Produced. Energy reaches the root of the hair follicle solely through melanin. Skin and red blood cells have a similar absorption Coeff icient as melanin and therefore also absorb the high levels of energy produced by the laser and ipl methods. Shr technology, on the other hand, utilizes the melanin path only partially (50%)., and combining in-motion technology, Gently warms the skin helping penetrate down to the follicles which produce hair growth. Research has shown that a slower, but longer heating process is considerably more effective for permanent hair removal than high and short levels of energy. Therefore, when using shr, the device is passed over the tissue multiple times (in motion) using low energy but a high rate of repetition (up to 10hz, i.E. 10 times per second) instead of using the traditional method with single, highenergy 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 of time to a comfortable temperature of 45¡ã celsius.
