Our current times are increasingly tethered to screens. Artificial light exposure, especially the blue parts of it, has become a constant in our day-to-day lives, whether it’s something as simple as blue light exposure from phones, tablets, or laptops, or something more dramatic like LED lights. Blue light’s impact on the skin is a growing concern, even as its impact on sleep and eye health is well known.
Imitation of blue light introduces a variation of high energy visible (HEV) light that could have negative impacts on skin health so the ability to protect skin from blue light is an important consideration in modern skincare. We will then explore how blue light affects the skin, and what we can do to lessen its impact.
The portion of the visible spectrum that is blue has wavelengths between 400 and 490 nanometers and is called blue light. It’s naturally occurring in sunlight and artificially in digital screens, electronic devices and fluorescent bulbs. Natural blue light from the sun helps regulate our circadian rhythm and improve alertness, but artificial sources are more problematic since they expose us to constant, but close-range, sources of artificial light.
While we try to protect ourselves from the dangers of UV light with sunscreen, blue light is usually overlooked when discussing how skin is damaged. But the thing is, exposure to blue light from our digital devices and indoor lighting isn't exactly new, but exposure is widespread and cumulative — and dermatologists, and skincare experts, are worried about it.
Earlier research has already proven that blue light penetrates deeply into the skin compared to UV rays and reaches the dermis layer, where collagen and elastin are found. This deep penetration can lead to a cascade of detrimental and harmful side effects such as oxidative stress, inflammation and DNA damage. Here’s how blue light impacts the skin:
Reactive oxygen species (ROS), unsteady molecules that damage skin cells, are produced under blue light exposure. Premature ageing, a dull skin tone, and even skin tone are all caused by this oxidative stress.
Using blue light, deep into the dermis, it speeds up the breakdown of collagen and elastin, the proteins that give skin elasticity and firmness. Over hours, or even days, this contributes to sagging, fine lines and wrinkles.
Studies have shown that blue light exposure may stimulate melanocytes, the pigment-producing cells of the skin. Dark spots, uneven pigmentation and worsening conditions such as melasma are due to over production of pigments.
Overexposure to blue light can weaken the skin’s natural barrier and the skin will become more prone to external assaults such as pollution and bacteria.
For people with sensitive skin (rosacea, eczema) and acne can make blue light inflammation worse.
Since digital devices are everywhere, digital wellness is essential for fighting red light with your skin. Digital wellness is the pursuit of adopting habits that are healthier around technology. Here are some strategies to protect your skin while maintaining a balanced digital lifestyle:
Reducing screen time can significantly reduce the level of exposure to blue light. Place a cap on your screen time, have breaks regularly (20-20-20 — look at something 20 feet away for 20 seconds every 20 minutes), and focus on offline tasks for a change.
All modern devices have the option of built-in blue light filters or “night mode” settings to reduce the amount of HEV light emitted. You may consider the installation of more software or apps that will additionally limit the exposure to blue light.
At home switch to warm LED light and dim lighting in the evenings for a blue light-friendly environment.
Full skin protection against the blue light includes both skincare products and lifestyle changes. Below are some effective strategies to shield your skin from the damaging effects of blue light:
Now many skincare brands are selling products made to protect against blue light. Antioxidants like vitamin C, niacinamide and resveratrol, all help to neutralise free radicals and repair skin damage. Some sunscreens include ingredients to fight both UV and HEV light.
Generally speaking, the thinking is that sunscreen is only meant for outdoor activities — but that is not the case, wearing sunscreen indoors, even without exposure to screens or windows, is important. Choose a broad-spectrum sunscreen with physical blockers (zinc oxide or titanium dioxide) that deflect the blue light.
The reason behind blue light exposure is dehydration, which is why you should well moisturize your skin. To keep your skin not so dry try to use hydrating serums, creams or mists to maintain your skin’s moisture barrier.
Good tools to decrease exposure are anti-blue light screen protectors and glasses. Not only do they protect your eyes, but HEV light also limits the amount of HEV light reaching your face.
Your skin’s protection from blue light goes far beyond topical solutions, and your overall health and wellness matter greatly. Proper hydration, a balanced diet, and good sleep hygiene will help your skin to have its own natural defence. Here’s how to fortify your skin from within:
Combat oxidative stress by including foods like berries, nuts, green leafy vegetables and green tea. These nutrients help neutralize free radicals and heal the skin.
Water keeps your skin hydrated and helps recover from blue light’s drying effect.
Blue light interferes with the production of melatonin, which hurts your sleep cycle. If you don’t sleep well, then skin repair is poor and ageing occurs too quickly. Create a screen-free, sleepy time routine for sleep.
By increasing blood circulation, physical activity gets blood pumping to the skin and delivers essential nutrients and oxygen. It supports collagen production and also helps to fight signs of ageing.
Blues light has become something of a buzzword, but there are also misconceptions about how it affects the skin. One of the common myths is that blue light exposure under the screens is not as bad as sunlight. The sun indeed emits more blue light, but screen exposure just doesn’t stack up — the exposure is cumulative and very close.
Additionally, people also believe that the use of skincare products alone would give you complete protection. In reality, optimal skin protection combines lifestyle changes and skin care.
With a knowledge of the effects of blue light on skin growth, beauty and tech arms are getting creative with new, innovative solutions. And as wearable tech continues to evolve to minimise blue light exposure, and cutting-edge skincare products find ways to mitigate HEV light damage, this field looks bright.
Research into the long-term effects of blue light will also aid in understanding how to provide protection for our skin health and supply our consumers with the information to make an informed choice.
You know that blue light is changing the skin, in today’s digital world. You can’t eliminate exposure but you can do a lot regarding reducing your exposure daily and practicing mindful best practices in the professional world. There are things you can do to protect your skin from blue light damage though, from antioxidant-rich skincare products to practicing your digital wellness. Today you can help yourself in protecting and maintaining your skin's health and radiance for years to come.
