Early in the morning, we take our first glance at our smartphone, at work we sit in front of a PC, and in the evening we relax with a series or show. The average screen time has increased from 8 to 10 hours. During this time, our face is particularly exposed to high levels of blue light. This light impacts not only our sleep and eyes but also our skin.
Blue light, also known as HEV (High Energy Visible) light, is not only emitted by natural sunlight but also by digital devices. Blue light is high-energy visible light. Similar to UV radiation, it causes oxidative stress, which leads to premature skin aging and can damage the DNA of skin cells. Blue light penetrates even deeper into the skin layers than UV-A and UV-B rays. This short-wave blue light is the most energy-intensive radiation, accounting for 50 percent of free radicals and 25 percent of cell damage.¹
