Risks & Warnings
Main concerns are formulation-related rather than comedogenic: eye-area stinging, staining, or irritation in sensitive users can occur. As with any color additive, it must be used only within regulatory allowances and supplier specifications. Rare sensitivity is possible, but it is generally considered low risk in rinse-off and leave-on cosmetics.
