Mica, bismuth oxychloride, titanium dioxide, iron oxide and ultramarine apparently form a mineral make-up, which has reportedly taken cosmetic industry by all its rage. At the outset when cosmetics are going the functional way, mineral make-up is accused of causing all the vengeance it can, on the skin of consumers and to add to it, is the approval of FDA for these minerals.
While there are no specific grudges against titanium oxide, which is known to protect the skin form UVA and UVB, bismuth oxychloride, which is added to give color is synthetically prepared and might contain impurities. Facts provide that mica, iron oxide, bismuth oxychloride are all purified before mixing them into cosmetics.
It is quite dicey to conclude that mineral make-up can be toxic for skin as research shows that most of the minerals are extracted directly from nature, but a monitoring of purification is essential to guarantee that they will not produce toxic effects once they are abrorbed by the skin. Zinc oxide and titanium oxide are already proven as sun blocks, anti-bacterial and moisturizers and it will take time for other minerals to gain acceptance.
