I have used local anesthetic to lessen Ultherapy pain in my NYC practice with good results
This is not a question that can be answered with one answer.
It depends on how much local anesthetic is used and if the tissues are very swollen during the treatment vs. a small amount of anesthetic that doesn't change the thickness (temporarily) of the skin and soft tissues. On the other hand, making the area numb and allowing the patient to have a more thorough treatment can create a better result. If the tissues are temporarily more swollen from the anesthetic (if local injections in the treated area are done compared with regional blocks done away from the exact site) the doctor may be able to provide treatment with all transducers including the 4.5mm deepest. I have been able to accomplish this on the forehead and have had some excellent results of forehead lifting, whereas, without the local anesthetic filling out the forehead, the 4.5mm transducer is too deep as the forehead bone is closer to the skin's surface compared to the cheek and its underlying structures. This is an off-label use of the device and your physician should discuss it with you thoroughly. Also this changes a procedure that is thought not to have down time with a treatment that can have bruising and swelling afterwards from the injections.

Ask a doctor
Lidocaine, does it lessen the effects?
Lidocaine injections should not affect the results of the Ultherapy treatment, especially in the small doses given.
I think it is highly unlikely that lidocaine injections would alter your results. The only way I think it could alter it is if large volumes of tumescent anesthesia (dilute Lidocaine) were injected. Of course at this point in time their are no split face controlled studies.
Ultherapy and Lidocaine
The lidocaine nerve blocks should not have anything to do with the effectiveness of your treatment. It is designed to help your tolerance of the treatment.
Done right, it should affect results of Ultherapy
If lidocaine is used as a block, it's far enough from the treatment surface that it should not practically or theoretically affect results of Ultherapy.
Getting lidocaine blocks for Ulthera won't affect the results
Getting lidocaine blocks for the Ulthera shouldn't affect your results. It will allow for potentially more aggressive treatment so it actually might be better. I'm becoming a fan of Infini for skin tightening too. I've done Ulthera for 4 years and I think it might be better. Steve Weiner, MD
Anesthetic injections not needed for new Ultherapy protocol
It is theoretically possible that lidocaine injections might lessen the effect of Ultherapy by expanding the tissue space which would in turn lessen the density of the treatment sites. However, Ultherapy is done differently than it was until recently, with lower energy settings but better results. Most patients tolerate the treatment very well.
Don't need lidocaine for Ultherapy
Have done hundreds of cases and never used lidocaine and don't recommend it for Ultherapy as I don't thin you need it.
