Using a patented technology, SHR permanently destroys hair follicle by using low fluence, repetitive light pulses, targeting the susceptible hair follicles. Compared to IPL and Laser light-based hair removal systems, which fire around 2-4 high-powered shots into each hair follicle, SHR fires a minimum of 20-30 shots into each follicle. This can be described as the difference between the speed of an automatic machine gun using SHR, to a single rifle shot using traditional IPL. Additionally, the revolutionary “ in-motion ” technology gradually and transiently heats up the targeted hair follicles, making this treatment virtually painless, especially appreciated by customer with darker , thicker hair on sensitive areas like back .
