Blue-light protection determination in vitro
About 50% of the sun´s radiation arriving on earth is visible light. For a long time, the effects on human health have not been fully investigated. But recently, the influence of visible light (VIS) has gained more attention, especially regarding skin physiology. Studies showed various effects, many of them harmful, comparable to UV-radiation.
With the help of a in house developed easy-to-perform in vitro method we are able to determine the direct VIS-protection by measuring the transmittance of sunscreen and cosmetic samples for the wavelength bands of 400-495 nm and 495-630 nm.
