Thermolysis is a process that uses heat to destroy hair follicles and is considered an effective permanent hair removal method. The heat is generated by either a diathermy machine or a laser, and is applied to the skin for a specific amount of time. The heat damages the hair follicle, which prevents future hair growth.
Thermolysis is most effective on small areas of the body, such as the upper lip, chin, and bikini area. It can also be used on larger areas, but the treatment time will be longer and the results may not be as consistent.
