What is the term for direct current causing a chemical reaction?

The term for direct current causing a chemical reaction is "Galvanic." This type of current is characterized by the flow of electricity in a single direction, which can induce a chemical change in conductive solutions, such as when applied in electrolysis during facial treatments.

Galvanic current is often utilized in esthetic procedures for its ability to penetrate deep into the skin, allowing for treatments like iontophoresis, where active ingredients are introduced through the skin using electrical current. This method effectively enhances ingredient absorption and can help with conditions like hyperpigmentation or acne.

Alternating current, while also a form of electrical flow, changes direction periodically and does not specifically create a chemical reaction in the way galvanic currents do. Thermal refers to heat energy and does not pertain to electrical current types, while a circuit simply describes a complete path for electric flow and is not specific to either type of current or its effects on chemical reactions.
