We spend most of the day in front of the phone, TV and computer

Recently, a growing question has arisen as to whether blue light from the screen can damage your skin. With endless browsing on Instagram before we get up in the morning, an eight-hour workday at the computer, and a few episodes on Netflix at night, it’s safe for many of us to spend most of the day in front of a screen. to bring.

While it’s clear that we’re spending more and more time in front of the screen, we need to know that it’s not always that bad: it’s a social connection, and industries are dependent on business technology, and this story would not exist without the screen. But the reality is that all that time spent behind the scenes negatively affects our lives in obvious (your sleep, memory and even metabolism) and less obvious ways (your skin).

Sure, experts will tell you to reduce the time spent in front of the screen, but depending on the job or lifestyle, it may not be possible, Shape reports.

“I think we need to embrace technology and all the wonderful ways it has improved our lives. Just make sure you protect your skin while doing so, ”says Janice Trizino, vice president of product development at Goodhabit, a new skin care brand that combats the effects of blue light.

What is blue light?

“The human eye is able to see light as a specific color when it hits a certain wavelength. Blue light is a type of light that emits high-energy visible (HEV) light that lands in the blue part of the visible light spectrum. In context, ultraviolet light (UVA / UVB) is on the spectrum of invisible light and can penetrate the first and second layers of the skin. “Blue light can reach up to the third layer,” says Trizino.

“There are two main sources of blue light: the sun and screens. The sun actually contains more blue light than UVA and UVB combined, ”says Loreta Ciraldo, a Miami dermatologist.

“All digital screens emit blue light (your smartphone, TV, computer, tablet and smartwatch), and the damage is based on the proximity of the face to the device and the size of the device,” says Trizino. There is controversy about the intensity and duration of exposure to light, and it is unclear whether most of your exposure to blue light comes from the sun, because it is a stronger source, or from the screen due to their proximity and time of use.

New research shows that long-term exposure to high levels of blue light can be associated with some less ideal skin condition, similar to exposure to UV light. It is believed that blue light, such as UV, can create free radicals, which are believed to be the cause of all this damage. Free radicals are small cosmetic particles that damage the skin, such as skin discoloration and wrinkles.

One study even showed that the production of melanin in the skin doubled and lasted longer when exposed to blue light compared to UVA. Elevated melanin levels can lead to pigmentation problems such as melasma, age spots and dark spots.

One good news is that there is no data suggesting a link between blue light and skin cancer.

How can you prevent skin damage with blue light?

“Consider purchasing a blue light filter for computers and tablets, or reduce the blue light setting on your phone. You can also buy blue light glasses that will help you prevent eye strain and harm eye health, but will also prevent the formation of eye wrinkles and hyperpigmentation, ”advises Ciraldo.
