Zinc Sulfate
What this ingredient generally does
Zinc Sulfate is a zinc salt that acts as an astringent, tightening and toning the skin's surface. It also serves antimicrobial and oral-care roles, keeping the formula in check and used in mouth products where it fights plaque. On labels it may simply appear as a zinc salt.
