Inflammation triggered by yeast in oily skin

Seborrheic dermatitis is a chronic inflammatory condition driven by Malassezia, the same yeast behind fungal acne and dandruff. It typically shows up where your skin produces the most oil: scalp, around the nose, eyebrows, behind the ears, and the upper chest.

Dandruff is essentially scalp seb derm with less inflammation. They sit on the same spectrum, respond to the same treatment, and the line between them is fuzzy.

Managing it day to day

Chronic skin conditions respond to consistent, Malassezia-safe routines. Here's how to build yours.

1

Know what you're working with

Learn how Malassezia behaves and why these conditions flare. Our free Malassezia Handbook covers the science in plain language, and if you're unsure what you have, a dermatologist can confirm a diagnosis.

2

Audit what you're already using

Many mainstream products contain oils and fatty acids Malassezia feeds on, so a routine can quietly work against you. Run your labels through our free Ingredient Checker to spot ingredients that can make things worse.

3

Keep it under control

Fungal acne, seb derm, dandruff, and tinea versicolor can come back. A Malassezia-safe routine built on our collection of OTC solutions helps manage symptoms and keeps flares less frequent, so you're not starting over each time.
