Ultherapy or Silhouette soft face lift (threads)?

Thank you for your question. Both are good treatments in their own right, both safe in the right hands and both provide a good but modest lifting result. I am the UK trainer for Silhouette soft lift. In the right hands Silhouette soft thread lifts can give great results but for patients with moderate facial laxity I rarely perform silhouette soft without combination with other treatment - most commonly dermal filler but we now offer both ultherapy and thread lift in combination where more of a lift is required - called "The Dr Leah Lift".We have conducted trials on the combination method of Ultherapy followed by silhouette soft threads (we are publishing our case study findings at present) but generally the results tend to be much more dramatic when both treatments are combined (albeit 3 months apart - we perform Ultherapy and then insert threads 3 months later). Our findings were that the Best results are 6 months after Ultherapy and 3 months after silhouette soft threadlift and they tend to last a full 18-24 months (this longevity of result is something we were struggling to achieve with either of the treatments in isolation).We have offered Thermage in the past but found Ultherapy to give better results. For neck we are now trialling ultherapy followed by a treatment called profhilo and early outcomes for that combination treatment are very good, will update further on this when our mid and long term data is available. Both ultherapy and silhouette soft thread lift's are safe and effective if performed by a skilled practitioner. For more dramatic results a combination method may be worth discussing with your physician. Good luck and I hope this helps,

I have been performing non-surgical facial tightening procedures in my NYC practice for two decades and have seen an increasing number of procedures developed in the last few years. I have used radiofrequency tightening including Thermage, Pelleve, ThermiSmooth and the ultrasound energy device, Ultherapy. None of these procedures will cause the same amount of lifting in someone who needs a facelift but many patients aren't yet willing to undergo surgery. An in-between technology, called ThermiTight,  involving local anesthetic injected before delivering radiofrequency with a small rod underneath the skin, does provide more tightening than these external non-invasive procedures but does cause more swelling and often bruising for a week or so. Even with ThermiTight, we have found that in order to help raise the jowl, suture lifting with Silhouette sutures, called InstaLift, is often needed to be done along with the ThermiTight. Those patients who have heavy large jowls will not see much of a difference and I tell them that a facelift is their best option for a good aesthetic result.In general, one can learn from the above, that for some patients it may not be an appropriate decision to have either Ultherapy or Silhouette Instalift, rather, which non invasive tightening procedure should be done along with InstaLift. Certainly, some patients only need Ultherapy or ThermiSmooth but those with jowls that are hanging over the jawline might consider InstaLift as well.The information provided in Dr. Shelton's answer is for educational purposes only and is not intended to constitute medical advice.  The information provided should not be relied upon as a substitute for consultations with a qualified health professional who may be familiar with your individual medical needs.

Ultherapy is the only noninvasive facial skin lifting technology that is FDA approved. Variations of the threadlift have been around for some time but it is a surgical procedure and I have not been impressed with the results. Better to improve the collagen under your skin with microfocused ultrasound using Ultherapy.
