Amorepacific, the South Korean beauty conglomerate, had made advances in research determining the impact of blue light on the skin.
A study published by the maker of Sulwhasoo and Innisfree in the Journal of Cosmetic Dermatology has reported that blue light with a wavelength of 45 nanometres (nm) can cause pigmentation on human skin.
Blue light is generally emitted from digital devices, such as phones and televisions, and can range from 380−500nm.
The company's Anti-Pollution Research Center has developed a device that can reportedly detect potentially harmful blue light wavelengths.
Based on the findings, Amorepacific produced a 'blue light blocker' device that uses a filter containing titanium dioxide to prevent skin pigmentation.
The brand owner stated that it plans to conduct further research on environmental impacts on the skin and "continue developing products to protect the skin health of customers around the world".
Amorepacific described the development as the "world's first clinical evaluation method for blocking blue light from reaching the skin".
The interest in the potential impact of blue light on the skin has gained momentum in recent years.
In September, scientists at Unilever issued a warning to employees working from home about the impact of screen time on their skin.
New research from the beauty giant, conducted in August, revealed that screen time from home working could be negatively impacting skin health, with five days in front of a laptop equating to 25 minutes in midday summer sun without any SPF.
Meanwhile, recent launches from Su:m37°, Goop and Chantecaille all claim to protect against blue light.
