How Does Blue Light Impact Your Skin?
If you are someone who roams around with their phone in the face then my friend, your skin is highly likely to be affected by a silent enemy. This enemy slowly but scarily affects your skin and shows its effects in the long run. We are talking about the impact of blue light on your skin.

What is blue light?
Light is a form of energy that makes things visible. It has a spectrum depending upon its intensity. Blue light falls in the high intensity category and is only slightly less strong than the UV rays. We are aware of the damage done by the sun’s ultraviolet rays and blue light comes only a small step below it. Pretty scary, right?
Where does blue light come from?
When it is so scary for your skin, you would want to stop using it altogether. To do that, you must know where it comes from? Blue light comes from LEDs (Light Emitting Diodes) These are in the display of our mobile screen, laptop screen and also ceiling lights that make our room bright.
You see when blue light is all around us it is quite tough to stop using it. But the question is, when it is so bad for us why do we use it? Have we been using it since the beginning? What are the alternatives to it? And how does it exactly harm the skin? These must be some of the questions that you must be wondering. We will answer them in this blog for you.
If you remember your childhood, there were no phones, no laptops, no LED lights in our day to day lives which is why there was no awareness of the impact of blue light on the skin. But now, all of us not only have a phone or laptop but are constantly glued to it. Earlier, we did not have tube lights or LEDs bulbs either on the ceiling. We used halogen bulbs that did not emit such harmful rays. So, what went wrong? Did we take a wrong turn in the race towards modernization? Perhaps.
It is clear that we have not been using blue light emitting devices since the beginning of the time. Maybe a couple decades back, we were in a better place. But now that we are aware of the harms of blue light, what are the alternatives for it and what are the steps being taken to prevent this harm?
As you must have noticed, people nowadays wear zero powered glasses or get their spectacles filmed with a blue light filter. It saves their eyes from the harms of blue light. Similarly, you must have seen that there is an increase in advertising on different shades of room lighting, ranging from soft white, warm white, day light to bright white.
Journal of Cosmetic Dermatology research suggests blue light from electronic gadgets can cause changes in your skin cells, including cell shrinkage and death. These hasten the ageing process. Even 60 minutes of screen time is enough to cause these kinds of changes in the skin cells.
