Description
Zinc Oxide is a highly versatile, mineral-based skincare ingredient known for its soothing, protective, and UV-reflecting properties. It is widely used in sunscreens, baby care, medicated creams, and formulations designed for sensitive or irritated skin. This naturally occurring inorganic compound forms a protective barrier on the skin, helps calm inflammation, and offers broad-spectrum UVA/UVB protection. Its non-comedogenic, non-irritating profile makes it suitable for all skin types, including acne-prone, reactive, and delicate skin.
