Blue light pollution: the effects on the skin and how to defend yourself


A hyper-connected life exposes us to a new and subtle form of pollution: blue light. The risks? Especially cutaneous, from which it is necessary to defend themselves with specific broad spectrum filters

It seems that protecting yourself from the sun and smog is no longer enough to prevent skin aging: a new enemy threatens the beauty of the skin. This is the blue light, emitted both by the sun and by you digital devices (smartphones, tablets, PCs, televisions and LED lights).
Recent studies have found that blue light is capable of causing skin damage relevant, such as spots, wrinkles and greyish complexion. Especially in the face of one hyper-connected lifestyle, and taking into account that, on average, each person spends 6 hours a day in front of the 4 screens of the devices they own.
Some American dermatologists have also calculated that spending four 8-hour working days in front of a computer exposes us to the same amount of energy as 20 minutes in the midday sun. So much so that we talk about “blue light pollution“A danger as subtle as it is imperceptible, since we do not notice it.

What is blue light?

Known in physics as visible high-energy visible light (or HEV), blue light is a wavelength of light that comes from both natural sunlight than from the artificial one of screens digital. When emitted by the sun, blue light has positive effects on mood, memory and cognitive function in general.

Another concern is the impact of blue light onskin hyperpigmentation, like (if not more) UV rays, even if we have to wait for long-term studies to establish their reliability.

The bad habit of falling asleep with your smartphone

The blue light emitted during the day is not enough to undermine us, the danger also creeps in night, when we fall asleep with eyes glued to a digital screen.

The latter continue to work as if it were day, compromising their natural overnight repair process. This can lead to visible signs ofaging, and constant dark circles.
