Hi Thanks for your interesting but challenging question. without any pictures is not possible to give you a specific answer because it is also important a detailed assessment of the area to be treated, your skin e.g. elasticity, muscle tone, smoking status, age, history of significant weight fluctuations etc. I completely agree with you that there are so many devices in the market and every company has a story and in general each device can deliver the energy slightly different than any of the others. In addition each device can reach and treat different layers of the skin. The most common energy-based devices for tighter and/or smooth the skin are Radiofrequency, Laser, Ultrasound, Microneedling. To achieve optimal results, it would be better to uses devices in combination. Current literature suggests that radiofrequency (RF) energy shows objective skin tightening / tissue contraction. However non-surgical skin tightening is for patients with mild to moderate skin laxity. For patients with severe skin laxity then surgical skin removal is a more suitable option. it is important that the doctors that offer these energy based devices are very clear with patients about what the devices can and can not achieve. in my clinical practice I have experience in Vaser, Renuvion, Face/Neck/bodytite and Morpheus 8. I usually combine 2 devices to have better results. Vaser Liposuction is for fat removal and body contouring. The combination with J plasma- Renuvion or Bodytite will allow to increase the probability of skin tightening. 1) Renuvion requires only 1 session. 2) Bodytite requires 1 session in combination with Morpheus 8 (3 sessions 4 to 6 weeks apart). Morpheus 8 involves microneedling and Radiofrequency and could be quite discomfort at high level of energy for better results. For this reason, in my clinic , Morpheus 8 is performed by a surgeon with experience in local anesthetic infiltration to reduce the discomfort. Before to consider any surgical option I would recommend first to start with non surgical/ less invasive option however the results are never guarantee because each patient is different and the results varies patient to patient. I would recommend to make an appointment with amsurgeon expert in body contouring and skin tightening for a medical assessment in order to make a bespoke treatment plan. Hope this helps, Best Wishes, Dr Giuseppe Fiore
