Question: 1 / 400

What is the primary use of galvanic current in esthetics?

Rejuvenating the skin

Driving solutions deeper into the epidermis

The primary use of galvanic current in esthetics is centered around its capability to drive solutions deeper into the epidermis. This process utilizes a technique known as iontophoresis, where the electric current helps to facilitate the penetration of various therapeutic products, such as serums or gels, into the skin.

When galvanic current is applied, it causes the active ingredients to become ionized. Since like charges repel and opposite charges attract, this ionization carries the product deeper into the skin layers, enhancing its effectiveness. This is particularly beneficial for treatments aimed at improving hydration, delivering nutrients, or treating specific skin concerns.

The other functions mentioned, such as rejuvenation, skin cleaning, and stimulating blood circulation, are secondary effects that might occur alongside the primary action of driving solutions into the skin but do not encapsulate the main purpose of using galvanic current in esthetic practices.
