Blue light has become an increasingly more familiarised antagonist in recent years with many touting its detrimental effects on the skin. Blue light is part of the natural emitted visible light in the electromagnetic spectrum with a major source of emission being our sun, which, moving into the warmer months, bears down with a certain ferocity that shouldn’t be ignored. Other known emitters of blue light are LED lights, fluorescent lights, and perhaps the most insidious of them all, digital screens such as our phones and computers.
Our digital screens at some point made the subtle shift from casual appliance to tool of necessity with barely one among us not daily-using our screens for work, play or some combination of the two. The emitted blue light from our screens is comparatively minimal to that of the suns, however compounded usage does come at a cost. Recent studies show that the blue light emitted from the sun, and in deed our screens, can lead to DNA damage, cell damage, skin barrier damage, and photoaging.
