Zinc Sulfate
A zinc mineral salt used in small amounts as an astringent and formulation aid.
What it does
Zinc Sulfate is a soluble zinc salt. In low amounts it has a mild astringent (tightening) effect on the skin surface and supplies zinc ions used in some formulas. It is a formulation ingredient rather than a skin active.
