This study investigated the structure and size of particles of iron oxides which provide shade to the skin among the elements of blemish balm cream, which is recently stirring up a boom in the cosmetic market. We observed that the rod-shaped particles of iron oxide red are dispersed in lumpy form. Under a high magnification scanning electron microscopy, we observed that the rod-shaped iron oxide red 500~600 nm in length and the cubic-shaped iron oxide red 100 nm in length are dispersed. The particles of iron oxide yellow were in a form of rod and their length was measured as 300~600 nm. The particles of iron oxide black formed irregular masses and were in a spherical form and their diameter was measured as 200~300 nm. When the results of analyzing the elements of iron oxide red using an energy dispersive X-ray spectroscopy were converted into a percentage, the components of Fe and O was 74.66% and 25.34%, respectively. For iron oxide yellow, the components of Fe and O was 75.00% and 25.00% and for iron oxide black, the components of Fe and O was 84.78% and 15.22%, respectively. As a result, it was found that iron oxide red, iron oxide yellow and iron oxide black, as one of the ingredients of cosmetics, were fine particles which made up of the element of Fe and O with no impurities.
