Will Ultherapy help festoons or malar bags?

The deeper tissues of the malar crescent can be treated with ultrasound but thermi tight allows the surgeon to place the energy directly onto the swollen tissue unlike Ulthera that has to bypass the skin. With these treatments it may take up to 4-6 months to see the final results

Generally speaking, the ideal treatment for malar bags and festoons is blepharoplasty a surgical procedure. Nonsurgical treatments may improve this area, Ultherapy does help to a certain extent. Another procedure that is helpful is ThermiTight using radiofrequency microinvasive probe to treat this area.

You might get some tightening with the Ulthera for the festoons.  We have been using it for that, and some people do seem to get improvement.  But not everyone!  There are no downsides to giving it a try as there isn't much else that works well to decrease the festoons. Some of the other lasers such as fractionated CO2 or erbium may tighten it up a bit too. 

Thanks for the question, I have found ultherapy in my practice to be very useful for softening festoons and malar bags but are not ideal for fat reduction in the lower eyelids (for that surgery is still the best)GOOD LUCK

We've had some good  results treating festoons with Ulthera but are finding that Thermi smooth and Thermi Tight may be a better option since we are able to precisely set the temperature and identify the tissue layer being treated.  Which technique is best I find depends on the amount of skin laxity, bone structure, etc. often lifting the festoon with a non hydrophilic (water absorbing ) filler will lift and support the festoon and then Thermi smooth may be used to tighten the skin.

In short, yes, Ultherapy can be used for festoons and malar bags. It's difficult to predict the degree of improvement and so depending on the result you're looking for surgery may be a better choice. 

Without a picture it is difficult to say how bad your malar bags are, but in general, Ultherapy will not help that in most cases. Read the Ultherapy book on the link below:
