Which type of current is primarily used in electrical facial treatments for its therapeutic properties?

The use of alternating current in electrical facial treatments is favored for its therapeutic properties due to its ability to generate heat and stimulate tissues. This type of current periodically changes direction, which helps improve blood circulation and promotes cellular repair and rejuvenation. Additionally, alternating current can be modulated to produce different therapeutic effects on the skin, such as stimulating muscle contractions or enhancing product penetration.

Using alternating current, estheticians can effectively administer various techniques, including facial stimulation and relaxation, making it versatile for different facial treatments. It is often utilized in devices like microcurrent machines, which are designed to lift and tone facial muscles while enhancing skin texture and tone.
