I am 28 and have a nearly underweight BMI but have heavy tissue (a mixture of fat, subdermal fat and other tissue) along my jawline and under the chin. I have already had 3x Morpheus8 and have good skin laxity. I have a healthy lifestyle. FYI my underlying jawbone is NOT square - it's more oval shaped. The squareness you can see in the pics is all tissue!! A doctor I spoke to said Profound could be a good option for me. What do other people think?
