A client presents with sensitive, dehydrated skin and requests a facial treatment focusing on hydration and soothing. Which of the following electrical modalities would be MOST appropriate to use for product penetration without causing irritation?
- AMicrocurrent
- BHigh-frequency current
- CGalvanic current (Iontophoresis)
- DVacuum suction
Show answer & explanationAnswer & explanation
Correct answer: C. Galvanic current (Iontophoresis)
Galvanic current, specifically iontophoresis, is ideal for infusing water-soluble products into the skin, making it suitable for sensitive and dehydrated skin as it enhances product penetration without harsh stimulation.
Why the other options are wrong
- A. Microcurrent primarily focuses on muscle toning and lifting, not optimal for product penetration for hydration.
- B. High-frequency current is stimulating and can be drying; it's not ideal for sensitive, dehydrated skin.
- D. Vacuum suction is used for deep pore cleansing and lymphatic drainage, not for gentle product infusion.
