Iron oxides are cosmetic pigments that originate from natural minerals and are considered both synthetic and mineral when refined. Used to tint sunscreens, create complexion-enhancing makeup shades, and help protect skin from visible light. Iron oxides are considered to be safe as used in cosmetics and personal care products because they are non-toxic and non-allergenic. Iron oxides are well tolerated by those with sensitive skin.

The primary purpose iron oxides serve is purely functional since they play an integral role in the formulation process. However, there's also a secondary, more skincare-focused benefit that makes them one of those 'get extra bang for your buck' ingredients worth seeking out.
Iron oxides are most often used to add pigment to cosmetics and skincare, but they also have the added benefit of protecting the skin from visible and blue light

Most of our products such as the oxides are produced in a laboratory to be naturally identical to those found in nature. The reason for this is that a natural oxide would not fit the FDA requirement for the minimum of heavy metal content. Soils naturally contain heavy metals so any oxide must be purified for cosmetic use. Iron oxides in nature (dirt) are often loaded with toxic metals like lead, arsenic, mercury, antimony and selenium. The FDA stepped in to regulate cosmetic colorants so the level of toxic metal present are present in such low concentrations that they are considered &#;safe.&#; In fact, only synthetically prepared iron oxides are approved for use in cosmetics in the USA. Since Oxides and Ultramarines have been manufactured in labs to assure purity. The lab manufactured pigments have the same molecular structure as their natural identical but without toxins.
