Ingredients Side-by-side

Helps fight Acne Non-Reef-Safe
Zinc Oxide is a mineral broad-spectrum UV filter; it is the broadest UVA and UVB reflector approved by the FDA. While it is most commonly man-made for cosmetics, it can naturally occur in zincite, a rare mineral.
Dimethicone is a silicone used for making products smooth and silky. It also has the added benefit of sealing in hydration. The amount of dimethicone found in beauty products is considered safe and non-comedogenic, meaning it won't clog pores.

just ok
Slightly more drying, irritating, clogging, and expensive(lol) than my current US drugstore mineral favorite - Banana Boat Baby/Sensitive. Despite a lovely, runny texture still leaves almost as much of a white cast on my white/fair-toned skin than BBB which is classically thick & goopy stuff - both are likely incompatible with darker skin tones unfortunately. FA safe and overall probably better option for fungal acne sufferers than most other US drugstore sunscreens, but at less than half the price, a bigger tube, and a formula that works slightly better for my skin, I'll stick with BBB going forward 'til I have more time to research chemical filters. Good luck in your search!
