If you are using anything other than titanium and zinc, you need to apply the sunscreen every two hours-because sunscreens degrade with light and heat. They also bring reactive oxygen species type free radicals (ros) below the surface of your skin and do more harm than help. Higher SPF will not make a difference. Also, Meroxyl is a potential tetrogen (meaning it will be found in trace amounts in your ovum and has the potential for birth defects) and a potential carcinogen-which is why the FDA was reticent to approve it.

I'm using Blue Lizard Suncream. It's noncomedogenic and it costs twelve fifty for a bottle-and there are no harmful chemicals in it.
