What is the primary purpose of iontophoresis in skin treatment?

The primary purpose of iontophoresis in skin treatment is to introduce products into the skin. This technique utilizes a low-level electrical current that helps to enhance the penetration of various active ingredients in skincare products. By using iontophoresis, the skin’s barrier function can be temporarily altered, allowing for deeper delivery of these ingredients, which can lead to more effective treatments.

Other options, while related to skin treatments, do not capture the specific function of iontophoresis. Removing dead skin cells is typically achieved through exfoliation methods, and while hydration and improving skin texture are important aspects of skincare, these effects can be achieved through various treatments other than iontophoresis. Stimulating hair growth is not a primary function of this technique and falls under different treatment modalities aimed at addressing hair-related concerns. Thus, focusing on the delivery mechanism provided by iontophoresis highlights its unique role in enhancing product efficacy within skincare regimens.
