What Are Iron Oxides?

Iron oxides definition

 

You guessed it: iron oxides are compounds made of iron and oxygen. There are many varieties of iron oxides, with the most well-known being rust - but don't worry, your bronzing drops don’t contain rust. In nature, iron oxide compounds are formed by natural geological processes, but iron oxides in skincare are typically synthetic.

They are free of impurities typically found in the iron oxides formed in nature. These carefully crafted synthetic versions ensure consistent quality and safety for skincare products.

How Are Iron Oxides Used in Skincare?

Iron oxides are mainly used in skincare and cosmetic products for their pigments, as they provide a wide range of colors, including yellow, red, brown, and black. They are often essential in formulas for:

  • Foundations
  • Concealers
  • Tinted moisturizers

In these products, iron oxides help create skin-matching shades while offering long-lasting coverage for skin imperfections. Iron oxides are also effective at blocking HEV (or blue) light and enhance overall sun protection when combined with other sun-blocking ingredients.

6 Iron Oxide Skin Benefits

Here are just a few of the reasons you might want to use skincare with iron oxides in it:

Enhanced sun protection

Iron oxides are complementary to ingredients like zinc oxide and titanium dioxide, and when used in combination, they strengthen each other and provide enhanced protection against sunburn

Iron oxide can fill in the gaps where other sunscreen ingredients might be less effective, especially in the visible light spectrum.

Protection against visible light and blue (HEV) light

In a screen-heavy world, we can rejoice that we have ingredients like iron oxide because they help protect skin from high-energy visible (HEV) light, also known as blue light, which is emitted by laptops, tablets, etc. 

This blue (HEV) light can contribute to skin damage and aging, but iron oxides are able to absorb, scatter, and reflect visible light, providing additional photoprotection beyond just UV filters.

Tinting & pigment

Iron oxide's widespread presence in skincare products is often due to the pigments they provide. You'll find iron oxide for skin used in all kinds of foundations, concealers, and tinted sunscreens.

They're especially helpful for reducing the white cast often left by mineral sunscreens. The range of colors available from iron oxides allows for a wide variety of skin-matching shades, making them invaluable in the cosmetics industry.

Prevention of hyperpigmentation

Iron oxides can reduce transmission of visible light by 90% and can protect patients from hyperpigmentation–especially in individuals with darker skin tones–when blended with mineral sunscreens. 

They’re also great for treating and preventing melasma and other hyperpigmentation. This makes iron oxide-containing products particularly valuable for those with a history of or susceptibility to pigmentation issues.

Non-comedogenic 

Iron oxides are non-comedogenic, meaning they won't clog pores or cause breakouts, which makes them suitable for acne-prone skin. This property is crucial for those who need sun protection but are wary of using products that might exacerbate skin congestion or acne.

Sensitive skin friendly

Iron oxides are generally well-tolerated by most skin types and considered safe for use in cosmetics and skincare products. Their gentle nature makes them an excellent choice for those with sensitive or reactive skin who might struggle with other sun protection ingredients.

Note that if you have sensitive skin or have never used a product including iron oxide before, you may want to patch test it before applying it all over.

Using Iron Oxide in Sunscreen to Protect Your Skin

Iron oxide is leveling up your sunscreen with qualities that can help your skin look its best in the present and years down the road. Above and beyond the benefits discussed above, we know it’s great for reducing the white cast that mineral sunscreens can leave on your skin and adding a nice pigment for cosmetic purposes. If you’re guilty of not wearing sunscreen because you don’t want to risk the ghostly mineral white cast, it’s time to give a sunscreen with iron oxide a try.

By choosing a sunscreen with iron oxides, you’re not just protecting yourself from UV rays; you’re getting all-around defense against different types of light damage while helping to keep your skin happy and healthy.
