Ingredient Notes
In a lab study, Malassezia was unable to grow on glycerin without the presence of fatty acids in the agar, indicating that it is not a fungal acne trigger.

Ingredient Notes
Niacinamide is a B vitamin, but not one of the B vitamins linked to Malassezia. Growth work names thiamine (B1) and pyridoxine (B6) as increasing growth alongside a lipid, without being required for it. Thiamine is not food for the yeast: it speeds the step that turns an amino acid into the carbon skeleton it uses, and supplying that skeleton directly removes the need for thiamine entirely. B3 is not named in any of that work. We rate niacinamide safe on that evidence rather than treating the whole B group as one risk, and nothing we hold shows it treats fungal acne either.
