Question

Galvanic devices emit ............. to bring some chemical changes in the skin.

• A. Alternating Current (AC)
• B. Direct Current (DC)
• C. Combination of AC and DC
• D. Faradic current

Hint:

Tip: Remember — galvanic = DC, high frequency = AC.

Answer 1

The Correct Option is B

Galvanic devices are commonly used in professional facials for deep cleansing and product infusion.
These devices work by using Direct Current (DC) which flows in one direction and creates chemical reactions on the skin surface.
DC current is used for two main procedures: desincrustation, which deep cleanses pores, and iontophoresis, which infuses active ingredients.
Alternating Current (AC) changes direction repeatedly and is not used for galvanic treatments.
Faradic current is used for muscle toning treatments, not for galvanic facials.
A combination of AC and DC is not applicable in this case — only DC is used.
Therefore, galvanic devices emit Direct Current (DC).
