About this sunscreen
Maruderm SPF 50+ Mineral Filter Sun Cream is a pure mineral sunscreen based on Zinc Oxide. As an all-mineral formula it carries a higher chance of visible white cast and is rated poor as a makeup base, but it has a balanced finish, is generally non-stinging, and is low for pore-clogging. With a 69.1/100 score and only moderate measured protection, it is a basic mineral option rather than a standout.

Does Maruderm SPF 50+ Mineral Sun Cream leave a white cast?
White cast is rated high. As an all-mineral Zinc Oxide formula it can leave a visible cast, so blend it well and consider it best on lighter skin tones.
Does the Maruderm SPF 50+ Mineral Filter Sun Cream work under makeup?
It is rated poor as a makeup base, so it is better worn on its own than layered under foundation. It does have a balanced finish and is generally non-stinging.
Is it mineral or chemical, and is it good?
It is a pure mineral sunscreen using Zinc Oxide. It scores 69.1/100 with moderate measured protection, a basic mineral option.
