About this sunscreen
Mossa Natural Sun SPF 20 is a pure mineral sunscreen using Zinc Oxide as its only filter, suiting those who prefer all-mineral formulas. It dries to a matte finish and is generally non-stinging with a low pore-clogging profile, but it carries a high white cast and a somewhat heavier feel, and it performs poorly as a makeup base. With SPF 20 it offers moderate protection and a score of 67.0, making it a reasonable mineral pick where white cast is not a concern.

Does Mossa Natural Sun SPF 20 leave a white cast?
Yes, white cast is rated high. As a pure Zinc Oxide mineral sunscreen, it can leave a visible white film and feels somewhat heavier on the skin.
Does the Mossa Natural Sun Spf 20 work under makeup?
It performs poorly as a makeup base, so it is better worn on its own. It dries to a matte finish, which suits oily skin, but the white cast can show through makeup.
Is it mineral or chemical?
It is a pure mineral sunscreen, using Zinc Oxide as its only filter. That suits those who prefer all-mineral formulas, though SPF 20 gives only moderate protection.
