Fungal acne checker

Fungal acne looks like many tiny bumps of the same size, 1 to 2 millimetres across, that are red or skin-colored and may have pus on top. A 2025 review in the Journal of Fungi says the bumps sit around hair follicles on the upper body, chest, back, shoulders and face. The review names the absence of blackheads, whiteheads, deep lumps and cysts as the main feature that separates fungal acne from regular acne.

Fungal acne is a real skin condition, and doctors call it Malassezia folliculitis or Pityrosporum folliculitis. It happens when a yeast called Malassezia, which lives on the skin of almost all healthy people, grows too much inside hair follicles. Doctors first described it in 1969, according to a 2025 review in the Journal of Fungi. Medical papers class it as a folliculitis, which means inflamed hair follicles.

Fungal acne is often itchy, and some people with it feel no itch. In a 2018 study of 110 young patients in the Journal of the American Academy of Dermatology, 65 percent of those whose records noted it reported itch. A 2025 review describes another study of 48 patients, where 37 had itch and 11 had no symptoms at all. A lack of itch does not rule fungal acne out, and a doctor confirms it.

Fungal acne usually has no whiteheads or blackheads. Doctors call these plugged pores comedones, and a 2025 review in the Journal of Fungi describes fungal acne as "devoid of comedones". Fungal acne can still have small bumps with white or yellow pus on top, which doctors call pustules. The American Academy of Dermatology describes a whitehead as a pore plugged with oil and dead skin cells that looks raised and white or skin-colored.

Heat, sweat, humid weather, covered skin, antibiotics and a weakened immune system are the triggers that medical reviews link to fungal acne. A 2025 review in the Journal of Fungi says humidity, skin that stays covered, antibiotics and a weakened immune system help the yeast overgrow. In one study it cites, 71 percent of patients said sweating made the bumps worse. A 2018 study found that more than 75 percent of 110 patients had recently taken antibiotics for acne.

Teenagers and young adults get fungal acne most often, and it is more common in males, according to a 2025 review in the Journal of Fungi. The review links this to the higher oil production of the skin at that age. It also reports fungal acne more often in people who live in hot climates, and in people with a weakened immune system, such as people with HIV, people who have had an organ transplant and people taking steroid medicines.

A doctor can tell you if bumps are fungal acne by examining them, and may test a sample to confirm it. The easiest test to get is to scrape a few skin cells or some material from a bump, add a liquid called potassium hydroxide, and look for yeast under a microscope, according to a 2025 review in the Journal of Fungi. Doctors may also use a special light, a skin magnifier or, when needed, a small skin sample called a biopsy.

Fungal acne on the face is the same yeast condition that appears on the chest and back, and the face is a common place for it. In a study of 49 patients cited by a 2025 review in the Journal of Fungi, 57 percent had bumps on the face. A 2018 study found the bumps typically on the forehead, running into the hairline. The review notes that fungal acne only on the face is harder to tell apart from regular acne.

Deep lumps and cysts are not a typical sign of fungal acne. A 2025 review in the Journal of Fungi names the absence of comedones, nodules and cysts as a main feature that separates fungal acne from regular acne. A 2014 study in the Annals of Dermatology says severe cases can include nodules and cysts. Deep or painful lumps are a reason to see a doctor, whatever their cause, because only an exam can say what they are.

Antibiotic pills such as doxycycline are almost always ineffective for fungal acne and may make it worse, according to a 2025 review in the Journal of Fungi. The review explains that antibiotics upset the normal balance of germs on the skin, which lets the yeast overgrow. If you take an antibiotic and your bumps are not improving, ask the doctor who prescribed it whether fungal acne could be the cause before you change anything.

Fungal acne often comes back. A 2025 review in the Journal of Fungi says it responds quickly to antifungal treatment and returns often, and that long-term treatment may be needed to keep it away. The review also says patients should learn how sweat, skin that stays covered and unneeded antibiotics can bring the bumps back. If the bumps return, a doctor can explain which plan fits you.

A doctor treats fungal acne, for example a dermatologist, which is a doctor who specializes in skin. The American Academy of Dermatology says a board-certified dermatologist can tell whether acne-like breakouts are folliculitis, because infected hair follicles can look like acne. Fungal acne is a folliculitis caused by yeast. Once a doctor confirms it, a 2025 review in the Journal of Fungi says treatment uses antifungal medicine on the skin or by mouth.

The Skinli fungal acne checker cannot diagnose fungal acne or any other condition. It compares your answers with eight signs that medical reviews describe, and tells you whether your answers match many, some or few of them. No study has tested this checklist. A doctor confirms fungal acne, for example by looking at scraped skin cells under a microscope. Use your result to describe your bumps to a doctor.
