About this sunscreen
Sun Bum Mineral Sunscreen Lotion is a pure mineral SPF 50 built on Zinc Oxide. It has a dewy finish and is unlikely to sting, but it carries a medium white cast, a heavy feel on skin and a higher pore-clogging profile, and rates as a poor makeup base. Protection registers as moderate here; the score of 58.7 reflects a body-oriented mineral lotion that is generally less suited to wear under makeup or on acne-prone facial skin.

Does the Sun Bum Mineral Sunscreen Lotion Spf 50 leave a white cast?
White cast is rated medium, so some cast is likely, which is common for zinc-based lotions. It also has a dewy finish and a heavier feel on skin.
Is the Sun Bum Mineral Sunscreen Lotion Spf 50 good under makeup or for acne-prone skin?
It rates as a poor makeup base and carries a medium pore-clogging profile, so it is generally less suited to wear under makeup or on acne-prone facial skin. It reads more like a body sunscreen.
Is it mineral or chemical?
It is pure mineral, built on Zinc Oxide alone, and is unlikely to sting.
