Russian scientists from Nizhniy Novgorod developed an ultrasonic device, which fights acne. Ultrasound causes no allergy, unlike many pharmaceuticals, and shows strong antibacterial effect.
      
      Developers claim that their creation needs only seven days to eliminate signs of acne from human skin. Wonder device will be tested in the USA, where acne tortures about 50 million people.
      
      Nizhniy Novgorod Institute of Applied Physics is famous for its developments of ultrasonic hardware – physicists create these devices for over 20 years.
