What treatment introduces water soluble treatment products into the skin?

1. Microdermabrasion

2. Iontophoresis

3. Dermaplaning

4. Laser therapy

The correct answer is: Iontophoresis

Iontophoresis is a treatment method that utilizes a mild electrical current to introduce water-soluble products into the skin effectively. This process enhances the absorption of active ingredients, making it an effective technique for delivering hydration and other beneficial treatments deep into the skin layers. The mechanism involves placing an ionizable product on the skin’s surface, which is then driven into the skin by the electrical current. This technique allows for a more precise and controlled application of ingredients compared to traditional topical methods. By utilizing the principles of electromagnetism, iontophoresis improves not only the penetration of ingredients but also helps promote increased circulation and tissue repair. Other methods like microdermabrasion or dermaplaning primarily focus on physical exfoliation rather than product introduction, and while laser therapy can aid in skin rejuvenation, it does not specifically facilitate the infusion of water-soluble products into the skin.
