Conductive gel for iontophoresis | approximately 0.5 mA/cm2. Mesotherapy Serum

 


In the medical practice, it is often desired to make electrical contact to the body. Such contact may be for the purpose of measuring electrical signals or applying electrical impulses during electrotherapy. One of these therapies is the iontophoresis also called ionic transfer, which consists in the penetration of substances in the organism by means of galvanic current. This method enables the ionic migration of the applied substances due to the constant and unidirectional emission of the electric flow. To achieve this, a small direct current (approximately 0.5 mA/cm2) passes through an electrode holding the drug in contact with the skin and a ground-electrode placed anywhere on the body completes the electric circuit. The transport of charged molecules is driven primarily by electric repulsion of the motriz electrode. Neutral polar molecules may also be released by a flow of connective water induced by a current (eletroosmosis). For this therapy to be successful, the skin, in virtue of its dielectric nature, needs to be adapted to provide a reliable, low resistance electrical contact. This can be achieved by the use of an electrically conductive gel. The contact with the skin of those gels is particularly ensured by eliminating the voids and areas of poor or intermittent contact, which may result in the generation of spurious electrical signals. Institute BCN Conductor Gel consist of an aqueous solution of a crosslinked agent containing ionized salts (even at saturated concentrations) and polarizing substances. The presence of these latter may be used to distinguish this gel from those for ultrasonic applications. Furthermore, Institute BCN Conductor Gel can also be combined with drug solutions to be applied providing a homogeneous medium for their distribution and release.
