What is the primary purpose of iontophoresis in cosmetology?

The primary purpose of iontophoresis in cosmetology is to force cosmetic ingredients deeper into the skin. This process involves the use of a mild electrical current to enhance the penetration of active ingredients, allowing them to reach deeper layers of the skin where they can be more effective.

By utilizing this technique, practitioners can ensure that therapeutic substances such as vitamins, antioxidants, or hydrators are not just applied to the surface layer but are actually absorbed into the dermis, thereby maximizing their efficacy in promoting skin health and appearance. This method is particularly beneficial in treatments aimed at addressing issues like aging, dryness, or other skin conditions that require deeper intervention.

Other options, such as exfoliating the skin or toning facial muscles, do not accurately capture the specific function of iontophoresis, as these actions are achieved through different techniques and methods in cosmetology. Hydrating the skin can result as a secondary effect of introducing moisturizing ingredients into the deeper layers, but the defining characteristic of iontophoresis remains its role in enhancing ingredient absorption.
