|---|---|---|
Contact irritation (redness, stinging) | Uncommon | Possible in sensitive skin, often related to fermentation byproducts. |
Allergic contact dermatitis | Rare | Sensitization to ferment metabolites or residual proteins. |
Pigment-related staining or transient discoloration | Rare | Monascus pigments may temporarily tint skin in high concentrations. |
Citrinin-related concerns | Very rare | Some Monascus strains can produce the mycotoxin citrinin; cosmetic-grade material is typically purified/controlled. |
