In reply to R. R, Skinceuticals uses it, I believe.

Hi Gio!
Do you have any product recommendations for nano zinc oxide sunscreen?

In reply to Olga. Olga, no uncoated zinc oxide won't penetrate your skin. Zinc oxide needs to stay on the skin to work anyway. If it penetrated your skin, your sunscreen would be useless!

Hello,
so, is it safe to use the Badger sunscreen that uses Non-Nano Uncoated Zinc Oxide? Will that stay on the surface of your skin and won’t penetrate to your bloodstream?
Thank you so much for advise!
Olga.

In reply to Hannah. Hannah, that's a good point. But I think there are ways to formula a broad spectrum sunscreen with nano zinc oxide. One study I read recommended to mix different size particles of zinc oxide so as to have a formula that's effective but doesn't leave a white cast behind.

Ya-TOTALLY! And if it did get into the skin your body would treat nano zinc chances are just like a zinc supplement. Cannot name the study,but I remember it involved a petri dish.

The one thing I’m disappointed about,though,is that the smaller the particle size the smaller the UVA protection,but it does increase the UVB protection.But who really cares,though, about UVB when they’re inside all day? UVB doesn’t go through windows.
