A There could be many answers as to why results were not seen.
Maintaining a healthy diet and regular exercise can help emphasize the results of TruSculpt 3D making them more prominent. TruSculpt 3D does shrink the fat in the selected treatment area but may not be noticeable if diet and exercise aren't consistent.
Also it depends on the temperature reached during the treatment. It could be that the optimal temperature wasn't reached and therefore didn't penetrate the fat layer deep enough.
At our practice, we offer our clients a full body scan that measures the amount of fat everywhere on the body. This allows for us and our client to see the difference 12 weeks after treatment. Pictures are also taken before, at 6 weeks, and at 12 weeks. This helpfully demonstrates the physical external changes the body has gone through in the 12 week process.
At the 12 week mark, if not enough difference is achieved; we perform a second treatment to target the stubborn fat area.
