Vanicream's whole approach is subtraction, and it works here the same way it does in their moisturizer.
Zinc oxide is the only active. No chemical filters at all. For skin that stings and flushes when it meets a chemical sunscreen, that removes the most likely culprit in one move.
19.5% zinc is a lot — most facial mineral sunscreens sit between 5% and 15%. You are getting a genuinely substantial mineral filter load.
Five ceramides are along for the ride. Ceramides are the lipids that hold your skin barrier together, so this moisturizes and repairs while it protects.
And it costs about $16. Most mineral sunscreens this clean cost three times more.
