Thank you so much for introducing to us the knowledge about natural mineral sunscreens. I can’t wait to give them a try. But my concern is if they are too greasy for oily and acne-prone skin?

Good info not many people know, and not only that – Physical sunblock protects until it is washed off, unlike chemichal sunscreen which breaks down after about an hour, which is why they say to reapply after 1 hour of wearing!

Good Question. I would think that if there are chemicals in the formula, then it is not just a physical sunscreen. But it might depend on what the chemical ingredients are. Do they block the sun, or are the inert minerals what is protecting you from the sun? I will pose this question to a group I belong to, and I will see if they have the correct answer

Thank you for this info. Can you please clarify further – if a sunscreen contains titanium dioxide and/or zinc oxide *and* chemical components in the active ingredients, is it still considered to be a physical sunscreen? Thanks!
