There is no doubt that the effects of the Corona pandemic are multiple, some of them have a long-term impact, especially since working from home has increased the periods of stay in front of computer screens and smartphones, whether for work and virtual meetings, shopping for home needs, or to follow the news of the pandemic itself and communicate with friends and family virtually.
Experts recommend using skin care products that contain antioxidants, as well as niacinamide and zinc oxide. Experts recommend the need to be aware of the danger of blue light emitted from screens and work to limit the time of exposure to it, as it harms the skin as well as public health.
And according to what was published by the British "Daily Mail", the results of a new scientific study indicate that staring at a computer screen or mobile phone throughout the week can be harmful to facial skin as much as the negative effects that result from exposure to direct sunlight without protection by a protective cream.
Premature aging of the skin
Scientists working for a company specializing in consumer products have studied the effects of the "blue light" emitted from electronic device screens on the skin and found that it can cause premature aging.The results of the study revealed that 60% of people now spend more than six hours a day in front of a digital device equipped with a screen that emits blue light.
And the results of the study showed that exposure to blue light for five days for at least six hours a day can have the same effect on the skin as spending 25 minutes in the sun without cream.
Skin and the biological clock
The science team says it is already known that exposure to blue light can cause hyperpigmentation and premature aging, but an accurate measurement of the appropriate daily exposure duration is still needed.The results of a survey as part of the study showed that two out of three people are not aware of the effect of blue light on their skin and their biological clocks.
The most dangerous of ultraviolet
The research team warned that the blue light of a computer screen, smartphone or tablet can penetrate the skin much deeper than UV rays from the sun, and that it passes through the epidermis and dermis to the subcutaneous layer.More negative effects
The results of the study indicated that blue light could cause immediate and persistent pigmentation, and it could remain present for more than three months. Blue light can inhibit melatonin production, increase stress hormone levels, and stimulate nerves, which in turn disrupt sleep patterns and the circadian rhythm.Changes in skin cells
Dr. Emma Wedgworth, a consultant dermatologist at the British National Health Service, explains that blue light may damage the skin by generating "free radicals", explaining that "these free radicals are very active molecules that stick to the skin and cause major cellular changes." They affect the way DNA is repaired. "Dr Wedgworth notes that any potential harm is likely related to "the amount of time we spend on our phones and the fact that we keep them in direct contact with our skin for extended periods of time."
The results of the study revealed that 30 hours of exposure to blue light from smart phone or laptop screens can increase the level of inflammation in skin cells by 40%.
