Unilever scientists unveil how blue light can cause skin damage akin to the midday sun

THE WHAT? Unilever has unveiled a study that showcases how blue light from tech devices can damage the skin to a similar extent as standing in the midday sun without protection for 25 minutes. 

THE DETAILS According to the study, 64 percent of people are unaware of the effect that blue light can have, with the company stating, “The blue light emitted from screens not only affects the skin but can also disturb our biological clocks. Blue light can penetrate the skin far deeper that UV light, passing through the epidermis and dermis to the subcutis layer.”

The study suggests that ongoing exposure to blue light can induce both immediate and persistent pigmentation, with the rays being able to inhibit melatonin generation, increase stress hormone levels, and excite nerves. 

Samantha Tucker-Samaras, Global Vice President Science & technology, Beauty & Personal Care continued: “Long-term exposure to blue light has the potential to have a significant negative impact on people’s wellbeing, and we’re concerned people are simply unaware of the risks.”

Protection methods include choosing products that include ingredients that minimize or neutralise blue light, such as Zinc Oxide, Vitamin C and Vitamin B6.

THE WHY? As home working becomes the norm following the outbreak of COVID-19, the study aims to raise awareness about the need to protect the skin when working on electronic devices, as well as when in sunlight. 

Tucker-Samaras, continued: “It is highly likely that exposure to blue light has increased this year, as many previously office-based workers have increased their time in front of a screen, as face-to-face meetings have moved to virtual. People should be looking for skincare products loaded with antioxidants, as well as niacinamide and zinc oxide. Limiting screen time also helps, not only for our overall skin health, but our general wellbeing too.”

  1. It may help to generate vitamin D, just as normal sunlight does.

    Btw. Microsoft added a blue light limiting feature to Windows 10 in the Creators Update released in April 2017. Called night light, this feature shifts the Windows 10 display to show warmer colors that reduce the amount of emitted blue light. Turning the feature on is a simple process.
