Dermatologist discovers face-saving nano ingredient

Acne is the scourge of modern youth. It is caused by a number of factors such as excess production of skin oil, the plugging of pores and by bacterial infection. Various over-the-counter treatments are available but these often have side effects such as causing skin to scale and drying out.

Robert Modlin, a dermatologist at the University of California, Los Angeles, US, and colleagues say they have come up with an exciting new treatment based on nanoparticles of chitosan, a polysaccaride from the shells of crustaceans like crabs and shrimps.

While investigating chitosan as a carrier for antibiotics the team made the surprising discovery that the material can kill various bacteria by itself. They say that biodegradable nanoparticles could be used to treat acne and to carry other compounds such as antioxidants and collagen. How long before teenagers are smearing their faces with ground shrimp shell?
