What is the name of the process used to force acidic substances into deeper tissues using galvanic current?

The process used to force acidic substances into deeper tissues through galvanic current is known as cataphoresis. This technique utilizes a direct current to enhance the penetration of acidic products into the skin, which can help in various skincare treatments.

Cataphoresis facilitates the movement of cations (positively charged ions) into the skin, allowing for more effective absorption of ingredients that may be beneficial for treating certain skin conditions. This is particularly useful in esthetics for delivering active ingredients that target specific skin concerns.

While iontophoresis is a broader term that refers to the use of electrical current to introduce ions into the skin, cataphoresis specifically addresses the movement of acidic substances. Electrophoresis, on the other hand, is a more general term for any process that uses electric charges to move particles, and sonophoresis involves using ultrasound waves to enhance product absorption, rather than galvanic current. Each of these processes has its unique applications, but for the scenario described, cataphoresis is the correct term.
