  • the large number of commercially available sunscreens should not, however, obscure the fact that these prior art preparations have a number of disadvantages.
  • Cosmetic sunscreens usually contain filter substances which absorb and / or reflect electromagnetic radiation in the UV-A and UV-B wavelength range. More recently, so-called “blue light radiation”, i.e. electromagnetic radiation in the wavelength range from 400 to 500 nm, has moved into the focus of research. It has been found that this blue light penetrates deeper into the fluff than UV-A or UV-B radiation and thus represents a danger for all fluff layers. Blue light generates oxidative stress in both the reactive oxygen species (ROS) and the reactive nitrogen species (RNS) in the low tide. It softens the epidermal barrier and damages the extracellular matrix. Flyper pigmentation and the destruction of proteins and lipids can result. All of these effects can lead to premature aging of the skin and, based on these findings, it can also be assumed that the other ingredients of sunscreens (e.g. lipids, antioxidants) themselves are also damaged if they are exposed to blue light radiation.
