I have to admit it… Lately, between work and free time, I spend all day in front of a screen. If it's not the computer, it's the mobile phone, but I'm always in front of the blue light. However, although these devices can make our lives easier... How does blue light from screens affect our skin?
What is blue light?
You probably know this, but there are many types of light that we are exposed to on a daily basis. In addition, considering that the technological revolution has been simmering for years, our exposure to blue light projected by mobile devices has increased considerably .
However, blue light is not something that has appeared out of nowhere thanks to technology, since the Sun has always transmitted a certain dose to us. Therefore, it is clear that small doses of this type of light are not only harmful to humans, but can also be beneficial . According to several studies, our brain is capable of paying more attention to it, although an excess of blue light can also have negative effects on our body .
What problems can blue light cause our skin?
According to several studies, in Spain we spend an average of almost 4 hours a day in front of the mobile (and, if we talk about young people, this figure is widely exceeded). Therefore, it is 4 hours that we spend in front of blue light and that, apart from affecting melatonin , can cause hyperpigmentation of the skin . (Maybe it sounds like a joke, but it's not...)
Skin hyperpigmentation , although it is a benign condition , causes us to suffer darker spots than the epidermis that surrounds it . All this, as we have commented on some occasion, is a consequence of the melanin that the melanocytes of our dermis can produce .
With blue light, this hyperpigmentation occurs mainly on the forehead and around the eyes. Thus, this fact can also lead to skin aging , creating wrinkles or expression lines on our face , for example.
Surely you knew that the use of mobile devices could affect sleep , but did you know about the side effects of blue light on the skin ? If you want to know more about melanin , keep reading!
