The Best Mineral Sunscreens With Iron Oxide.

Sunscreen is by far the best anti-aging product available on the market. This is due to the fact that the majority of premature aging is due to overexposure of ultraviolet (UV) radiation. The addition of iron oxide to sunscreens can broaden this protection. So what are the best mineral sunscreens with iron oxide?

UV Radiation

UV radiation leads to the production of DNA-damaging free radicals in the skin, decreases collagen and elastin levels within the skin, and causes changes to skin pigmentation.

Daily application of broad-spectrum sunscreens can significantly reduce this damage by reflecting or absorbing damaging UV rays. In one study, participants who applied sunscreen daily over a four-year period had no detectable signs of skin aging [1].

While UV radiation is the most damaging form of solar radiation for the skin, it only accounts for a small percentage of total solar radiation.

Solar Radiation

Solar radiation that reaches the surface of the earth is composed mainly of infrared radiation (780-5000nm), visible light (400-780nm), and UV radiation (290-400nm). In fact, infrared radiation accounts for about 53% of solar radiation, visible light accounts for about 39-44%, and UV radiation accounts for about 3-7%.

Visible light has demonstrated similar effects to UV radiation in the production of DNA-damaging free radicals and can cause abnormalities in skin cells as well as cell death [2].

So why are we not protecting our skin against visible light? And, more to the point, how can we protect our skin against visible light?

How To Protect Skin Against Visible Light?

There are two main ways that research suggests we can protect our skin from visible light – iron oxide and antioxidants.

Iron Oxide

Iron oxide is not included as an approved sunscreen by the FDA but is often added to mineral sunscreens in order to improve ‘white cast’. In addition, it can broaden the protection offered by mineral sunscreens into the UVA and visible light spectrums.

Some research suggests that the addition of iron oxide to mineral sunscreens can reduce the amount of UVA and visible light transmitted to the skin to 20%. In particular, when iron oxide is combined with zinc oxide, it can reduce the amount of UVA radiation transmitted to the skin to 1.5% [3].

In general, mineral sunscreen ingredients zinc oxide and titanium dioxide are better at protecting the skin from visible light than chemical sunscreens due to the fact that they reflect and scatter light [4].

However, they still do not offer sufficient visible light protection without the addition of iron oxide.

While iron oxide is effective at absorbing all wavelengths of visible light [4], it is particularly effective at absorbing longer UVA radiation and blue light but its effects are less optimal as wavelengths increase [5]. UVA and Blue light (high energy visible – HEV – light) are particularly damaging for skin and adequate protection is not offered from conventional sunscreens [2].

Antioxidants protect against visible light in the same way they help protect against UV radiation – by preventing or reducing the production of DNA-damaging free radicals in the skin.

In one study, the addition of antioxidants to a sunscreen led to a 78% reduction in the number of free radicals produced after irradiation with visible light. Even more impressive, antioxidants alone reduced the amount of free radical damage in a similar way [6].

The Best Mineral Sunscreens With Iron Oxide

Before we go through the best mineral sunscreens with iron oxide, its worth mentioning that whatever sunscreen you decide to use, be it with iron oxide or without, there are some key things to remember:

  • Sunscreen should be broad-spectrum – meaning that it protects against both UVA & UVB rays.
  • Sunscreen should be at least SPF30 – while there isn’t a huge amount of additional UVB protection offered by SPF50+ sunscreens (SPF30 protects against 97% of UVB rays, while SPF50 protects against 98% of UVB rays), there may be better UVA protection in higher SPFs. This is due to the PPD method that recommends a UVA:UVB ratio of 1:3.

Note: Due to iron oxides natural reddish hue, the majority (if not all) of sunscreens containing iron oxide will be tinted.

With that out of the way, here are the best mineral sunscreens with iron oxide…
