About this sunscreen
Functionalab Mineral Sunblock SPF 30 is a 100% mineral sunscreen built on zinc oxide and titanium dioxide, so it relies on physical filters rather than chemical ones. It leaves a dewy finish and feels lightweight on skin, with low sting and low pore-clogging potential, though the white cast is moderate as is common with mineral formulas. Sun protection is good for everyday wear, and the finish layers under makeup okay rather than perfectly. With a score of 73.3/100 it is a solid daily mineral option for those who prefer physical filters.

Does Functionalab Mineral Sunblock SPF 30 leave a white cast?
It can leave a moderate white cast, which is common for 100% mineral sunscreens built on zinc oxide and titanium dioxide. The dewy finish helps soften the look, but a slight tint may show on deeper skin tones.
Is the Functionalab Mineral Sunblock SPF 30 mineral or chemical?
It is fully mineral, using zinc oxide and titanium dioxide as physical filters with no chemical UV filters. That makes it a good choice for those who prefer mineral-only formulas.
Is Functionalab Mineral Sunblock SPF 30 good for acne-prone skin?
It has low pore-clogging potential and low sting, so it is generally friendly for breakout-prone skin. The dewy finish may suit normal to dry skin more than very oily skin.
