Hi, Numbers can be very confusing - what '32% effective' means here, is not that Ultrashape Power will work in only 32 out of 100 individuals, but that it reduced 32 percent of fat for a given area of treatment. In other words, every person undergoing Ultrashape can see a reduction of upto (a maximum of ) 32% or one third of their fat reducing. Comparing other devices in the fat reduction domain, 32% reduction is very good indeed. That said, the question of how effective this procedure will be for YOU - if YOU will be able to achieve all of that 32% is dependent, firstly on your doctor - who assesses you and then decides how many FTZ for how much area, then your procedure technician or nurse that performs the procedure, and how much of wastage he/ she is able to prevent, and finally your body. An added point is the protocol itself -in my practice, we do not always follow the 2 week protocol. If a client/patient is okay with longer intervals, I prefer about 4 weeks (to upto 6 weeks for the arms) to help with better outcomes, and also to reduce the FTZ s required. In my practice as I am assuming with most users of USP, all (100%) of individuals have responses, with the best at around 45% reduction (yes, possible with some good customization) and the least at 21% (arms again). So a lot is dependent on technique here (compared to Coolsculpting), and your doctor needs to be able to customize a plan specifically for you. Good luck!
