first step toward getting real results.

1. What Is Acne, Really? A Quick Scientific Primer

Acne occurs when pores (hair follicles) become clogged with oil (sebum), dead skin cells, and sometimes bacteria or yeast, leading to inflammation. But depending on what’s clogging the pore — and how your skin reacts — you’ll get very different kinds of acne.

Types of Acne Lesions

  • Comedones: whiteheads and blackheads (non-inflammatory)
  • Papules: red bumps
  • Pustules: pimples with pus
  • Nodules and cysts: deeper, painful lumps
  • Fungal acne: itchy, uniform pimples from yeast, not bacteria

2. Hormonal Acne: The Inside-Out Breakout

What It Looks Like

  • Deep, tender cysts
  • Usually found on the jawline, chin, and lower cheeks
  • Worsens before or during menstruation
  • Often resistant to typical acne treatments like salicylic acid or benzoyl peroxide

The Root Cause

Hormonal acne is driven by fluctuations in androgens (like testosterone), which increase sebum production and lead to clogged pores and inflammation.

Who Gets It?

  • Teenagers going through puberty
  • Adults with PCOS or other hormonal imbalances
  • Women during menstrual cycles, pregnancy, or menopause

Best Treatments

Topical Options

  • Retinoids (adapalene, tretinoin): help prevent pore blockages and reduce inflammation
  • Azelaic acid: reduces inflammation and gently exfoliates without irritation
  • Niacinamide: helps control sebum and calm redness

Oral Medications (prescribed by a dermatologist)

  • Spironolactone: blocks androgen receptors; often used in adult women
  • Combined oral contraceptives: regulate hormones to reduce sebum
  • Isotretinoin (Accutane): used for severe, resistant cases

Lifestyle Support

  • Reduce high-glycemic foods and dairy (linked to sebum production)
  • Manage stress — cortisol also affects androgens
  • Maintain consistent sleep and blood sugar levels

3. Bacterial Acne: The Classic Breakout

What It Looks Like

  • Red, inflamed papules and pustules
  • White or yellow pus-filled pimples
  • Usually found on the T-zone, back, or shoulders
  • May feel painful or warm to the touch

The Root Cause

Bacterial acne is primarily caused by Cutibacterium acnes (formerly Propionibacterium acnes) — a naturally occurring skin bacteria that feeds on sebum and triggers inflammation when trapped in clogged pores.

Who Gets It?

  • Teens and young adults
  • Athletes or those who sweat heavily
  • People with oily skin types

Best Treatments

Topical Options

  • Benzoyl Peroxide (2.5–5%): kills C. acnes bacteria on the skin’s surface
  • Salicylic Acid (BHA): unclogs pores and reduces oil buildup
  • Retinoids: regulate cell turnover to prevent clogged follicles

Oral Antibiotics (short-term use)

  • Doxycycline, minocycline, or clindamycin (topical or oral)

Routine Tweaks

  • Wash face after sweating
  • Avoid heavy, pore-clogging makeup or sunscreen (look for non-comedogenic labels)
  • Don’t pick or pop pimples — it spreads bacteria

4. Fungal Acne: Not Actually Acne at All

What It Looks Like

  • Tiny, uniform red or flesh-colored bumps
  • Often appear on the forehead, chest, shoulders, or back
  • Itchy, unlike bacterial or hormonal acne
  • Doesn’t respond to normal acne treatments — might get worse with them!

The Root Cause

Fungal acne, or Malassezia folliculitis, is caused by yeast overgrowth in the hair follicles. This yeast (Malassezia) lives on everyone’s skin, but can overgrow in hot, humid conditions or after antibiotic use.

Who Gets It?

  • Athletes or people in hot, humid climates
  • People who wear tight clothing or sweat a lot
  • Those using antibiotics or immune-suppressing medications

Best Treatments

Topical Antifungals

  • Ketoconazole cream/shampoo (1–2%) — use as a face or body mask
  • Zinc pyrithione soap (like Vanicream Z-Bar or Noble Formula)
  • Selenium sulfide shampoo — doubles as a mask

Oral Antifungals (for resistant cases)

  • Fluconazole or itraconazole (prescribed)

Prevention Tips

  • Use breathable, sweat-wicking clothes
  • Shower immediately after sweating
  • Avoid using rich creams or oils with esters or fatty acids that feed Malassezia (e.g., olive oil, lauric acid)

5. How to Tell What Kind of Acne You Have

Ask Yourself:

SymptomMost Likely Cause
Deep, painful lumps on chin?Hormonal
Whiteheads and inflamed pimples on cheeks/forehead?Bacterial
Tiny, itchy bumps on forehead/back?Fungal
Acne worsens around period?Hormonal
Acne appears after antibiotics?Fungal
Pimples improve with benzoyl peroxide?Bacterial
Pimples don’t respond to anything?Could be a mix — or misdiagnosed

Pro Tip:

If you’re not sure, try taking a 3–5 day break from actives, use a gentle routine, and slowly reintroduce one ingredient at a time. Or consult a dermatologist and request a skin swab or culture.

6. Can You Have More Than One Type? (Spoiler: Yes)

Most people have mixed acne, especially adults:

  • Hormonal acne on the jawline
  • Bacterial acne on the cheeks
  • Fungal acne on the forehead or chest

In these cases, a multifaceted treatment plan is required. For example:

  • Use benzoyl peroxide on cheeks
  • Ketoconazole on forehead
  • Retinoids at night to regulate cell turnover

7. Common Mistakes in Acne Treatment

Using the wrong ingredients

  • Treating fungal acne with benzoyl peroxide can make it worse
  • Hormonal acne doesn’t respond well to drying agents

Over-cleansing or over-exfoliating

  • Strips the barrier, leading to more inflammation and breakouts

Using too many products at once

  • Overloading your skin can cause irritation or mask what’s really working

Expecting instant results

  • Acne treatment takes 6–12 weeks of consistent use to show true improvement

8. Creating a Custom Acne-Fighting Routine (By Type)

Hormonal Acne Routine

  • AM: Gentle cleanser → Niacinamide serum → Oil-free moisturizer → SPF
  • PM: Cleanser → Azelaic acid or adapalene → Barrier-supporting moisturizer

Bacterial Acne Routine

  • AM: Salicylic acid cleanser → Niacinamide → Moisturizer → SPF
  • PM: Benzoyl peroxide or retinoid → Moisturizer

Fungal Acne Routine

  • AM: Zinc pyrithione cleanser → Light, oil-free moisturizer → SPF
  • PM: Ketoconazole shampoo (5–10 min mask) → Gel moisturizer

Summary: Key Takeaways

  • Hormonal acne is deep, cystic, and needs internal and hormonal support.
  • Bacterial acne is inflamed, surface-level, and responds to salicylic acid and benzoyl peroxide.
  • Fungal acne is itchy, uniform, and needs antifungal care — not typical acne treatments.
  • Knowing your acne type helps avoid wasted time, money, and unnecessary irritation.
  • You can have more than one type — so observation and tailored routines are key.
  • When in doubt, consult a dermatologist and simplify your routine.

Understanding your acne type is the single most important step in treating it effectively. Stop playing guessing games and start building a plan that works with your skin — not against it.
