Blue light: Smartphones & Co. are so bad for our skin

Blue light

A suitable sun protection factor is, of course, our daily companion – after all, sun rays are one of the greatest skin aging factors. But what about the light radiation from our digital devices? How harmful the blue light from computers, smartphones and the like really is and how we can protect ourselves from premature wrinkling.

Digital aging: wrinkles through smartphones, TVs and PCs
The use of smartphones, laptops and tablets are firmly anchored in our everyday lives. Especially in the current crisis, we tend to spend a little more time in front of our digital devices. But the so-called bluelight, which the devices emit, supposedly causes wrinkles and a pale complexion. How harmful is blue light really for our skin?

The phenomenon of digital aging: that’s behind it
We are all familiar with the premature formation of wrinkles caused by sun rays. In the meantime, almost every day care product contains a sun protection factor , so that we are protected from the aggressive radiation around the clock. What has received less attention in our care routine so far is the blue light from digital devices.

The term “digital aging” describes the development of premature skin aging through the use of smartphones, tablets and Co. The screens emit what is known as blue light, which does our skin no favors!

Blue light: what is it actually?
In contrast to solar radiation, the light that radiates from our screens is not natural light. It has a wavelength between 380 and 500 nanometers and a very high energy charge. Technically correct, blue light is called HEV radiation (high-energy visible).

Digital devices: that’s how harmful blue light is to the skin
The artificial, blue light penetrates deeper into our skin than natural UV radiation does. The result: the formation of free radicals is favored. Free radicals are known as beauty killers in the beauty industry. Anti-aging products therefore often have active ingredients that help capture free radicals. If the free radicals run unhindered in our body, they destroy the DNA in our skin and thus promote the development of pale complexions, wrinkles, pigment spots and other signs of aging.
In addition, the connective tissue is affected. Fibers such as elastin and collagen, which ensure the resilience and elasticity of the skin, are destroyed by HEV radiation.
Furthermore, blue light can unbalance our skin barrier, which makes it easier for other harmful substances to penetrate our skin.

Premature wrinkling: this is how we can protect our skin

As digital devices take up more and more space in our everyday lives, the topic of blue light in skin care is also becoming more important. More and more cosmetic companies are bringing out products with a sun protection factor that not only protects us from UV radiation, but also from HEV radiation.

But we can counteract premature skin aging not only from the outside, but also from the inside. An important factor here is diet : foods with naturally occurring antioxidants are perfect because they bind free radicals and thus protect our skin from wrinkles. Great skin foods include berries (the darker the better), nuts, tomatoes, broccoli, cabbage, avocado and citrus fruits.

Also helpful: take a digital break every now and then . Whether it’s a day without a smartphone, an evening without a TV or a room in the apartment where digital devices are taboo – every restriction relieves your skin. Try what is possible for you. For example, grab a book before bed instead of lounging in front of the TV.
