New York: In a major relief from the risky botox process for skin revitalisation, a non-invasive technique that harnesses pulsed electric fields to generate growth of new skin tissue has been devised, says researchers.
The novel non-invasive tissue stimulation technique, developed by a team of Tel Aviv University and Harvard Medical School researchers, utilises microsecond-pulsed, high-voltage, non-thermal electric fields to produce scar-free skin rejuvenation.
"Our new application may jumpstart the secretion of new collagen and capillaries in problematic skin areas," said lead researcher Alexander Golberg from TAU.
Botox, which smoothes lines and wrinkles to rejuvenate the ageing face has been the number one non-surgical procedure in the US since 2000. But injections of this toxic bacterium are only a temporary solution and carry many risks.
Current therapies to rejuvenate skin use various physical and chemical methods to affect cells and the extracellular matrix, but they induce unsightly scarring.
Pulsed electric fields, however, affect only the cell membrane itself, 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.
"The technique may revolutionise the treatment of degenerative skin diseases," the researchers said.
"In the modern era of ageing populations and climate change, degenerative skin diseases affect one in three adults over the age of 60, this has the potential to be an healthcare game changer," Golberg said.
The researchers are currently developing a low-cost device for use in clinical trials in order to test the safety and efficacy of the technology in humans.
The findings were published in the journal Scientific Reports.
