What does cataphoresis involve?

Forcing alkaline substances into the skin
Forcing acidic substances into tissues with a negative electrode
Forcing acidic substances with a positive electrode into tissues
Infusing negative products using galvanic current

The correct answer is: Forcing acidic substances with a positive electrode into tissues

Cataphoresis refers to a process in which acidic substances are introduced into the tissues of the skin using a positive electrode. This is an electrotherapy technique often used in esthetics to deliver benefits such as enhanced penetration of skincare ingredients and improved treatment outcomes. In this method, the positive electrode helps to drive the acidic products into the skin, taking advantage of the principle that similar charges repel and opposite charges attract. This means that the positive charge of the electrode will push the negatively charged ions in the acidic solution into the skin's tissues more effectively. Understanding the use of current in various forms of electrotherapy, like cataphoresis, is essential for practitioners, as it informs them about the mechanisms of ingredient delivery and the overall effectiveness of treatments they provide.
