What type of current produces an electrochemical effect due to its constant direct flow?

The electrochemical effect is produced by galvanic current due to its constant direct flow. Galvanic current is a type of direct current that maintains a consistent direction of electron flow. This steady flow allows for various electrochemical reactions to occur, such as iontophoresis, where active ingredients in skincare products can be pushed into the skin.

In cosmetic and esthetic applications, the ability of galvanic current to create an electrochemical effect is particularly valuable for processes like deep cleaning of the skin and enhancing product penetration. The constant directionality also plays a significant role in how electrical energy is transformed into chemical energy to create desired effects on the skin.

Other forms of current, such as alternating current and pulsed current, do not provide the same consistent flow necessary for electrochemical reactions. Consequently, they are used for different therapeutic effects, such as muscle stimulation or pain relief, rather than the electrochemical benefits directly associated with galvanic currents.
