The skin becomes clean, free from dust and dirt, and helps to prevent infections. As an antimicrobial agent, it inhibits microbial growth and protects the skin from conditions like acne Zinc sulfate also brightens up the skin and makes it even-toned. It acts as a preservative, increasing the product's shelf life by preventing contamination by fungi and bacteria.
