What type of electrical current is commonly used in electrotherapy procedures?

Galvanic current is commonly used in electrotherapy procedures due to its unique properties and effects on the skin. This type of current is a form of direct current (DC), which flows steadily in one direction, making it effective for various treatments such as iontophoresis, which involves the introduction of products into the skin using a charged electrical current.

Galvanic current also facilitates deep cleansing by helping to emulsify and lift dirt and oils from the pores. Additionally, it has a stimulating effect on circulation and can enhance the penetration of active ingredients during facial treatments. The ability to produce chemical reactions, such as ionization, makes galvanic current particularly valuable in esthetics for both rejuvenation and therapeutic applications.

While direct current, magnetic current, and pulsed current may have their uses in specific contexts, galvanic current is favored in electrotherapy due to its dual capability to cleanse and treat simultaneously, which is crucial for effective esthetic practices.
