What type of currents does microcurrent therapy emit?

1. High frequency electrical currents

2. Direct electrical currents

3. Low voltage electrical currents

4. Pulsed electromagnetic fields

The correct answer is: Low voltage electrical currents

Microcurrent therapy emits low voltage electrical currents, which are utilized in various cosmetic and therapeutic applications. These currents are typically in the microampere range, which is considerably lower than traditional electrical currents used in other modalities like high-frequency treatments. The low voltage nature of microcurrent therapy allows for safe and effective stimulation of the facial muscles and tissues, promoting healing, enhancing circulation, and improving overall skin tone and texture. This low voltage characteristic is crucial, as it enables the treatment to closely mimic the body's natural electrical signals, facilitating cellular repair and regeneration without discomfort or damage to the tissues. The gentle nature of these currents makes them suitable for a wide range of skin types and conditions, allowing estheticians to provide a customized treatment that enhances the client’s results.
