Thermolysis method or Shortwave diathermy method or radio-frequency method - in this technique alternating current is passed through the needle which heats up the needle inserted into the root of the hair. The heated needle produces bubbles of the water which loosens the root and kills the germinative cells of the hair root to produce permanent removal of the hairs. This method is less effective then the Galvanic method. Thermolysis was developed in the 1920s and first reported in medical literature by Henri Bordier. A thermolytic epilator is essentially a radio transmitter, usually with an output of about 0-8 watts at a frequency of 13.56 MHz. RF energy emanates from the probe tip to tissue within about a millimeter. Thermolysis works by heating the hair matrix cells to about 48°C (118.4° Degree Fahrenheit), causing electrocoagulation. In this method, passage of a high-frequency current down the needle produces destructive heat in the follicular tissues by molecular vibration. This heat then destroys the hair structure and dermal papilla. Thermolysis is much faster than galvanic electrolysis and requires only a few seconds. In high-speed “flash” thermolysis the higher energy current is applied for only a fraction of a second. The flash method is best used with insulated needles, which protect the upper hair follicle and permit higher energy directly into the lower follicle. This method is not suitable for coarse hairs and may have a slightly higher risk of skin damage.
