I am 42 with slightly relaxed skin on my jawline & under my chin. I've read about Ultherapy and am considering it. Some of the published pics look promising, some not so much. I've read that 1.7mm (which is smaller than the thickness of 2 dimes put together) is the avg lift in the eyebrow area, though I want lower face lifting. Please put into context how much visible lift a "younger" less saggy patient can expect?
