Fungal acne, also known as Malassezia folliculitis, is caused by an overgrowth of yeast on the skin, unlike regular acne, which is typically caused by bacteria and clogged pores. It often appears as small, itchy, uniform bumps, usually on the chest, back, or forehead. Skincare ingredients safe for fungal acne include salicylic acid, benzoyl peroxide, azelaic acid, niacinamide, and lightweight non-oily moisturizers, while ingredients like oils high in oleic acid, esters, and fatty alcohols can feed the yeast and trigger flare-ups. A simple fungal-acne-safe routine involves: gentle cleansing with a low-lather or antifungal cleanser, moisturizing with a lightweight, non-comedogenic lotion, and spot treatment using safe actives like salicylic or azelaic acid, while avoiding heavy oils, occlusive creams, and ingredients that promote yeast growth.
