Zinc oxide is very effective at reflecting UV rays, protecting the skin from sun damage. Therefore, it isn’t rare to see calamine in, or used as a sunscreen. The oxide also has antipruritic (meaning it soothes itches) and antiseptic properties. It mattifies, cleanses and soothes irritated and acne-prone skin.
The absorbent property of calamine keeps the skin soft and dry which makes the powder an ideal base for dusting powders and deodorants. It also benefits self-preserving products, as it absorbs and retains liquid ingredients in formulae and creates an inhospitable environment for the microorganisms responsible for decay.
