Cell phones are essential. But that blue light shining on your skin? Not so much. That’s because research is finding that screens – like your cell phone – emit blue light and this can lead to skin aging – and fast! So, even though we’re all focused on avoiding the sun and wearing sunscreen, it’s time to think about cell phone use and how it can damage skin, too.
Just consider this study published in the Oxidative Medicine and Cellular Longevity journal. Researchers found that high doses of blue light can decrease the amount of carotenoids in skin. This in turn suggests the proliferation of free radicals, which can wreak havoc on skin health.
No thanks, right?
But let’s rewind for a moment. What are carotenoids and what is blue light?
Blue light is a high energy visible light, or HEV light. Sources of blue light are digital screens, LED and fluorescent lights, and even the sun.
What about carotenoids? According to Dr. Joshua Axe, DNM, DC, CNS, carotenoids are fat-soluble nutrients, available in foods like carrots, sweet potatoes, squash and tomatoes.
There are different types of carotenoids, but they all help to battle free radicals, while also providing top antioxidants. In particular, carotenoids help prevent early aging, like wrinkles, dryness, scaly skin and more.
The problem with cell phone use is that it increases the skin’s exposure to blue light radiation, which decreases the amount of carotenoids are skin so desperately needs.
So, to keep your skin looking youthful and fresh, consider cutting back on screen time and even applying a skin protectant for blue light.
