Nanoparticulate materials are already common in sunscreens.

  • they provide better skin coverage and more effective protection from the sun’s ultraviolet rays.
  • nanoparticles may enter cells and cause damage.
  • they may also be harmful to the environment.
  • they could be more reactive or toxic than bulk material.
  • these risks are difficult to determine because nanoparticles have not been in use for very long.
