Will ultherapy interfere with my existing facial fillers?

Ultherapy is not used over the areas of these
fillers and will not interfere with them. It is used on jawline, under chin,
neck, temples and lateral cheeks. Combining ulthera with other treatments, such
as fillers, is recommended to enhance the patient’s outcome and overall result.
That being said, we recommend waiting 2 weeks between fillers and Ulthera to
allow for proper settling. 

It is possible that the heat from the Ultherapy could accelerate the decomposition of the fillers a little bit. For the most part the areas treated by Ultherarpy and at the depths where the heat is being applied do not overlap the most common placements of filler. The Ultherapy is generally going to be done on the lower face, neck, and decolletage. Where most filler will be in the midface and lips. I have treated many patients with Ultherapy after they had already had filler injected and have yet to have a patient lose all of the volume from there filler or anything else drastic like that.Best of luck,

Ultherapy can tighten facial features, by delivering focused deep ultrasound energy to the dermis and connective tissues. But the energy might penetrate through certain fillers placed in the dermis prior to the Ultherapy treatment.  There is no clinical evidence that the Ultherapy treatment will ruin the longevity of the fillers placed in the dermis prior to the Ultherapy treatment.The information provided in Dr. Shelton's

Ultherapy doesn't negatively affect the facial fillers, in some instances it can help the fillers give more lift and collagen production (Sculptra).  Best, Dr. Emer.

Ultherapy is a  noninvasive skin lifting technology, fillers add volume, so in general they work well together because each addresses a different aspect of facial aging. However, it is possible that Ultherapy directly over fillers could have an effect, though this has not been studied specifically. Most of the time the areas needing volume with dermal fillers are not the same as where the Ultherapy would be applied.

It is inconclusive as to the affects of Ulthera and Hyaluronic acid (Voluma and Juvederm). When I have personally performed Ultrasound treatments, I encourage Ulthera first then follow up with filler. If filler has already been placed, Ulthera can be avoided on the cheek bones.

Filler
and Ultherapy are frequently combined with great results. Your question however is a good one, and one
that could use a little more research. But from experience I do not believe
that your existing facial fillers will be affected. The Ulthera is most frequently performed in
areas that are not directly over where the Juvederm or the Voluma are likely
placed.

Read the Ultherapy book on the link below.Ultherapy is sometimes used with Sculptra and the dermatologist who uses this technique has coined the term "Sculptherapy" as he has shown that it increases collagen deposition further.Facial fillers are not detrimentally affected by Ultherapy. 

Areas such as the neck and jawline should present no problem.  If treatments are performed over fillers at sufficient depth, there may be some decreased longevity, but from a safety perspective, there is no issue.
