Zinc PCA and fungal acne
No known trigger
Why it's not a known trigger
The zinc salt of a small cyclic humectant from the skin’s own moisturizing chemistry; water-soluble, no fatty chain.
Zinc may mildly help oily skin and ordinary acne bacteria, but the direct Malassezia record is too thin to call it helpful — not in the same league as zinc pyrithione.
