Staphylococcal Acne vs. Cystic Acne: Understanding the Difference and How to Treat Each
Acne is one of the most common skin conditions in the world, affecting millions of teenagers and adults alike. But not all acne is the same. While most people are familiar with hormonal or cystic acne, there’s another type that often goes undiagnosed — staphylococcal acne, caused by Staphylococcus bacteria. Though both conditions can appear similar on the surface, they differ significantly in their causes, symptoms, and treatment approaches. Understanding these differences can help you manage breakouts more effectively and prevent long-term skin damage.
What Is Staphylococcal Acne?
Staphylococcal acne, or staph-related folliculitis, occurs when Staphylococcus aureus bacteria infect the hair follicles. These bacteria naturally live on human skin, but under certain conditions — like broken skin, shaving cuts, or a weakened immune system — they can penetrate deeper layers and cause infection.
Unlike typical acne, staphylococcal acne is not caused by clogged pores or excess oil production. Instead, it’s a bacterial infection of the follicles that results in red, inflamed bumps or pus-filled pimples. In more severe cases, it can lead to abscesses or boils that are painful to touch.
Common Symptoms of Staphylococcal Acne
-
Clusters of red or white-headed bumps filled with pus
-
Painful or tender skin lesions
-
Rapidly spreading inflammation
-
Occasional fever or fatigue in serious infections
-
Lesions that may ooze or crust over
The most common areas affected include the face, scalp, chest, back, buttocks, and thighs — basically, anywhere hair follicles exist.
What Is Cystic Acne?
Cystic acne is a severe form of acne vulgaris that develops when oil (sebum), dead skin cells, and bacteria clog hair follicles deep under the skin. This triggers inflammation and leads to large, painful cysts that can last for weeks or even months.
Unlike staphylococcal acne, cystic acne is not primarily caused by infection from external bacteria but by internal factors such as hormonal changes, genetics, or excess sebum production. It’s most common among teenagers and young adults, but adults can also experience it, especially women during hormonal shifts.
Common Symptoms of Cystic Acne
-
Deep, painful lumps beneath the skin
-
Redness and swelling
-
Whiteheads or blackheads around the cyst area
-
Scarring or hyperpigmentation after healing
-
Commonly found on the face, shoulders, chest, and back
Cystic acne tends to recur in the same areas, making it frustrating and emotionally challenging for those who suffer from it.
How to Tell the Difference Between Staphylococcal Acne and Cystic Acne
While they can look similar, there are a few key differences that help distinguish staph-related breakouts from cystic acne:
| Feature | Staphylococcal Acne | Cystic Acne |
|---|---|---|
| Cause | Infection by Staphylococcus aureus bacteria | Hormonal imbalance, excess oil, and clogged pores |
| Appearance | Pus-filled bumps, sometimes with yellow crusts | Deep, painful cysts under the skin |
| Onset | Can develop suddenly and spread quickly | Develops gradually and lasts for weeks |
| Pain | Surface-level tenderness | Deep, throbbing pain |
| Treatment | Antibiotics and antiseptic care | Hormonal therapy, retinoids, or isotretinoin |
| Contagious? | Yes, in some cases | No |
If your acne appears suddenly, spreads quickly, or becomes painful to touch, it might be bacterial rather than hormonal. A dermatologist can perform a culture test to confirm if Staphylococcus aureus is present.
Treatment Options for Staphylococcal Acne
Because it’s a bacterial infection, staphylococcal acne typically requires antibiotic treatment. A dermatologist might prescribe:
-
Topical antibiotics: Such as mupirocin or clindamycin creams to target bacteria directly.
-
Oral antibiotics: Like doxycycline or cephalexin for moderate to severe infections.
-
Antiseptic washes: Using chlorhexidine or benzoyl peroxide washes can help reduce bacterial load.
-
Warm compresses: To ease pain and encourage drainage of pus.
-
Avoiding picking or squeezing: This can worsen infection and spread bacteria to nearby areas.
For recurrent staph infections, a doctor may recommend decolonization therapy, which involves using antibiotic ointments inside the nose and special antibacterial body washes.
Treatment Options for Cystic Acne
Cystic acne requires a different approach focused on reducing inflammation, controlling oil production, and balancing hormones. Common treatments include:
-
Topical retinoids: Such as adapalene or tretinoin to prevent clogged pores.
-
Oral medications: Including antibiotics for short-term use or hormonal treatments like birth control pills or spironolactone for women.
-
Isotretinoin (Accutane): A powerful medication used for severe, persistent acne.
-
Steroid injections: For rapidly shrinking large, painful cysts.
-
Gentle skincare: Using non-comedogenic cleansers and moisturizers to maintain skin balance.
Because cystic acne can lead to scarring, it’s best treated early by a dermatologist.
Prevention and Skin Care Tips
Whether you’re dealing with staphylococcal acne or cystic acne, prevention and hygiene are key to managing breakouts:
-
Wash your face twice daily with a mild, antibacterial cleanser.
-
Avoid sharing towels, razors, or makeup brushes.
-
Keep pillowcases and clothing clean.
-
Use non-comedogenic skincare and makeup products.
-
Avoid touching or picking at pimples.
-
Manage stress, which can trigger hormonal acne flare-ups.
When to See a Dermatologist
If your acne is painful, spreading, or not responding to over-the-counter treatments, consult a dermatologist. Persistent or severe breakouts might indicate an underlying bacterial infection or hormonal imbalance that requires professional treatment.
Final Thoughts
While staphylococcal acne and cystic acne can look similar, understanding their unique causes helps ensure proper treatment and faster recovery. Staph acne stems from bacterial infection and often needs antibiotics, while cystic acne is linked to hormones and inflammation deep beneath the skin. Both can be managed effectively with the right medical care and a consistent skincare routine. If you’re unsure which type you’re dealing with, it’s always best to get a dermatologist’s evaluation before starting any treatment.
