What does cataphoresis do?

Cataphoresis is a method that utilizes galvanic current to introduce substances into the skin, typically for therapeutic purposes. One of its primary functions is to calm or soothe nerve endings, which helps to reduce sensitivity or irritation in the skin. By delivering a mild electrical current, cataphoresis can facilitate the absorption of calming agents, such as anti-inflammatory or soothing ingredients, directly into the skin. This process promotes relaxation and can alleviate any discomfort, making it particularly useful in treatments for sensitive skin conditions.

The other options focus on different skin care techniques or treatments that do not align with the specific function of cataphoresis. For instance, opening pores and increasing blood flow are typically associated with methods like steaming or massage rather than the relaxing effects of cataphoresis. Removing dead skin cells is more aligned with exfoliation processes, which also exist apart from the objectives of cataphoresis. Therefore, the ability of cataphoresis to calm or soothe nerve endings is a distinctive characteristic of this technique in esthetics.
