A facial treatment device that uses direct current with low voltage and high amperage is known as:

• A. Galvanic
• B. High Frequency
• C. Microdermabrasion
• D. Light-emitting diode device

Answer: (A)

This question tests understanding of how facial treatment devices are defined by the type of electrical current they use. A device that uses direct current with low voltage and high amperage is galvanic. Direct current means electrons flow in one direction, unlike alternating current. In galvanic treatments, there are two poles on the skin—one positive and one negative—and the current drives ions from a conductive solution into or out of the skin. The low voltage keeps the setup safe, while the higher amperage provides enough current to move these ions effectively. This ion movement enables effects like desincrustation, where an alkaline solution is driven into the pores to soften and break down sebum and debris, and iontophoresis, where active ingredients can be pushed into the skin with the corresponding charge. This approach is distinct from high-frequency devices, which use alternating current to create heat and sterile by-products; microdermabrasion, which relies on mechanical exfoliation; and LED devices, which use light therapy rather than electrical current to achieve effects.
