Addicted to Your Phone? Blue Light From Digital Devices May Be Damaging Your Skin
Michela Marra | Friday June 29th 2018
How much time do you spend in front of your computer, tablet or smartphone? Probably a lot, even too much. I made a quick calculation and more than half of my day flies by responding to emails, writing on my computer, watching videos on YouTube or catching up with my favorite TV series. All done rigorously in front of a screen. In my case, there is no way out. I am continuously exposed to the notorious blue light, given off from the screens of all our electronic devices that, as shown in many recent studies, can contribute to skin photoaging.
It’s useless to deny it, we live daily immersed in an invisible sea of electronic pollution that can undermine the health of our skin just as much as solar radiation. And the difference? We don’t see the consequences directly with blue light; as opposed to the sun, when we are exposed without the right protection we can feel the tightness of our skin. In the case of blue light, however, its harmful effect is not minimally perceived, but it exists. Let me explain to you how it works.
First of all, what is blue light? And where does it come from? It is a natural component of solar radiation and is part of visible light (ranging from 400 nanometers to 500 nanometers). A part of blue light comes from the sun: it penetrates the atmosphere and reaches us with a constant and relatively weak intensity, with some beneficial effects. The artificial kind of blue light comes from screens, all the light given off from LED and from our devices that generates an intensity up to 1000 times higher than the threshold of visual comfort, and therefore can have harmful consequences. Like I said before, it is less dangerous than UV rays, because it does not have visible effects during exposure, but we are constantly exposed.
Although it is characterized by a longer wavelength than UV – thus it is less energetic, because it has a weaker intensity than ultraviolet rays – in fact it penetrates deep into your eyes and skin. Considerable exposure to blue light can alter the circadian cycle, causing fatigue and vision problems (for example, macular degeneration) and as far as the skin, it accelerates oxidative stress, damaging the skin’s protective functions. Fortunately for our eyes, the solution is at our fingertips, thanks to glasses with anti-glare filters for blue light. What about the skin? Until now, there is not much, but new challenges are on the table for cosmetic companies (and some have already taken advantage).
So what should we do? I wanted to investigate a bit deeper about blue light, together with the French brand Uriage, I was curious to test the level of my exposure. It went better than I would hope, according to the analysis, I am attentive to my skin’s health – mostly because I do not smoke or drink. My attitude towards skincare is rather “green”, even if my life is frenetic and I am addicted to technology. Will it be enough to program a digital detox on the weekends to better myself? Not exactly, because skincare should be based on a precise beauty routine (as always).
Here are some new products to sneak into your beauty case to combat these new enemies to our skin. If you are also living the digital life, follow my suggestions.
A thermal water base by Uriage, this new line limits the harmful due to the exposure to blue light. Thanks to the patent Blb and Filmexel and to a complex of anti-pollution actives that creates a “second skin” on the surface, in order to avoid fine particles adhering to the epidermis. The line is made up of seven products: three day treatments (multi-action cream for normal to dry skin, multi-action cream with SPF 30 for normal to dry skin and multi-action fluid for normal or combination skin); two night treatments (Multi-action Detox Night Cream for all types of skin and Multi-action Peeling Night Cream for all types of skin); two specific treatments (Multi-action Intensive Serum for all types of skin and Multi-action Eye Cream for all types of skin).

This cream improves skin tone by optimizing the production of collagen. It fights the first wrinkles and expression lines (especially for those who spend a lot of time in front of the computer).
It acts as a screen for pollution, blue light and environmental rays thanks to the Environmental Protection Technology. Lightly colored, this cream adapts to all types of skin, homogenizing the complexion and improving brightness, leaving the face toned and compact.
