The process, which utilises the enhanced permeability of cellular membranes upon contacting electric fields is called electroporation. The technology is frequently called mesotherapy without a needle. The reference to mesotherapy exists because the special electric waves emitted by the appliance – similarly to the channels opened on the horn layer (barrier) of the skin by the thin and fine mesotherapy needle - create openings between the skin surface and the deeper layers, which are real, although invisible to the bare eye. Through these openings any agent (regardless of molecular weight) applied on the skin can work with extraordinary efficiency and is absorbed into the skin much more intensively when compared with other absorption-enhancing traditional agent-introduction methods.
