Since abdominal skin is not thin, isn't it a waste to use the 1.5mm Ultherapy transducer on it?
Had Ultherapy done to small square around my belly button and they used 1.5 and 3.5. Going to another place that will use 3.5mm and 4mm for my flanks. Why did first place bother with 1.5? Is it cheaper for them?
