Why it works for Fungal acne (Malassezia folliculitis)

Kills the yeast (Malassezia) behind fungal acne. It floods the yeast cells with copper to toxic levels and shuts down the parts they need to breathe. It is an FDA-approved over-the-counter dandruff ingredient, and people use it off-label as a 1-2% face or body wash (lather, leave on 3-5 minutes, then rinse). For the related condition dandruff (seborrheic dermatitis), trials show it works about as well as 2% ketoconazole.
