Traditional Laser or IPL Technologies employ short impulses of approximately 2-300 milliseconds, applying a vast amount of energy (12-120J/cm2).
Energy is transported to the hair root through melanin, where warmth of 65-72° Celsius is produced. Energy reaches the root of the hair follicle solely through melanin.
Skin and red blood cells have a similar absorption coefficient as melanin and therefore also absorb thehigh 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 forpermanent hair removal than high and short levels of energy.
Therefore, when using SHR, the device ispassed 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, 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 of time to a comfortable temperature of 45° Celsius
