In recent years, various researchers have warned about the damage of blue light on the eyes, or the impact on sleep. This time, an American dermatologist believes that this light emanating from screens can affect the epidermis. It would indeed be a question of an acceleration of the aging of the skin.
In 2018, Spanish researchers determined that blue light is a risk factor for age-related macular degeneration (AMD). It is a disease of the retina usually affecting people between the ages of 50 and 60. A few months earlier, a study funded by the European Union had made it possible to understand why blue light from screens disturbs sleep. The fact is that in the case of use at night, it prevents the secretion of melatonin , an essential hormone for sleep.
But, obviously, we haven't finished hearing about blue light! Michele Farber, skin specialist for the Schweiger Dermatology Group, was interviewed in an article published by the Huffington Post US April 30, 2020 Prolonged exposure can cause irreversible damage at skin level. It can be sagging, fine lines or even the appearance of darker spots. In short, it is about an acceleration of skin aging.
“Watching our televisions and phones the night can also upset our sleep cycle. We now know that a lack of sleep causes hormonal disturbances that can lead to skin problems and accelerate aging » said Michele Farber.
On the other hand, this news should not cause undue alarm. Indeed, the effects of the sun are much more harmful because it can cause skin cancer. Moreover, too few studies and statistics are available. In other words, it is very difficult to assess the real risks relating to exposure to blue light.
In the meantime, consumers should try to protect themselves. For example, many screens have a blue light filter option , synonymous with protection. In addition, there are glasses equipped with blue light filter lenses. However, both can be used in addition.
Michele Farber also mentioned the possibility of using sunscreen . On the other hand, it is incumbent on you to have a product whose formula protects against blue light by reflecting light rays, that is to say a cream composed of titanium dioxide and zinc oxide.
