Should We Wear Sunscreen To Protect Our Skin From Blue Light Damage?
As if you needed another reason to put down your phone, it turns out the blue light emitted by your cellphone and computer screens can not only make it harder to fall asleep at night, it could be damaging your skin, too.
Blue light, the kind emitted from screens, is a type of high energy visible light, or HEV. While blue light is strongest from environmental sources like the sun, there are studies that show electronic screens can have similar effects.
“Blue light causes a slightly different type of damage. It causes generation of reactive oxygen species which damages collagen, causes wrinkling, pigment changes and laxity,” said Michele Farber, a dermatologist at Schweiger Dermatology Group in New York. The sun, on the other hand, causes photoaging to a greater degree than blue light, and can also induce skin cancers, she said.
