What is the primary function of iontophoresis?

1. Aids in exfoliation of dead skin cells

2. Penetrates products into the skin

3. Stimulates collagen production

4. Improves blood circulation

The correct answer is: Penetrates products into the skin

The primary function of iontophoresis is to penetrate products into the skin. This technique utilizes a mild electrical current to help drive specific ingredients deeper into the epidermis, increasing the efficacy of the active ingredients in topical formulations. By enhancing absorption, iontophoresis allows for more effective delivery of serums and other beneficial substances, potentially leading to improved skin texture, hydration, and overall appearance. While exfoliation, collagen stimulation, and improved blood circulation are important aspects of esthetic treatments, they are not the main focus of iontophoresis. The exfoliation of dead skin cells is typically achieved through physical or chemical means rather than through the electrical process of iontophoresis. Similarly, while collagen production and blood circulation can be influenced by various treatments, iontophoresis specifically targets transdermal delivery of products, which is why the correct answer focuses on its role in penetration rather than these other effects.
