Dr. T. and others,
I know that wearing avobenzone and wearing a makeup product with titanium dioxide will weaken and degrade the sun protection on both ends. is this true of all chemical sunscreens? i currently use Meroxyl - la roche posay Anthelios XL Fluide Extreme - spf 50+. I only lightly dust a powder, which has titanium dioxide in it to deal with shine. Will using products with physical blockers weaken meroxyl? And if so, to what extent? It seems impossible to find a makeup product without t.d.

I am not aware of meroxyl reacting with physical blockers, but then again there's not that much data on meroxyl.
