The main characteristic of Tesla current is that it is an alternating high frequency current. This type of current is primarily used in electrotherapy treatments and is known for its stimulating and energizing effects on the skin and underlying tissues. The high frequency of Tesla current is significant because it allows for deeper penetration and enhances various physiological processes such as circulation and metabolism, which are beneficial in esthetic treatments.

In addition, alternating currents like Tesla have the ability to oscillate back and forth, which can create thermal effects in the tissues, aiding in different skin treatments, such as those aimed at improving skin texture and healing. This property distinguishes it from other types of currents, like direct current, which flows in a single direction and has different applications and effects.

Understanding that Tesla current operates at a high frequency allows estheticians to effectively use it in practices involving skin rejuvenation and other therapeutic techniques, making it a vital component in the esthetics field.
