What is the primary action of tesla (high-frequency) current?

The primary action of Tesla (high-frequency) current is to produce heat. This thermal effect occurs when the high-frequency electrical current passes through the tissues, generating warmth. This heat can help to stimulate metabolic processes within the skin, increasing blood circulation and promoting a revitalized appearance.

While other actions, such as enhancing blood circulation and moisturizing the skin, can indirectly result from the heat generated, the direct and primary effect of Tesla current is the heat production itself. This heat can also aid in the absorption of products applied to the skin during treatments. The use of high-frequency current is commonly associated with various skincare benefits, but it is the heat generation that serves as the foundation for these therapeutic effects.
