What machine has an electrochemical effect?

1. Ultrasound

2. Vibrational massager

3. Galvanic

4. High-frequency

The correct answer is: Galvanic

The machine that possesses an electrochemical effect is the galvanic device. This type of equipment operates by generating a direct current, which can penetrate the skin and create a variety of beneficial chemical reactions within the tissues. The electrochemical effect refers to the ability to induce a chemical change by stimulating cells through electric currents, allowing for improved penetration of active ingredients and promoting cellular activity and circulation. In esthetics, galvanic treatments often involve the use of Iontophoresis, which facilitates the introduction of products into the skin, enhancing their effectiveness. This feature distinguishes galvanic machines from others that rely primarily on different types of energy or mechanical stimulation. Ultrasound, vibrational massagers, and high-frequency machines utilize sound waves, vibrations, or electromagnetic energy rather than direct electric current to achieve their effects, thus lacking the specific electrochemical interaction that galvanic machines provide. Each of these machines serves unique purposes but does not engage the skin at a chemical level in the same manner as galvanic devices.
