Most of us understand the damage that UVA and UVB rays from the sun can cause, but fewer realise that blue light (including from our digital devices and screens) can also affect our skin health.
We're exposed to blue light every day, mainly from the sun, with smaller amounts coming digitally and via LED lighting, explains Consultant Dermatologist, Dr Derrick Phillips. But people are less aware of the effects of blue light because the evidence is relatively new. "For decades, sun safety messaging has quite rightly focused on UV radiation, as its link to skin cancer and ageing has been well established. By comparison, we’re only now beginning to understand how blue light affects the skin, particularly in relation to pigmentation and premature ageing, so public awareness has yet to catch up with the science."
