Which unit is used to measure current intensity in facial treatments?

Explanation:
Current intensity in facial treatments is expressed in milliamperes because the devices deliver very small currents. The ampere is the standard unit for current, but skincare equipment uses milliampere levels to keep the treatment safe and comfortable. Volts measure the electrical pressure, and ohms measure resistance, so they don’t describe how strong the current is. Since these treatments require precise, low-strength current, milliamperes is the appropriate unit.
