chosen.content: Nanoparticles – used in cosmetics such as toothpaste, lipstick, or deodorant – are tiny particles over a thousand times thinner than the diameter of a human hair. For example, the pigments titanium oxide and zinc oxide are used in sunscreens and stay like a film on the skin to reflect sunlight.
  
  That all sounds positive at first, but the nanoparticles in cosmetics are controversial. Their effect on humans and the environment has not yet been adequately researched, and many meaningful studies have not been conducted. How tiny nanoparticles used in cosmetic products affect our health is completely unclear.
  
  Studies by the Federal Environment Agency on nanoparticles suggest a possible carcinogenic effect of some nanomaterials. These may include carbon nanotubes or titanium dioxide, which should be taken seriously.
  
  Many cosmetic products also contain nanoparticles. Silver nanoparticles in deodorants have antibacterial properties. Other types of particles in creams and lotions help the skincare products get absorbed into the skin more easily. Toothpaste with nanoparticles fills the finest cracks in the teeth. Kohl pencils and mascaras have a longer shelf life, thanks to nanoparticles.
  
  Nanoparticles don't get through the skin if it is healthy. However, they can get into the blood via the respiratory tract. At the beginning of the year, scientists from the Center for Medical Biotechnology shared initial findings on how nanoparticles could influence our stomach and intestinal flora. According to this, nanoparticles can bind to harmful and beneficial bacteria, including probiotic germs.
  
  The immune system can recognize pathogenic bacteria more poorly when covered with nanoparticles. It promotes intestinal inflammation. Certain nanoparticles weaken the infectivity of the Helicobacter pylori germ involved in the development of gastric cancer.
