Which effect is created when electric current travels through a water-based solution and onto the body?

When electric current travels through a water-based solution and onto the body, the primary effect created is electrochemical effects. This phenomenon occurs because the electric current interacts with the ions present in the solution, leading to various chemical reactions. As a result, this effect can facilitate processes such as iontophoresis, where active ingredients are driven into the skin using electricity, enhancing their efficacy in treatments like skincare or pain relief. The electrochemical effect is crucial in many esthetic treatments, as it allows for targeted delivery of substances and can aid in therapeutic outcomes.

The other effects mentioned—thermal, magnetic, and mechanical—do not directly pertain to the interaction of electric current with a solution in the same way. While thermal effects relate to heat generation, magnetic effects involve magnetic fields rather than electrical currents, and mechanical effects pertain to physical movement or vibration. These aspects are not the primary focus when discussing the impact of electric current on a water-based solution in the context of esthetics.
