Which hair removal method uses a high frequency alternating oscillating current?

Thermolysis is the hair removal method that utilizes a high frequency alternating oscillating current. This process works by generating heat through the electrical current, which effectively destroys the hair follicle without damage to the surrounding skin. The high frequency used in thermolysis allows for rapid treatment times and can be particularly effective for finer hair types.

In contrast, galvanic hair removal relies on a direct current to produce a chemical reaction that destroys the hair follicle, which is a different mechanism altogether. Laser hair removal employs targeted light energy to disable hair follicles, and depilation typically involves the mechanical removal of hair from the skin's surface, such as through shaving or using depilatory creams, rather than targeting the follicle itself. Understanding these differences highlights why thermolysis, specifically the use of high frequency alternating currents, is distinct in its approach to hair removal.
