Ingredient N° 29
A mineral UV filter with broad-spectrum coverage.
Zinc oxide is a mineral sunscreen filter that helps protect across UVA and UVB wavelengths. Modern formulas reduce the classic white cast, but finish and protection depend on the complete tested sunscreen, not the ingredient in isolation.
Worth knowing
Use the labeled amount and reapply; an ingredient list alone cannot confirm a sunscreen’s real protection.
