SHR
The multi IPL/RF system is a high powered Intense Pulsed Light (IPL) and Radio Frequency (RF) based multi treatment system.
The system features a highly effective SHR function for hair removal or reduction, via the system's SHR modality and specific 'SHR' handpiece.
SHR uses cooled flashlamps filtered at light wavelengths suited for specific hair colours and skin types, along with high pulse repetition rates and low energy levels. With this SHR technology, the skin can be painlessly massaged repeatedly between six to ten times, with gradual heating of the hair follicles, which absorb the light energy into the hair pigment to disable hair growth cells.
Laser and traditional IPL based hair removal technologies employ short impulses of approximately 2-300 milliseconds, applying a vast amount of energy (25-35 Joule on one square centimetre). Energy is transported to the hair root through melanin, where warmth of 65-75° Celsius is produced. Energy reaches the root of the hair follicle solely through melanin. However the latest SHR technologies as implemented in the EvoLux system's SHR modality and specific 'SHR' handpiece, use the melanin path only partially (50%). Additionally research has shown that a slower, but longer heating process is considerably more effective for permanent hair reduction than high and short levels of energy. Therefore when using SHR, the handpiece is passed over the skin multiple times using low energy but a high rate of repetition (up to 10 times per second) instead of using the traditional delivery method of single, high-energy impulses. Thus the hair melanin, as well as the tissue of the stem cells, is heated with low energy at a slow pace and over a longer period to a comfortable temperature of 45° Celsius.
