With most parts of the world now in lockdown as the fight against COVID-19 intensifies, many people are spending a considerable amount of time in front of screens either on smartphones, laptops, or smart TVs. In fact, reports from Facebook showed that a 70% increase was recorded across Facebook, Instagram, and WhatsApp since the outbreak of COVID-19. To the shock of many people, the blue light from the electric devices does not only do harm to the eyes but also plays a role in skin damage. Yes, the blue light from smartphones, laptops, and TV screens is harmful to your skin. That must sound scary.
So what is this Blue Light?
Blue light, also known as Artificial Visible Light (AVL) or High Energy Visible Light (HEVL), represents part of the spectrum of visible light that features high energy and short-wavelength light between 380 and 400 nm. Its high-energy property enables it to penetrate deep into the skin.
The main source of blue light that we are exposed to is the sun. Aside from being the source of infrared light, the sun is also the largest producer of blue light, which is what gives a clear sky the blue colour. The digital devices produce only a fraction of blue light compared to the sun. The only significant difference is that digital devices are so much closer to us than the sun.
The blue spectrum of light is very close in wavelength to UV light. Both blue light and UV light have some things in common such as short wavelengths. High amounts or frequent exposure to blue light can cause damages to the deep layers of the skin, which results in skin conditions like skin cancer and photo-aging.
Effects of Blue Light (This is not the same as Blue Photon LED Light)
Photo-aging refers to the aging of the skin as a result of harsh light. Blue light from the digital devices plays a significant role in aging your skin. According to experts, constant exposure to blue light can stimulate oxidative stress in live skin. This significantly contributes to premature skin aging, similar to the one caused by exposure to UV rays.
Blue light also penetrates deeper into the skin. Experts state that it can penetrate all the way to the dermis, where collagen and elastin are found. The blue light interferes with collagen production, which results in loss of skin firmness leading to wrinkles and visible lines on the skin.
Another way that blue light causes premature skin aging is by causing skin pigmentation. Studies have shown that blue light is more active in inducing skin pigmentation than UV light.
Blue light also interferes with one’s sleeping schedule. Research has shown that blue light does this by altering with the natural circadian rhythm. People exposed to high amounts of blue light at night often have difficulty sleeping. This happens because blue light affects the levels of the sleep hormone, known as melatonin.
3. Increased risk of macular degeneration
The high energy in blue light enables it to easily penetrate the eyes up to the retina, consequently damaging the light-sensitive cells located in the retina. This leads to changes that interfere with the strength of the eyesight/blurred vision, similar to those of macular degeneration. This consequently increases one's risk of suffering from macular degeneration later in life.
Blue light (from mobile devices) vs Blue Photon LED Light (from Skin Clinics)
Artificial Visible light differs from blue photon LED light we see in skin clinics in several ways. First, blue photon LED light is natural, while blue light from digital devices is artificially generated. That explains why blue photon LED light comes with loads of benefits to the skin, whereas artificial visible light causes only harmful impacts on the skin.
Secondly, the blue LED light used at skin clinics has short wavelengths of between 460nm to 490nm, which is relatively longer than the artificial visible light whose wavelengths range between 380nm to 400nm.
Lastly, artificial visible light features wavelengths with significantly high energy as compared to blue LED light. The high energy in blue light is the reason behind its ability to penetrate deep in the skin and its destructive nature.
How to protect yourself from blue light
Despite the blue light having harmful effects on the skin and eyes, the good thing is that there is a way to protect yourself from the destructive light.
The easiest thing you can do is download FLUX onto your devices. FLUX adds a orange tint to your screen which removes the blue hue. At first you will think your screen is too orange, but trust me after a couple of days your eyes will adjust and you wont notice the orange anymore. You can also adjust the levels to be less orange or more. After using FLUX on my devices for a while, I recall a time where I turned it off, and once I did I saw how my screen was overbearingly blue! I havent noticed the blue before as my eyesight has been used to it.
Try FLUX for yourself, and for your health! Download here.
If you can already witness the harm done to your skin by the harmful artificial visible light, don’t worry. You still have a chance to reverse those effects. You can reverse the effects of blue light by countering it with natural blue or red LED light therapy. With photon LED light gaining popularity in the recent years, now you have the option to buy a light therapy device and treat your skin yourself at home. Remember when you are looking for a device to do your own research. Make sure it is a FDA-Approved Medical Device, as you don't want to risk damaging your skin with cheap models. Skin Engineers have blue and red light therapy devices designed for home use. They are FDA-Approved and rated Class 1 medical device, which means they are rated the safest class available.
