ZINC SULFATE

Zinc sulfate is a common cosmetic ingredient that acts as an astringent, helping to tighten pores and control oil production, and an antimicrobial agent, preventing the growth of bacteria and fungi. It also functions as a preservative, increasing product shelf life, and can offer anti-inflammatory and skin-brightening benefits. Zinc sulfate is used in a wide range of products, including skincare, hair care, and oral care, often at low concentrations, and its use is regulated by safety committees to ensure purity and appropriate usage levels.
