Iron oxides as colorants in makeup (makeup otherwise would not be capable of exuding color) are put through stringent processes to purify them: It is our belief that iron oxides, when as pure as they can get, are the safest FDA-approved colorant.

Iron oxides are made in a lab for safety assurance; in the case of iron oxides, those found in nature often contain impurities, contaminated with heavy metals like arsenic, mercury, cadmium, and nickel. This is an example of natural not always being safer--the lab-produced variety are the way to go in the case of the safest colorant option for cosmetics. Without iron oxides, makeup would have no color. They are rated non-toxic and the choice colorant go-to for the safest cosmetics. Iron oxides are known to be gentle and aren’t known to be allergenic. Other makeup, even mineral makeup ingredients that they're formulated alongside with, could be causing someone irritation, though.

With iron oxides, we source those of which are not nanoparticle or even micronized in size. Most suppliers or iron oxides provide them in micronized and nanoparticle size, which is another beast in of itself.

In the case of coloring makeup, it is our research-driven belief that lab-created and -tested non-nanoparticle iron oxides are the best way to color makeup.
