Some of our customers have asked us: Does screen time damage the skin?
It’s not something we want to think about. After all, most of us can’t just stop using our phones, tablets, and computers.
Fortunately, that is not necessary. However, we need to be aware of how the light emitted from our screens can affect our skin, and what we can do to protect it.
Does screen time damage the skin? It’s all about blue light
Blue light is a part of the visible spectrum of light – the part we can see – that has the shortest wavelength and the highest energy. Although the sun is the largest source of blue light in our lives, artificial sources include fluorescent lights, LED televisions, computer monitors, smartphones and tablet screens.
There are some benefits to blue light. It increases alertness, helps memory and brain function and improves mood. It also helps us regulate our natural circadian rhythm, so we feel awake in the morning and sleepy at night.
Although some exposure to blue light is healthy, it affects us all today too many exposure. We stare at our phones, computer screens and tablets for hours every day, and often at night. Humans have never been in this situation before, with so much blue light shining on our eyes and skin.
Could this be bad for us?
Does screen time damage the skin? The evidence so far
You’ve probably heard that blue light emitted by our screens can affect our eyes. Over time we may experience dry, itchy eyes; tired eyes; and general eye strain. Some studies have even found that exposure to blue light can damage the cornea, lens and retina over time, resulting in changes in vision as we age.
Scientists have now also begun to study the effects of this type of light on the skin. In a recent one 2023 studyFor example, researchers have reviewed the literature available to date on this topic. They found numerous studies showing that exposure to blue light “accelerates the aging process and causes hyperpigmentation of the skin.”
These negative consequences, the researchers warned, “may ultimately lead to more overall skin damage, which can accelerate the aging process.” The recommended skin protection against blue light.
The problem is that blue light can inspire the formation of free radicals in the skin. These are reactive, unstable molecules that can damage skin cells, leading to the breakdown of collagen and elastin.
In a Study from 2019researchers found an increase in free radical production, DNA damage and inflammatory markers in the skin after exposure to blue light.
We can compare the effects with exposure to the sun. It’s not something you’ll notice right away. But the more you expose your skin to blue light over time, the more damage can accumulate.
Does screen time damage the skin? Hyperpigmentation
Some studies have focused specifically on how blue light leads to dark spots, melasma, and other forms of hyperpigmentation.
In 2010For example, researchers found that exposing the skin to blue light caused more pigment, redness and swelling than exposing it to comparable levels of UVA rays. (The sun emits both blue light and UV rays, but blue light penetrates deeper than UV rays.) Although both types of exposure led to hyperpigmentation, the exposure caused by blue light was darker and longer lasting.
“Dermatologists have good evidence to show that visible light causes certain skin conditions, such as melasma, where the skin is stimulated to produce more pigment,” shared Shari Marchbein, a board-certified dermatologist. To tempt magazine. She added that the more time we spend on our devices, the worse our skin “could” get, although we don’t know for sure yet.
Some dermatologists say that anecdotally they see more melasma on the side of the face where people hold their phones. This is different from normal, as melasma typically forms on the central cheeks. They also note that dark spots from acne are often worse on the side of the face where people hold the phone.
How screen time can damage the skin
In summary, based on what we have learned so far, we can say that excessive exposure to blue light can mean the following:
- Generate free radicals, which can then damage skin cells and break down collagen and elastin. Effects can include: fine lines and wrinkles, sagging and bags under the eyes.
- Stimulate melanin activity in the skin, leading to uneven and excessive pigmentation. The results can be dark spots, melasma, and more noticeable acne scars.
- Enhance the effects of photoagingThis is aging caused by light waves (similar to the aging after sun exposure). The results include accelerated signs of aging.
- Weaken the outer layer of skinwhich can lead to dehydration and dullness.
- Disrupt the healing and regeneration of the skin, especially if you are exposed to blue light at night. This could accelerate aging over time.
Does screen time damage the skin? What you can do
This is a new area of research, so we still don’t know exactly how our devices affect our skin. It’s safe to say that excessive exposure to blue light is probably not good for the skin and we can benefit from taking some precautions.
Use devices that block blue light
You can now buy screen protectors that block blue light for all your devices: computers, tablets and phones. These help reduce the amount of blue light reaching your skin and can help reduce your exposure.
Ask about glasses that block blue light
The jury is still out on how well blue light blocking glasses work, but if you spend a lot of time in front of your screen, it’s worth asking your ophthalmologist about them. They can help protect the skin around your eyes from harmful blue light.
Use night mode on your devices
If you use your devices in the dark, make sure to enable the ‘night mode’ option as it will help reduce blue light emissions. On most devices, this option uses softer yellow and orange lights instead. Your other option is to reduce your use of these devices at night. For example, read a real book instead of an e-book.
Wear safe sunscreen
Don’t forget that the sun is also a source of blue light and dangerous UV rays. Use a safe sunscreen made from zinc oxide or titanium dioxide to protect your skin.
Eat a healthy diet with plenty of fruits and vegetables
Fruits and vegetables are high in antioxidants, which you need to fight those pesky free radicals. Make sure you get at least five servings a day for your best skin health!
Invest in quality skin care
Quality skin care is essential when it comes to helping your skin defend itself against the effects of blue light, pollution and other daily aggressions. When your skin has the nutrients it needs and is well hydrated, it can better ward off dangerous free radicals.
Consider looking for skin care that is rich in antioxidants, as this can also help suppress the damaging effects of free radicals. Our CV Skinlabs products are packed with powerful antioxidants, including Reishi Mushroom, Turmeric and Vitamin E, to help protect the skin while promoting repair and regeneration.
