Sun filters come in two families. Organic filters absorb UV and turn it into a little heat; mineral filters such as zinc oxide sit on the skin and absorb and scatter it. Zinc oxide covers a broad range on its own, UVB and much of UVA, which is why it has been in sun care for a century.
Its one vanity is whiteness. A mineral filter can leave a pale film, the ghost of beach holidays past. We tint both sticks and the Tinted Sunscreen with iron oxides, so they blend to a natural finish instead.
A stick only protects as well as you apply it. Several swipes per area, then blend; reapply every two hours and after swimming or towelling.
