Non-Nano Zinc Oxide

What is non-nano zinc oxide and can it be a natural SPF product which does not require OTC?

Are there any natural SPF products which can have a claim of natural SPF without OTC?

    Sunscreens are OTCs so no, you can't make an SPF claim without following the Sunscreen monograph.
  • In Australia you can use up to SPF15 as a Secondary Sunscreen & you don’t have to go through all the drama.
