Which technique helps products penetrate deeper into the skin?

Iontophoresis is a technique that utilizes a low-level electrical current to enhance the penetration of active ingredients in skincare products into the deeper layers of the skin. This method works by applying a positive or negative charge to the electrodes, which helps to drive charged particles within the product through the skin barrier. The electrical current facilitates the movement of ions, allowing for deeper absorption and increasing the efficacy of the treatment.

While other methods like galvanic current, microdermabrasion, and ultrasonic therapy may also aid in enhancing skin treatment effects, they do not focus primarily on the ionic penetration of products in the same targeted manner that iontophoresis does. For example, galvanic current primarily focuses on the chemical reactions that occur in the skin and can promote product penetration but does not utilize the same ion-driving mechanism. Microdermabrasion is a physical exfoliation method, which removes dead skin cells but does not necessarily enhance product penetration beyond the surface level. Ultrasonic therapy typically employs sound waves to stimulate the skin, but its main function is not aimed at product penetration in the way that iontophoresis targets the movement of ionic substances.
