When I was at the shore recently, Kelly asked what the sunscreen was that my Derm recommended

The Doc said that sunscreen should include Zinc Oxide or Titanium Dioxide.

I asked her why the popular brands do not include these ingredients. She said it was because they are too expensive. She provided me with two different brands:

Vanicream contains both ingredients

Solbar Zinc has 7.5% zinc
