Which process involves forcing acidic substances into deeper tissues?

The process that involves forcing acidic substances into deeper tissues is known as cataphoresis. This technique uses a direct electric current to drive positively charged ions of acidic substances into the skin. As a result, this method promotes enhanced absorption of these ingredients, making it beneficial for various skin treatments.

Cataphoresis specifically takes advantage of the skin’s electrical properties and is often utilized in professional esthetic treatments to promote healing, hydrate the skin, or deliver specific therapeutic agents more effectively. By leveraging electrical current, cataphoresis can increase the permeability of the skin's layers, allowing for deeper penetration of the beneficial ingredients contained in the chosen acidic substance.

In contrast, other processes listed, such as phoresis and anaphoresis, involve different mechanisms of ion movement or skin penetration, which do not specifically focus on delivering acidic substances. For example, phoresis generally refers to the broader act of guiding substances across the skin using electrical currents, while anaphoresis specifically involves the movement of negatively charged ions into the skin. Desincrustation is primarily used to prepare the skin for extraction by emulsifying debris and oils, rather than focusing on introducing acidic substances.
