What is the constant low level and direct electric current used in facial treatments known as?

The constant low level and direct electric current used in facial treatments is known as galvanic current. This form of current is particularly important in esthetics for facilitating various skin treatments. Galvanic treatments can help in the process of iontophoresis, which allows for the penetration of products into the skin by using electric current. It also aids in enhancing circulation, promoting lymphatic drainage, and aiding in the cleansing of the skin.

The properties of galvanic current make it useful for achieving desired results in facial treatments, such as deep cleaning and hydration of the skin. By utilizing a steady and direct flow of electricity, practitioners can ensure a consistent and effective application of the treatment.

In other types of currents mentioned, like faradic and Tesla, the applications differ; faradic is known for stimulating muscle contractions, while Tesla current incorporates high-frequency electrical energy for various skin treatments. Pulse refers to intermittent currents, which have different applications and characteristics compared to the continuous nature of galvanic current. Hence, the unique attributes of galvanic current make it the correct answer for this question regarding facial treatments.
