Walk around the skincare section of supermarkets and you’ll find it hard to see beauty products that have no titanium dioxide in it. Lotion, soap, sunscreen, whitening cream—you name it. But some people would find it harder to believe that a mined mineral-sounding thing does exist in skin care products. Titanium dioxide, also known as titanium (IV) oxide or titania, is a natural oxide of titanium. It is sourced from various minerals like ilmenite, anatase, and rutile.
