This has nothing to do with the machine. I wouldn’t switch to the Soprano because of it. The issue here is twofold: density and coarseness of the hair and settings.
Also, you should be using a numbing cream like EMLA that is used in hair removal, applied about an hour before the treatment.
On a male face where the hair is coarse, GentleYAG would probably be the best way to go to start. When the hair gets finer, they can switch to GentleLASE.
Soprano is not going to do anything different unless you use much lower settings on it in comparison, which defeats the purpose.
Also, even with numbing cream, I would expect some pain. You’re killing dense coarse hair. If you’re not willing to do it, LHR may not be for you. There is no point of looking for painless or almost painless treatments on this area. This won’t happen unless they’re using ineffective settings.
Also, once again, due to the density of the hair, I would expect some side effects like redness and a bit of sweeling for a few days. It’s only an issue if it lasts more than a few days. Icing the area and using cold aloe vera and witch hazel will help.
