You might want to put your phone down if you’re reading this in bed.
(Harper’s Bazaar) By now we’ve learned to protect ourselves from the sun’s harmful UV rays with daily sunscreen use.
But there’s another form of light that can also damage our skin: blue light.
What exactly is blue light?
Formally known as High Energy Lift (HEV), it’s a wavelength of light not only found in daylight, but also the light emitting from the screens on our phones, TVs, tablets, and computers.
“Blue light technically encompasses certain wavelengths of the visible light spectrum — not ultraviolet radiation,” says Adam Friedman, M.D., an associate professor of dermatology and residency program director of George Washington School of Medicine and Health Sciences.
It’s arguably the type of light we’re most exposed to.
Between emails, texts, social media, and the occasional phone call, we’re pretty much always either staring at a computer screen or a smartphone.
At the forefront of research on skin’s circadian rhythm and skin cell repair, Estée Lauder continues to study factors that cause skin cells to become “out-of-sync”, including the influence of nighttime blue light.
