Why does it say +/- iron oxides for some of the Miessence cosmetics?
The “+/-” indicates “more of / less than” iron oxides. For example, the foundations are all basically the same formula but as the product gets darker (from porcelain through to almond) there are ‘more of’ the iron oxides that give the product its colour. Why do you use zinc oxide, iron oxide and mica in your products and what are the health concerns and side effects of these products if any? We use minerals to provide coverage and colour in our cosmetics. There are no relevant health concerns if the products are used for their intended purpose. Zinc oxide, iron oxides and mica are claimed to be harmful to the immune system, respiratory system and reproductive system if they are ingested. But if we use some common sense…. they are similar to crushed rocks. If you eat them, they will cause damage and pain. As would eating any rock particles! Respiratory damage can occur in industrial situations where workers are exposed to massive amounts of particulate matter in the air they breathe.
