Physical Sunscreen
Physical sunscreen is a type of sun protection product that uses natural minerals (like zinc oxide or titanium dioxide) to create a protective barrier on the skin. Unlike chemical sunscreens that absorb UV rays, physical sunscreens work by reflecting or "bouncing" harmful sun rays away from the skin. In cosmetics industry job descriptions, this term often appears when companies are looking for professionals who understand sun protection formulation, product development, or quality control. It's also sometimes called "mineral sunscreen" or "inorganic sunscreen" in technical documents.
