Artificial blue light has negligible effect on skin, finds Beiersdorf study

New research from German multinational personal care company, Beiersdorf, clears up misconceptions about the effect that blue light has on skin.


Beiersdorf’s new research maintains that concerns about the artificial blue light of laptops, tablets and smartphones are unfounded


As one of the pioneers in sun protection, Beiersdorf has spent many decades researching the effect of UV rays on the skin. The company started to research blue light due to the increasing number of hours people spend in front of laptops, smartphones and TV screens increases, particularly during the coronavirus pandemic.


A Beiersdorf statement reads: “We are already well aware of the effects of the blue light from the sun, which is why there is suspicion that the artificial screen variant might also damage the skin – often on the basis of insufficient evidence. Beiersdorf research provides sound findings that offer some insights into the effects of natural blue light – high-energy visible (HEV) light – and artificial blue light on the skin.


“Our research team was headed by Dr Ludger Kolbe, chief scientist of Photobiology, who has refuted the sometimes critical voices circulating on the subject of artificial blue light. Dr Kolbe says: ‘Public discourse has been characterised by a lack of knowledge and of scientific studies. But through our research activities, we’ve managed to prove that the amount of artificial blue light emitted during conventional use of electronic devices is nowhere near enough to trigger harmful skin effects.’ If you were to spend an entire week in front of a monitor, uninterrupted, at a distance of 30cm from the screen, this would be the same as just one minute outside on a sunny summer day in Hamburg at midday.


“Dr Kolbe points out that compared to the emissions of the sun’s natural blue light, those of artificial blue light are virtually undetectable. Even if you were to sit close up to the screen, this would have little impact on the results. While HEV intensity increases by a factor of 17, a 10-hour phone call on a smartphone, for example, would be the same as a minute in the sunlight on a sunny day in Hamburg.”
