CoTZ has a sunblock...Active ingredients: titanium dioxide (8%), zinc oxide (3.8%
Is this to much zinc oxide in this product to use over copper peptites.

That looks OK.

Just put a layer of a copper peptide product below the sunscreen.

I was doing a research and found a sunblock with these ingredients,,,: Octinoxate 7.50%, Octisalate 5.00%, Octocrylene 2.00%, Avobenzone 2.00%...I know avobenzone is not a good choice, is the other ingredients acceptable.

I consider all of these sunscreens as toxic.
