1. How does HIFU  work?
The  device uses targeted ultrasound technology to direct sound waves through the skin to the deeper layers and structures beneath the skin.  Similar to the use of ultrasound to visually see a fetus on a screen during a pre-natal appointment, the layers of skin and tissue are able to be seen and specifically treated during ultherapy.  Ultrasound waves generate heat, which is directed at the deepest layers of the skin.  As the layers warm, the patient’s own collagen is stimulated, which in turn naturally activates the production of new collagen.  This new collagen provides volume to lift and  tighten the skin.   Procedures typically take 30-60 minutes.

2. What kind of results can I expect?
With just one treatment, the regenerative process is initiated, but the full effect will build gradually over the course of two to three months. Some patients may benefit from more than one treatment. Visible effects include a lifting and toning of loose skin. In the FDA clinical trial for instance, nine out of ten patients had a noticeable, significant lift of the brow line. This resulted in reduced skin laxity on the eyelid nd a more open, youthful look to the eyes overall. Patients reported firmer, better-fitting skin in other areas of the face and neck as well. There is also an invisible result from the procedure with the creation of new collagen, which gives the skin its youthfulness.

3. How soon are results seen? How long do the results last?
Most clients report an immediate improvement in overall appearance, but full results take 2-3 months as the collagen needs this time to fully develop.  Some benefit from more than one treatment.
As with any non-invasive procedure, HIFU results will not be as dramatic or as long-lasting as facial surgery.  However, most clients report results lasting anywhere more than 15 months.

4. What are the benefits of HIFU ? How does it compare to other skin tightening devices such as Thermage?
With HIFU, there’s no surgery, there’s no cutting, there’s no scar, there’s no down time.  For those clients who want a true lunchtime procedure without recovery, HIFU may be a good option.
While not a scientific poll, the reviews on the cosmetic procedure community web site, , are as follows (as of January 4, 2012):

Thermage = 39% say worth it,  242 total reviews: 94 worth it, 140  not worth it, 7 not sure
HIFU = 84% say worth it,  110 total reviews: 76 worth it, 15 not worth it, 29 not sure (most waiting for 2-3 month period to end)

5. Does HIFU  hurt?
Every person has a different pain tolerance so it’s no surprise that while some people report just a mild warming sensation, others report quite a bit of discomfort.  Patients might benefit from the use of over-the-counter oral pain medications to make the procedure more comfortable.  For the comfort and satisfaction of our clients we utilizes the Zimmer cryo cooled air system during procedure.

6. How much does HIFU treatment cost?
Typical  treatments range from $1,000 to $3,500 depending on the area being treated. Treatment areas can include, eyes, forehead, mid face, full face & neck, neck and /or chest.

7. What can I expect afterwards?
You are able to return to your normal activities right away, and there are no special measures you need to take. Your skin may appear a bit flushed immediately after the treatment, but any redness should disappear within a few hours. It is not uncommon to experience slight swelling for a few days following the procedure or tingling/tenderness to the touch for a few days to weeks following the procedure, but these are mild and temporary in nature. There is the possibility of other less common post-procedural effects, such as temporary small areas of bruising or numbness, which your clinician will review with you.
