Azelaic Acid and fungal acne
No known trigger
Why it's not a known trigger
A nine-carbon dicarboxylic acid; below the C11-C24 uptake range, and its two acid ends make it far more water-soluble than the long fats Malassezia yeast harvests.
Real-world nuance: dermatologists do prescribe it for fungal-acne-prone skin, and it can genuinely help the condition — via anti-inflammatory, antibacterial and keratolytic action on the inflammation and clogged follicles around the yeast. But that is not the same as acting on the yeast: Malassezia itself makes and secretes this acid, and lab tests found little response of Pityrosporum ovale even at high concentration. Hence neutral, not helpful.
