It's not news to hear more harmful effects of your phone. But new studies have found the light projected for your phone damages your skin. So if a phone detox has crossed your mind for a productive purpose, it could be much more beneficial to take some time away from it, for the benefit of your skin. Research from scientists and dermatologists have determined that High-energy visible light, or what you would know as 'blue light' from your phone, could have more damaging properties than sunburn can.
This light from our phones, tablets, computers, laptops and TVs has also been shown to generate more reactive oxygen species than UVB and UVA combined. Sometimes referred to as free radicals, these ROS attack healthy cells and lessen these cells’ ability to repair themselves
Asia Pacific global educator for Murad skincare, David G Whyte has started to observe the effects of HEV. There are no apparent effects as of yet as its too early to tell, however, Visible blue light has one of the shortest, highest-energy wavelengths, able to penetrate the skin more deeply than UVB and UVA rays. Which would suggest that there is potential for it to be more damaging than the sun, in the future.
Too much blue light can speed up the oxidation process which means it can increase pigmentation and inflammation. Whyte explains that this can damage a layer of the skin and make your skin more prone to premature ageing.
While blue light has these chemical properties, it is still too early to be confident with these damaging effects, as they are still being studying. However, Unilever has performed a study which suggests spending 8 hours of your workday in front of the computer is the equivalent of spending 20 minutes in the hot midday sun. This is before you've even got home to spend more time on your phone!
“Blue light emitted from a TV screen across the room can still have an impact.”
Blue light has other adverse effects, and it has been linked to eye strain as well as sleep disruption. Therefore Whyte strongly suggests using a blue light filter on your phone, or just switching your phone to night mode, so it emits less concentrated blue light.
