Zinc Sulfate
Zinc sulfate is an inorganic zinc salt supplied as a water-soluble crystalline powder for cosmetic use. Toners and spot products add it for astringent and sebum-moderating aims, though real-world cosmetic benefits are typically modest.

Our take
Is Zinc Sulfate a Good Ingredient?
It rates Fair because of limited clinical support for acne or oil control and a higher likelihood of stinging or dryness, especially in leave-on use or at high concentrations.
What it does
Skin Benefits
May temper oiliness and support breakout-focused routines, though outcomes are generally modest and evidence is limited. Best suited for short-contact use to reduce dryness.
Where you'll find it
Uses in Skincare & Cosmetics
Seen in toners, spot treatments, and clarifying mists; occasionally added to micellar waters for oily or blemish-prone skin.
Before you use it
Safety
Can cause burning, dryness, or redness, particularly on sensitive or compromised skin. Prefer short-contact use and avoid the eye area.
