Is too much “screen time” affecting my skin?

October 29, 2014 / 4:03 pm

Smart phone, tablet, laptop, TV: does all this technology affect your skin? We interact with these gadgets for hours every day, often at very close proximity to the delicate skin on our face.

We know about the dangerous effects of UVA and UVB light from the sun, but what about the HEV rays from our electronics?

Recent scientific evidence suggests that High Energy Visible (HEV) light at the wavelengths that the eye perceives as blue to violet is harmful to skin when exposed for long periods of time. The result is what is becoming known as an “HEV burn” and can accelerate the signs of aging.

HEV light has been shown to generate the same amount of free radicals in the skin as those produced by UVA and UVB combined. Like UVA, HEV light does not generate the immediate visible “burn” triggered by UVB, but it may accelerate photoaging. While the effect of UVB radiation is associated with direct damage to the DNA, the cellular damage caused by HEV radiation is less direct and is associated with the generation of free radicals and the induction of oxidative stress.

How do I protect my skin fro HEV damage? The good news is, you probably already are!

Antioxidants designed to prevent UVA damage do double duty to prevent HEV damage so products like Antioxidant Therapy and Daily Therapy have you covered. The big shift in the industry is to start recommending these products be used more often and at a younger age than we previously thought.
