How to protect your skin from too much blue light

Following research into the effect that the blue light emitted from screens can cause damage in a similar way to the sun’s rays, we look into the products that are specially designed to protect our skin…

Blue light from your laptop, phone and tablet has been linked to premature skin ageing and irregular pigmentation. But what exactly is blue light? 

According to Stefanie Williams, dermatologist and medical director at Eudelo, “Blue light (AKA high energy visible light, HEVL) is part of the visible light spectrum. It’s the electromagnetic radiation that sits between ultraviolet and infrared radiation, and it consists of different colours with blue light being the closest in wavelength to UV light.”

Sounds complicated, but the most important thing to note is that blue light is emitted from electronic devices like televisions, computer screens, laptops and tablets… the list goes on. Even some fluorescent bulbs and LED lights can emit it. “And, of course, the sun emits blue light, too,” adds Williams.

While it has long been known that blue light can interfere with our circadian rhythm, Williams says that there is increasing data on the potential long-term harms of visible light, particularly blue light.

In fact, just last month, new research discovered molecular and cellular changes in human skin cells exposed to artificial visible light, similar to the light emitted by electronic devices. “The authors concluded that that may impede normal cellular functions and contribute to premature skin ageing,” Williams explains.

So, with that in mind, brands are starting to create products to help protect skin from potential harm. Here are three of Stylist’s best rated…
