Also known as HEV (High Energy Visible Light), blue light falls right in the middle of the light spectrum. It sits between UV rays (which come from the sun), and infrared rays (which come from heat). You’re exposed to it just by stepping outdoors, but it’s also lurking in the screens of the devices we’re using daily: phones, laptops, even our TV (darn you Love Island). Simply put – it’s the type of light that, between our 9-5 office lifestyle, Instagram browsing and Netflix binges, is nigh impossible to avoid.
From cell damage to dark spots: is your phone wrecking your skin?
The rules of ‘anti-ageing’ are never ending: avoid sunbeds, keep your skin moisturised, always use SPF (yes, even in England). Though we’re all for embracing those laughter lines – signs of a good time, if you ask me – there’s bad news afoot for our skin: recent studies suggest that the blue light emitted from our phone and laptop screens could be causing premature ageing. Here’s the truth, and exactly what you can do about it.
