Ever heard of blue light and wondered what it is and where it comes from? If so, then you’re certainly not on your own, as despite it being pretty much everywhere we look, most of us don’t pay it any attention. Nor indeed do most understand why blue light sunscreen is necessary; however, that’s something we seek to resolve here.
Believe it or not, we are all surrounded by blue light, whether we’re out in the midday sun, at home in front of the computer or staring at your smartphone on the train. Pretty much the only place you won’t find blue light is in a darkened room, so it’s important to understand what it is and why blue light protection is needed.
At Blue Lizard Sunscreen, we’re all about helping people to protect themselves and their skin, and in a moment, we’ll get into what blue light exposure can lead to. However, first we’re going to take a look at what blue light is. While many people are aware of the basic principles of visible light, it’s actually quite a complicated concept.
So, What is Blue Light?
Ok, so it’s fairly well-known that sunlight is composed of various frequencies of visible and non-visible light, with ultra-violet rays being responsible for tanning and damaging the skin. What’s not so well known, however, is the amount and complexity of the different frequencies we’re talking about. The truth is that sunscreen for blue light is necessary, as it’s one of the light frequencies that can lead to skin cell damage.
Sunlight actually contains not just blue light, but also red, yellow, green orange and perhaps unsurprisingly, all the colors of the rainbow. The amount of energy contained within a particular frequency range is what results in various different shades. Add all of these frequencies together and you get ‘white light’ or sunlight, to you and me.
What Damage Can Blue Light Cause?
Basically, exposure to the blue light that exists in the sun’s rays is known to result in changes to skin cells, which also include shrinkage and eventual skin cell death. It’s also a light frequency that’s present in the digital devices that are ubiquitous these days, as well as TVs and PC monitors - so essentially, we’re talking about anything with a screen.
These High Energy Visible (HEV) light rays are known to play a part in speeding up the ageing process, so it stands to reason then that sunscreen for blue light should be part of anyone’s shopping list, regardless of the time of year. When you think that blue light can be causing damage to your skin even when the sun’s not even out, you begin to understand why.
Other Negative Impacts of Blue Light
Blue light can also have a damaging impact on the body’s circadian rhythm - something that has dictated our sleep patterns since the dawn of time. In natural daylight, the lower light frequencies become more abundant towards the end of the day, making our bodies create more melatonin - meaning that we naturally feel more sleepy. During the middle of the day, the frequencies are higher, making us more awake.
When we expose ourselves to blue light at unnatural times of the day, our circadian flow can be disrupted and our sleep patterns can become irregular as a result. Spend too long on your phone in the evening and you won’t feel sleepy when you’re meant to due to a lack of melatonin in the brain. Repeat this for just a few days and you can quickly become tired and out of sorts.
Blue light is just a short step away from ultraviolet rays on the electromagnetic spectrum and it’s also associated with serious eye issues like macular degeneration. With this in mind, it becomes obvious that your skin needs to be protected from blue light, making the wearing of blue light sunscreen a wise choice. The good news is that Blue Lizard Sheer Face lotion comes with all the protection you need.
Sheer Face Blue Light Protection
As with all of the reef friendly Blue Lizard sunscreen products, our Sheer Face lotion is created using dermatologist-recommended zinc oxide, but it comes with a difference. This product in particular also contains very specific plant extracts that protect you against the aforementioned blue light and it rubs in clear, so you don’t have to worry about any white residue on your skin’s surface.
In addition to being paraben and fragrance-free, our Sheer Face lotion blue light sunscreen is not only water resistant and sweat resistant for 80 minutes, but also free of Oxybenzone and Octinoxate - the compounds that have been said to potentially cause damage to the delicate and beautiful coral reefs that so much marine life calls home.
Blue Lizard Sheer Lotion for Face moisturizes skin for 24 hours. Containing antioxidants, as well as vitamin E and shea butter, it’s ideal for all types of skin and leaves you skin feeling supported, smooth and healthy. It’s water and sweat resistant, too, for 80 minutes.
Stay Safe & Protected Wherever You Are
As you can see, blue light protection is very much needed and it’s something that’s especially important in the modern digital world with so much blue light around. However, with a bottle of our Sheer Face lotion in your bag, you get the protection you need, wherever you are and whatever you’re doing.
At Blue Lizard Sunscreen, our natural products work far differently than traditional chemical sunscreens that you’ll find on the market. The zinc oxide that they contain sits on top of the skin rather than being absorbed into it and so provides superior protection from UV rays.
We thank you for taking the time to read this article to the end and we hope that after doing so, you get the protection you need against all the visible and non-visible light frequencies that exist. It’s the least your skin deserves and it’s the key to holding on to your supple, youthful-looking skin.
