What type of current is a galvanic current?

Alternating current
Direct current
Mixed current
Pulsed current

The correct answer is: Direct current

Galvanic current is classified as direct current, which means it flows consistently in one direction. This type of electrical current is significant in esthetics because it produces chemical reactions in the skin during treatments. When a galvanic current is applied, it can assist with the penetration of products into the skin and can also help in the process of desincrustation and iontophoresis. The continuous flow of this current allows specific therapeutic effects, making it a valuable tool in various skin treatments. Understanding the properties of galvanic current is crucial for estheticians, as it informs the appropriate applications and techniques to achieve desired results for their clients.
