I am not aware of any negative effect on Sculptra from ultherapy treatment however, many physicians are awaiting studies, should they be done, to evaluate whether or not the Ultherapy can induce a shorter duration of benefit of the Sculptra's volume effect or if there is any change in the structure of the Sculptra from the Ultherapy energy that would make it react in an unfavorable way. There is no definitive answer to your question. Certainly, a prudent course to follow would be for the Sculptra to dissolve over two years prior to doing Ultherapy while waiting for a consensus to be reached. If studies prove their is no ill-effect then you could have the treatment possibly sooner.
