Fungal Acne (Malassezia Folliculitis)
Fungal Acne (Malassezia Folliculitis) — an acne-like condition caused by an overgrowth of Malassezia yeast within the hair follicles rather than by bacteria. It produces clusters of small, uniform, often itchy bumps, and unlike true acne it does not respond to standard antibacterial acne treatments.
Key points
- It is not technically acne but a form of folliculitis triggered by yeast that naturally lives on the skin overgrowing in warm, oily, or humid conditions.
- Bumps tend to be small, uniform in size, and clustered on the forehead, chest, back, and shoulders, and they are frequently itchy.
- Sweat, occlusion, humidity, and prolonged antibiotic use can encourage the yeast overgrowth that drives flare-ups.
- It typically improves with antifungal treatments rather than benzoyl peroxide or antibiotics, which target bacterial acne.
Frequently asked
How can I tell fungal acne apart from regular acne?
Fungal acne usually appears as small, uniform, itchy bumps that cluster together, while typical acne varies in size and includes blackheads and whiteheads. If breakouts are itchy and fail to respond to standard acne products, a dermatologist can confirm the difference.
Can skincare products make fungal acne worse?
Yes, certain oils, fatty acids, and esters can feed Malassezia yeast and aggravate the condition. Choosing lightweight, non-occlusive products and showering promptly after sweating can help reduce flare-ups.
