Science
Mechanism of Action
It imparts opacity and brightness as a pigment and provides bulking. In nanoparticle form, it has shown potential in wound healing by regulating redox homeostasis and promoting fibroblast viability.

Dusting Analysis
No specific data suggests it's commonly dusted; its primary roles as a pigment and bulking agent typically require higher, functional percentages.
The Formula
Formulation
Stability
Zinc sulfide is nearly insoluble in water and stable when dry, but it decomposes in strong acidic conditions and oxidizes slowly in air when moist.
Conflicts
- strong acids
- strong oxidizing agents
- moisture
Safety
Safety Profile
While FDA approved for limited, infrequent use in facial makeup (up to 10%), it's not for daily or eye area use. Contact with acids releases toxic hydrogen sulfide gas, and environmental accumulation is a concern.

Verdict
Due to its limited FDA approval for infrequent use, environmental concerns, and potential for toxic gas release, Zinc Sulfide is generally not recommended for routine skincare.
