Iontophoresis refers to a technique that utilizes a mild electrical current to enhance the penetration of products into the skin, particularly targeting the deeper layers of the epidermis. This method is commonly used in esthetics to deliver beneficial substances, such as hydrating agents, vitamins, or anti-aging compounds, directly where they can be most effective.

By using this technique, estheticians aim to improve skin health and appearance by nourishing these deeper skin layers, which can contribute to improved texture, hydration, and overall skin vitality. Customers seeking treatments for conditions like dryness or signs of aging often benefit from the enhanced absorption provided by iontophoresis, making it a valuable tool in the esthetician's repertoire.

While exfoliation, hair removal, and acne reduction are important techniques used in esthetics, they do not specifically involve the electrical current necessary for iontophoresis and do not focus on delivering nutrients deeper into the skin as this method does.
