Although most blue light is contained in daylight, typical artificial emitters of blue light are lamps and the screens of laptops, tablets and smart phones. The irradiation of skin with blue light increases the reactive oxygen species (ROS) load of the cells, resulting in oxidative stress with subsequent damage.
Rahn has tested a selection of three Rahn-Cosmetic Actives for their blue light protection index and recommends:
- Celligent UV / HEV protection for DNA, cell and stem cell and rapid regeneration of UV-damaged skin.
- Myramaze, a cell membrane safety guard and blue light protection for stressed, fragile skin.
- Proteolea is a cellular recycling manager plus anti-blue light formula for a six-year skin rejuvenation effect in just four weeks, according to the company.
