Would PrecisionTx, Ultherapy, or Silhouette threads be best for my wrinkled neck? (Photos)

Thanks for your question. Silhouette sutures would not be helpful here. Precision Tx is an option, or a similar procedure called "FaceTite" which uses radiofrequency energy rather than laser energy. I would suggest combining FaceTite with Morpheus8 so that you are heating both superficially and on the deeper plane. These two treatments operate off of the same platform so it's easy to find doctors who perform both. Precision Tx would tighten but not help with smoothing the surface and it appears you could benefit from both tightening and smoothing. If you need a "no downtime" option then consider Sofwave which is the more advanced form now available for micro-focused ultrasound (and it provides much better smoothing than the older version, Ultherapy). Sofwave will certainly smooth and tighten, and with no downtime, but likely not as much as the combo treatment I just outlined. I hope that helps!

In your case you will need a combination of treatments to achieve maximal results. I will start with diluted radiese to improve skin texture and laxity and then if you still need more ( MINT PDO THREADS)
