Cystic Acne: Causes and Treatments

Dermatologist-Approved Guide to Understanding and Managing Severe Acne

Cystic acne is one of the most severe and emotionally distressing forms of acne vulgaris. Unlike typical blackheads or whiteheads, cystic acne lesions form deep beneath the skin, often resulting in painful, inflamed bumps that can persist for weeks and leave scars. While it can affect anyone, it’s particularly common in teenagers and adults with hormonal imbalances or a genetic predisposition.

This article explores what causes cystic acne, why it behaves differently from other acne types, and the most effective dermatologist-recommended treatments — both medical and at-home — to help you manage it safely.

Dr. Whitney Bowe, MD, board-certified dermatologist, explains:
“Cystic acne is not caused by poor hygiene or diet alone — it’s a deep inflammatory condition often influenced by hormones and genetics. It needs targeted medical care, not harsh over-the-counter treatments.”

Understanding Cystic Acne

What Is Cystic Acne?

Cystic acne is a severe, inflammatory form of acne characterized by large, red, tender nodules or cysts beneath the skin’s surface. These cysts occur when oil, dead skin cells, and Cutibacterium acnes (formerly Propionibacterium acnes) bacteria clog pores, leading to deep infection and inflammation.

Unlike superficial pimples, cystic lesions are painful, persistent, and prone to scarring. They often appear on the face, jawline, chest, shoulders, and back — areas with a high density of sebaceous (oil) glands.

Who Gets Cystic Acne?

While anyone can develop cystic acne, certain groups are more susceptible:

• Teenagers undergoing puberty

• Women experiencing hormonal fluctuations (menstrual cycle, pregnancy, PCOS)

• Adults under chronic stress

• Individuals with a family history of severe acne

Dr. Rachel Nazarian, MD, notes:
“Cystic acne tends to run in families. Genetics play a major role in how your skin reacts to inflammation and oil production.”

Causes of Cystic Acne

Cystic acne develops due to a complex interplay of biological, hormonal, and environmental factors.

1. Hormonal Imbalances

Androgens — male hormones present in both men and women — increase sebum (oil) production. During puberty, menstrual cycles, or conditions like PCOS (polycystic ovary syndrome), these hormone surges trigger excessive oiliness and clogged pores.

Women often experience cyclical cystic breakouts around the jawline and chin before menstruation.

2. Overactive Sebaceous Glands

An overproduction of oil can clog pores and trap bacteria, creating the perfect environment for cyst formation.

3. Bacterial Overgrowth

Cutibacterium acnes thrives in clogged follicles, releasing inflammatory substances that cause redness, swelling, and pain.

4. Inflammation

Chronic inflammation deep in the dermis leads to painful cyst formation and post-inflammatory hyperpigmentation (PIH) or scarring.

5. Genetic Predisposition

If one or both parents had cystic acne, you’re more likely to experience it due to inherited traits affecting sebum production and immune response.

6. Lifestyle and External Factors

• Stress: Elevates cortisol, which worsens inflammation and oil secretion.

• Diet: High-glycemic foods and dairy may contribute to flare-ups.

• Cosmetics: Heavy or comedogenic makeup can worsen blockage.

• Humidity and Sweat: Frequent occlusion or friction (helmets, masks) can aggravate breakouts.

Dr. Joshua Zeichner, MD, adds:
“Acne is not caused by dirty skin. Overwashing or harsh scrubbing actually damages the skin barrier and worsens cystic lesions.”

Symptoms of Cystic Acne

Cystic acne presents with:

• Large, red, painful nodules under the skin

• Tenderness and swelling

• Deep cysts filled with pus or sebum

• Scarring or pigmentation after healing

• Emotional distress due to visible lesions

Painful cystic acne can significantly impact self-esteem, social confidence, and mental health. Early dermatologist intervention can prevent complications and permanent scars.

Diagnosis: How Dermatologists Identify Cystic Acne

A dermatologist can diagnose cystic acne through clinical examination, evaluating:

• Lesion depth and inflammation

• Acne pattern (hormonal vs. bacterial)

• Personal and family history

• Hormonal profile (especially in women with irregular cycles or PCOS)

In some cases, blood tests may assess androgen levels or underlying hormonal imbalances.

Treatments for Cystic Acne

Cystic acne rarely responds to over-the-counter products. It requires prescription medications, and in some cases, procedural interventions.

