Is COSRX Aloe Soothing Sun Cream good for sensitive or oily skin?
It is generally gentle. The aloe base and low sting risk suit sensitive skin, while the matte, lightweight finish and low pore-clogging risk suit oily skin.
Does the COSRX Aloe Soothing Sun Cream Spf50+ leave a white cast?
No, white cast is low. It dries to a matte finish that sinks into the skin without a visible film.
Is it mineral or chemical?
It is a hybrid, mostly chemical with a touch of titanium dioxide, using filters like octinoxate, Tinosorb S, Ensulizole and Amiloxate.
