About this sunscreen
Klairs Mid Day Blue UV Shield SPF 50+ PA++++ is a mineral sunscreen using Zinc Oxide as its only UV filter. It dries to a matte, lightweight finish and is low on pore-clogging, and it generally does not sting, though it can show a medium level of white cast typical of zinc. It works okay under makeup. With a score of 69 and moderate protection, it is a decent mattifying mineral choice for those who tolerate some cast.

Does the Klairs Mid Day Blue Uv Shield Spf 50+ Pa++++ leave a white cast?
It can show some. White cast is rated medium, which is typical of a Zinc Oxide mineral formula, so blend it in on deeper skin tones.
Is the Klairs Mid Day Blue Uv Shield Spf 50+ Pa++++ good for oily or acne-prone skin?
Yes, generally. It has a matte, lightweight finish and is low on pore-clogging, so it commonly suits oily and breakout-prone skin.
Is it mineral or chemical?
It is mineral. Zinc Oxide is the only UV filter, with no chemical filters.
