Everyone want SMP should be permanent so that there is no need of go to clinic for touch up.
Above link claims for permanent SMP. So why most of the information on internet says that SMP fades with time and there is need of touchup after years.
As above link says , there needles are special . Can any doctor in the world can use these needles for permanent SMP to patients? If yes then what is the procedure , means how to take consent from patent agency. ?
