Does pressing the MiraDry handheld device against the skin affect efficiency? (photo)

Hi I just did my 1st procedure for Miradry and I will be doing a 2nd procedure shortly. I noticed good reduction in sweating but i noticed i still sweat along the outer regions of the underarm What is the difference between pushing in and NOT pushing in the hand-held device against the skin during the procedure, as it relates to certain areas of the underarm? Because my skin specialist sometimes pressed in the device against my skin and other times did not. Does this affect efficacy?
