Electric fields induce nanoscale deficits to rejuvenate skin

Harvard and Tel Aviv University researchers have developed a non-invasive tissue stimulation technique, utilizing microsecond-pulsed, high-voltage, non-thermal electric fields, to produce scarless skin rejuvenation.  Already effective in tumor removal and wound disinfection, the technique may revolutionize the treatment of degenerative skin diseases.

Current skin therapies use  physical and chemical methods to affect cells and the extracellular matrix, but induce scarring. Pulsed electric fields only affect the cell membrane, preserving the extracellular matrix architecture and releasing multiple growth factors to spark new cell and tissue growth. By inducing nanoscale defects on the cell membranes, electric fields cause the death of a small number of cells in affected areas. The released growth factors increase the metabolism of the remaining cells, generating new tissue.
