Could You Have Fungal Acne? We Asked Dermatologists How to Tell

"If patients have excessively oily skin, or are prone to excessive sweating, fungal acne can occur," explains Dr. Mamelak. "It can also pop up in patients wearing a tight hat (or helmet) or use thick emollients or creams. Similarly, if patients have been on systemic steroids, or have suppressed immune systems, fungal acne can also develop."

Your hair care products can be another surprising cause behind fungal acne: Dr. Shainhouse explains that oil-based scalp and hair care products can sometimes lead to clogged pores, which in turn leads to fungal acne. She adds that dandruff is usually triggered by the same type of yeast that triggers fungal acne — so watch out for dandruff!
