Blue Light Buzz
Let’s start with some facts…
Millennials check their phones upwards of 150 times a day.
In a professional capacity, we spend 10+ hours in front of computer screens every day.
The rate of skin ageing has dramatically increased in recent years.
Since the digital age was established in 2012 there has been a truly dedicated level of disregard to any of its potentially harmful effects to our mental and physical health. Exposing ourselves to the residual light from screens for such a staggering portion of our days, suddenly (as a kid of the 80’s there is a distinct ‘before’ and ‘after’ mobiles and tablets in my memory), leaves a nagging thought about what visible light could actually be doing (if anything) to our skin and the overall ageing process.
So what exactly is blue light and why is it harmful?
We all know that the sun, as the world's primary light source, emits both visible and invisible light rays and that both have the ability to age our skin. It therefore goes without saying that other light sources, namely digital screens, also give off light rays - in this case blue light which has relatively short wave lengths and packs a heap of energy. In small doses, exposure to the suns rays is hugely beneficial, helping the body manufacture vitamin D. But, when we sit in front of a screen all day long and tap into our social media sporadically throughout the evening, does that level of exposure to blue light have any adverse effects on our skin?
Despite the recent media buzz on its detrimental effects, research on how visible light affects the skin is ongoing. What was touched on at the recent World Congress of Dermatology in Milan however was findings that the level of blue light emitted from tablet, phone and laptop screens is actually very low. The intensity of the emissions is in fact so low that most people would need to sit with multiple screens in their face for a consecutive 150+ hours to achieve the minimal pigmentary dose.
Conclusion: we should be more concerned about blue light from the sun on our skin than from our devices. The sun remains, by far, the element of daily concern for our skin's integrity and the front runner in contributing to photo-ageing including wrinkles, worsening skin laxity and hyperpigmentation.
To protect your skin from blue light emitted from the sun’s radiation use physical blockers such as iron oxide and zinc oxide. Research shows that blocking visible light with sunscreen containing iron oxide prevents the occurrence of Melasma. The use of antioxidants also helps to mitigate the damage caused by visible light, infrared and ultra-violet light.
