The function of galvanic current utilizes direct electric current, which does not change its direction or intensity. Upon contact with the skin, it creates a stable electric field between two electrodes, a positive and a negative one. This allows for two main procedures. The first is "iontophoresis," where the current helps to introduce active substances from cosmetic products, such as serums or gels, deeper into the skin. The device uses the same polarity for the electrode and the active substance, thereby repelling it and "pressing" it into the tissue. The second procedure is "desincrustation," which is a deep pore cleansing. During this, a special solution is applied to the skin, and the action of the current causes a chemical reaction that softens and liquefies sebum, making its removal easier.
