What key process does iontophoresis facilitate?

Iontophoresis is a technique used in aesthetic treatments that involves the application of a mild electrical current to facilitate the penetration of various therapeutic products into the skin. This method enhances the absorption of active ingredients, enabling them to reach deeper layers of the skin than they would with topical application alone. By using this electrical current, iontophoresis allows for the enhanced delivery of medications, serums, or other beneficial compounds, making it a popular choice in skin care treatments.

The focus of iontophoresis is not primarily on stimulating blood circulation, punching skin layers, or reducing bacteria, which are associated with other processes and techniques in aesthetic practice. Instead, its main advantage lies in increasing the efficacy of topical products through deeper penetration, thus maximizing the benefits for the skin.
