Cryolipolysis Machine Applicators suction

I’ve done CoolSculpting before in my stomach and got great results. This time around I found a place without the brand name but still cryolipolysis machine and did both inner and outer tights. My concern is that with the non-cool sculpting machine I noticed the applicators would suck in and out at a regular pace through the 45 minute session. With CoolSculpting it was a constant suction of the skin. Should I be concerned it won’t work? Thanks!
