Is iS Clinical Extreme Protect good under makeup?
No, it is rated poorly as a makeup base, so it may not layer smoothly under foundation. It works better worn on its own.
Is the iS Clinical Extreme Protect SPF 30 mineral or chemical?
It is a hybrid, using the mineral filter Zinc Oxide alongside the chemical filter Octinoxate.
Is it good for acne-prone skin?
It has a balanced finish and a low pore-clogging profile, so it is generally fine for acne-prone skin. With a score of 72.5/100 it is solidly above average overall.
