Did you know your sunscreen may be doing worse damage than the sun?
Many brand name sunscreens offer “natural” sunscreens, but even the natural and organic sun blocking lotions contain chemicals that are leaking into your bloodstream.
Some researchers even say that topical toxins are more harmful than ingesting them as your skin provides easier access for toxins to be absorbed straight into the bloodstream.
What’s In Your Sunscreen
Aluminum is just the beginning to the horrors of this summer sunblock-buster. It’s really not even our main concern, though aluminum poses a giant health risk.
There are two different methods to blocking sun rays from the skin found in most sunscreens. The first is through organic, or carbon-based, filters, and the second is with inorganic filters.
These UV filters are easily absorbed into your skin. The most commonly used organic UV filter is oxybenzone which has been found in urine and breast milk samples after a study was done on the human application of full-body sunscreen.
The study was completed in 2004 and found 96% of urine samples to carry oxybenzone, which has been linked to sperm abnormality in mice. Another study in Switzerland shows that other UV filters have appeared in 85% of breast milk samples.
The most concerning fact on organic filters is that they’re unstable when exposed to UV radiation. So the stuff it’s supposedly protecting you from is actually weakening the filter. To top it off, some filters become completely useless once soaked through the top layers of skin and increase your risk of cancer.
These filters are commonly made using nanoparticles of titanium dioxide or zinc oxide. While the lesser of the evils, inorganic filters can form reactive oxygen species, including free radicals, and have been shown to damage human cells in one 2012 study.
Inorganic filters have not been shown to penetrate the skin as easily as organic filters do. But studies have shown that this could change if we remove the top layers of dead skin cells, like after we shave or exfoliate.
So to be on the safe side, it’s suggested to avoid inorganic filters when other options are available.
Alternative To Sunscreen
The healthiest option is to increase your tolerance to sun exposure. Covering up or finding shade is the easiest way to avoid getting sunburn. Dietary changes, such as increasing your intake of antioxidants, can also protect your skin from sun damage.
But let’s face it; we need to be out in the sun during the summer! In fact, most of us want to soak up the sun.
In this case, using a non-nano zinc oxide sunscreen is the best option. It contains larger particles than other filters that are too big to be absorbed into the skin and bloodstream.
