Effects of blue light on human skin!

Zilās gaismas ietekme uz cilvēka ādu!

Since our daily lives are connected to digital devices - smartphones, computers and LED TVs, there is more and more talk about blue light, or HEV (High Energy Visible light) emitted by these devices, the negative effects on the skin.

Although research is still new and we don't fully understand the effects of blue radiation on us, which we may not know until years from now, it is still worth thinking about and being careful. For example, the fact that UV rays cause malignancy was established by researchers many years after they were first discovered, but although there is a lot of research, there are still a lot of unknowns that are gradually revealed every year (1).

Until now, the alarm about the effects of blue radiation on our health was raised by eye specialists, stating that it contributes to cataracts, glaucoma and other eye diseases (2). Therefore, special safety glasses were created for this purpose. However, dermatologists also emphasize that blue radiation is not good not only for vision, but also for the skin.

The source of blue light is also the sun, and we need it in optimal doses to feel young. Blue light helps to overcome certain types of depression, regulates our circadian rhythm and improves cognitive abilities (3). However, if our daily life involves working at the computer, looking at smartphones for a long time, it undeniably has consequences.

You have probably already noticed that after several hours spent at the computer, the skin on the face, especially in the eye area, looks tired. Focusing on the screen, we don't notice how we strain our eyes, often tightening the skin into wrinkles. It is not for nothing that experts advise those who spend a long time at the computer to leave it every 40 minutes and rest for at least 10 minutes. It not only helps the eyes, but also the back and of course the skin of the face. Ideal if you do some eye exercises, move your arms and shoulders. This will not only help tense muscles, but also promote blood circulation and oxygen access to the skin.

But what are dermatologists worried about? Recent studies show that blue light rays have serious effects on the skin. They penetrate very deep - even to the hypodermis. Dermatologists refer to studies that pigment spots develop on problematic skin affected by purulent bumps, which is exposed to blue light radiation for a long time. Due to blue light radiation, free radicals are produced more in the skin, it suffers from oxidative stress, which damages cellular DNA, contributes to skin inflammation, damage to collagen and elastin fibers, as well as the already mentioned pigmentation. (4). In addition, all this accelerates the aging of the skin.

In order to protect the skin from photoaging caused by blue light, UVA/UVB rays, LABRAINS has developed several products, but we would like to highlight our BB cream with a special formula, which is available in two shades - with an olive and a light undertone.

What can we do to protect our skin from blue light radiation?

  • Spend as little time as possible on digital devices,
  • Reduce the brightness of the screen or turn on the blue light filter, use special protective glasses.
  • Use hands-free as often as possiblesystem and do not keep the computer on unnecessarily.
  • Avoid using smart devices before going to bed so as not to affect the quality of sleep, because blue light reduces the level of the sleep hormone melatonin in the body, and as you know, melatonin is considered a beauty hormone.
  • Choose special care and decorative cosmetics that protect the skin from UVA/UVB and blue light rays. 
  • Regular outdoor activities as much as possible.
