Blue Light – this is the shortest wavelength range of visible radiation, which has the highest energy. It has a wavelength between 380 and 500 nm, making it one of the shortest radiations, but with the highest wave energy.
Normally, it regulates many processes in our body, however, when exposed to excess, it can damage the skin in the same way as ultraviolet rays.
And since blue light comes from almost all gadgets, every modern person is at risk. Specially for the readers of estet-portal.com , a dermatovenereologist, trichologist Ksenia Kisimes spoke about the dangers of blue light.
Why blue light can be dangerous
Blue light – it is a circadian rhythm regulator that is responsible for our natural sleep-wake cycle, speeding up reaction times, elevating mood and enhancing feelings of well-being.
But it also has its downsides.
Blue light waves are the most scattered. Much of the annoying glare of solar radiation is due to blue light.
Research has shown that blue light is 15 times more damaging to the retina than the rest of the visible spectrum.
The intensity of blue light affects image contrast and visual acuity, and causes visual fatigue symptoms.

How gadgets impair skin health
Because the blue light – it is part of the solar radiation spectrum, it is impossible to avoid exposure to it. But the most unsafe is not natural, but artificial blue light emitted by energy-saving compact fluorescent lamps and liquid crystal screens of electronic devices: phones, computers, tablets, TVs and many other gadgets. And there are too many of them in our life today.
Flickering slightly, they create glare that can reduce visual contrast and affect sharpness and clarity, causing:
• eye fatigue;
• headaches;
• physical and mental fatigue with prolonged exposure.
Prolonged exposure to concentrated blue light energy can damage the skin, causing oxidative stress in living skin, which can contribute to photoaging (discoloration, inflammation and weakening of the skin's protective functions). The Benne Bellum Skin Tech Pharma Group, represented by "Academy of Scientific Beauty", is equipped with a special blue light filter that allows you to protect the skin not only during the day, but also at night.

Which is more dangerous: blue light or sunlight
The ability of blue light to penetrate deeper into the skin than UVA and UVB ultraviolet rays, all the way to the dermis where collagen and elastin reside, resulting in skin laxity and sagging.
Skin exposure to the blue light we receive from the sun causes more pigmentation, redness, and puffiness than when the same person's skin was exposed to comparable levels of UVA rays (Journal of Research Dermatology in 2010).
Spending four to eight hour workdays in front of a computer exposes the same amount of energy as 20 minutes in the sun at noon.
Studies have noted that blue light, unlike UV rays, does not activate DNA mutations, therefore, radiation from lamps, tablets, computers or phones cannot provoke skin cancer.

How to protect your skin from blue light
With regard to the skin, today it is necessary to use cosmetic products with protection not only from UVA / UVB, but also from HEV radiation (blue light) in everyday life.
HIGH-ENERGY VISIBLE LIGHT FILTER – radiation-resistant ingredient against photoaging and chronoaging. HEV protection on packaging will become a must for cosmetic products, like today UVA/UVB protection, anti-pollution. Such a filter is already available in the products of the Benne Bellum Skin Tech Pharma Group (Spain) line, presented by «Academy of Scientific Beauty», for the treatment and prevention of all types of hyperpigmentation.
