What uses cataphoresis to build up or nourish the deeper layers of the epidermis?

Galvanic
Microcurrent
Ionotohoresis
Ultrasonic

The correct answer is: Ionotohoresis

Ionotophoresis uses electric current to deliver nutrients deep into the layers of the epidermis. This is different from the other options, such as galvanic, microcurrent, and ultrasonic, which may have different uses or methods of skin care. For example, galvanic currents may be used for deep cleansing or reducing inflammation, while microcurrents are commonly used for muscle toning and lifting. Ultrasonic waves are used for exfoliation or product penetration. Therefore, ionotophoresis specifically targets feeding the deeper layers of the skin with essential ingredients.
