The Best Mineral Sunscreens With Antioxidants.

In terms of anti-aging products available on the market, sunscreens are by far the most effective and affordable treatment – yet they still remain overlooked. Without incorporating sunscreen into your daily skincare routine you are fighting a losing battle. But what about protection from visible light? Well, that’s where mineral sunscreens with antioxidants come in!

Sunscreens protect against ultraviolet (UV) radiation and the associated DNA-damaging effects of free radicals. In addition, sunscreens prevent the breakdown of collagen and elastin in the skin caused by overexposure to UV radiation. In fact, overexposure to UV radiation is the number one contributing factor to premature skin aging.

Premature Aging Vs Natural Aging

Premature skin aging is different from the natural chronological skin aging process. As we naturally age, we lose some of the fat padding in our faces which results in fine lines and thinning skin but naturally aged skin tends to remain smooth and unblemished.

Prematurely aged skin, however, is characterized by deeper wrinkles, hyperpigmentation, and dry and leathery skin. This is due to the break down of collagen and elastin mentioned earlier.

Preventing Premature Aging

A large amount of research has demonstrated that sunscreen can prevent this premature aging process.

For example, one study had patients apply a broad-spectrum sunscreen daily for four years and compared the effects to a control group who were instructed to practice their usual sunscreen habits. After the four-year study period, the patients who applied a broad-spectrum sunscreen daily appeared younger than the control group. In fact, even more impressively, there were no detectable signs of skin aging during this period [1].

So, if sunscreen is so effective on its own, what’s the point of mineral sunscreens with antioxidants?

What’s The Point Of Mineral Sunscreens With Antioxidants?

Well, there are two main reasons that mineral sunscreens with antioxidants are better than conventional sunscreen:

  1. No sunscreen can protect skin from 100% of UV radiation. (SPF30 protects against 97% of UVB rays, while SPF50 protects against 98% of UVB rays). The additional protection offered by any sunscreen above SPF50 is minimal – this is why sunscreens cannot be advertised as anything more than SPF 50+ in Europe. The common misconception is that SPF 60 would offer double the protection of SPF 30, however, this is not the case. The only benefit is that higher SPFs usually have higher UVA protection due to the PPD method that recommends a UVA:UVB ratio of 1:3 (aka. a SPF30 sunscreen should have a PPD rating of 10).
  2. While UV radiation is the most damaging source of solar radiation, it accounts for only about 3-7% of total solar radiation. Solar radiation consists of mainly 53% infrared radiation (780-5000nm), 39-44% visible light (400-780nm), and 3-7% UV radiation (290-400nm).

This is where mineral sunscreens with antioxidants come in.

Skin Damage Caused By Visible Light

Firstly, 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. However, even very thick mineral sunscreens (increasing the thickness increases their ability to reflect light from the skin) are unable to offer adequate protection against visible light unless they also contain iron oxide and/or antioxidants [2].

Blue light is generally the most damaging wavelength of visible light due to the fact that photons in this wavelength have higher energy. Excessive exposure to blue light can lead to skin cell abnormalities as well as cell death [3].

Visible light can lead to the production of DNA-damaging free radicals in a similar way to UV radiation. In fact, in one study, visible light accounted for 33% of free radical production in solar irradiated skin. This was in comparison to 67% of free radical production that was attributed to UV radiation [4].

Basically, visible light can cause half the amount of free radical production as UV exposure.

How To Protect Skin From Visible Light

Antioxidants protect against visible light in the same way that they protect against infrared and UV radiation – by neutralizing DNA-damaging free radicals.

In fact, the addition of antioxidants to sunscreen can reduce free radical production from visible light by up to 78%. Furthermore, antioxidants on their own, without sunscreen, can reduce the number of free radicals produces in a similar way [5].

Some antioxidants that have been scientifically proven to protect against free radical production from solar radiation include; Vitamin C, Vitamin E, (particularly Vitamin C&E in combination), and EGCG (the major polyphenol in green tea).
