Malassezia

Malassezia yeasts are members of the microbiota of healthy human skin. They play a significant role in several skin conditions, such as dandruff, pityriasis versicolor, and seborrheic dermatitis.

Malassezia yeasts are also the cause of Malassezia folliculitis, commonly known as fungal acne. This condition arises when the yeasts grow within human hair follicles, resulting in acne-like breakouts typically seen on the T-zone, shoulders, chest, and back. These breakouts usually manifest as clusters of small whiteheads, often accompanied by itchiness and inflammation.

Common acne and Malassezia folliculitis are often mistaken due to their similar appearances. As bacterial acne treatments do not address the root cause as a fungal problem, a misdiagnosis can lead to persistent symptoms lasting for years.

Root Causes

Malassezia yeasts are lipid-dependent organisms and feed on fatty acids with carbon chain lengths of 11-24. The yeasts can also thrive on compounds derived from these acids, including esters and fatty substances like butters, waxes, or oils.

Several factors contribute to the overgrowth of Malassezia, including antibiotic use, oral steroids, and immunosuppression, high sebum production, and excessive sweating. The lipids present in sweat and sebum provide an abundant food source for the yeast and encourage their growth. Topical products containing lipids can also nourish Malassezia and trigger adverse reactions.

Treatment approaches for Malassezia-related skin conditions typically involve balancing the environment to keep the yeasts in check.
