The Wrinkly Truth Behind Your Cell Phone

Cellphones cast blue light. But, what’s blue light? 

You see, it’s a fancy word for a high-energy wavelength that you can see (400-500 nm).  A bit of physics before getting to the wrinkly point. It’s a wave almost as short as UVA light (315-400 nm). Dubbed A for aging and we all know by now what that does to our skin, which is why we have to wear sunscreen.

Cell phones are not the only ones that shine bright with blue light, the sun is our main source, but other LED electronics also contribute… and that’s where we spend about 13 hours a day (according to a 2020 Nielsen report).

How do we know that blue light can age us?

Well, a 2018 study showed how random subjects were exposed to an iPhone for an hour and they found an increase in free radicals (that is: oxidative stress at a cellular level that leads to wrinkling and other age-related skin concerns). 

So how do we protect ourselves?

Look for sunscreens that read BROAD SPECTRUM, BLUE LIGHT and HEV-IS, designed specifically to protect us from blue light.