1. Topical Prescription Treatments

a. Retinoids (Tretinoin, Adapalene, Tazarotene)

• Help unclog pores, reduce inflammation, and enhance skin cell turnover.

• Often used as maintenance therapy after oral medication.

• Initial irritation (“retinoid purge”) is common but temporary.

b. Benzoyl Peroxide

• Antibacterial agent that reduces C. acnes and inflammation.

• Effective when combined with topical or oral antibiotics.

c. Topical Antibiotics (Clindamycin, Erythromycin)

• Reduce bacterial colonization and inflammation.

• Usually prescribed short-term alongside benzoyl peroxide to prevent resistance.

d. Azelaic Acid

• Reduces redness, pigmentation, and bacterial activity.

• Excellent for post-acne dark spots and sensitive skin.

2. Oral Medications

a. Oral Antibiotics

• Commonly used: Doxycycline, Minocycline, Erythromycin.

• Reduce bacterial overgrowth and inflammation.

• Typically prescribed for 3–6 months with concurrent topical treatment.

• Not suitable for long-term use due to resistance risk.

b. Hormonal Therapy (for Women)

• Combined Oral Contraceptives (COCs): Regulate hormones that trigger excess oil production.

• Spironolactone: Blocks androgen receptors, reducing sebum production.

• Effective for jawline or lower-face cystic acne linked to hormonal changes.

Dr. Heather Woolery-Lloyd, MD, says:
“Hormonal therapy can dramatically improve cystic acne in women, especially those whose breakouts flare around their menstrual cycles.”

c. Isotretinoin (Oral Retinoid)

• Gold-standard treatment for severe cystic acne.

• Shrinks sebaceous glands, reduces oil production, prevents blocked pores, and decreases inflammation.

• Course typically lasts 4–6 months.

• Requires regular monitoring of liver function and lipid levels due to potential side effects.

• Strict pregnancy prevention (iPledge program in the U.S.) is mandatory for women.

Dr. Nazarian emphasizes:
“Isotretinoin can be life-changing for cystic acne patients. It provides long-term remission in most cases when properly monitored.”

3. In-Clinic Dermatological Procedures

a. Corticosteroid Injections

• Instantly reduce inflammation and pain in large cysts.

• Useful for emergency cases before events or severe flare-ups.

b. Chemical Peels

• Use salicylic or glycolic acid to exfoliate, unclog pores, and reduce scarring.

• Not suitable during active cystic breakouts but excellent for maintenance.

c. Drainage and Extraction

• Performed only by dermatologists to safely remove pus and prevent scarring.

• Never attempt to pop cysts at home.

d. Laser and Light Therapies

• Blue light and pulsed-dye laser treatments target acne-causing bacteria and inflammation.

• Can reduce recurrence and improve skin texture.

Home Care and Lifestyle Support

Cystic acne management extends beyond prescriptions. Supportive care enhances treatment outcomes and reduces flare-ups.

Gentle Skincare Routine

• Cleanser: Use mild, non-comedogenic formulas with salicylic acid.

• Moisturizer: Hydrating, oil-free, and fragrance-free.

• Sunscreen: Broad-spectrum SPF 30 or higher, non-comedogenic.

Avoid Triggers

• Limit dairy and high-glycemic foods (white bread, sugary drinks).

• Manage stress with meditation, yoga, or adequate sleep.

• Avoid occlusive makeup; always remove cosmetics before bed.

Psychological Support

Cystic acne can affect self-esteem. Dermatologists often recommend support groups or counseling for those struggling emotionally.

Dr. Bowe reminds:
“Skin and mental health are closely connected. Treating cystic acne requires addressing both the physical and emotional aspects.”

Prevention and Maintenance

Even after clearing cystic acne, maintenance therapy prevents relapse.

• Continue topical retinoids to keep pores clear.

• Use non-comedogenic skincare products consistently.

• Schedule periodic dermatologist visits to monitor for recurrence.

Patients with persistent hormonal acne may remain on low-dose spironolactone or COCs as maintenance therapy.

Possible Complications

If untreated or improperly managed, cystic acne can lead to:

• Permanent scarring (ice-pick, boxcar, rolling scars)

• Post-inflammatory hyperpigmentation

• Emotional distress and social anxiety

Early medical intervention is the best strategy to prevent scarring and long-term consequences.
