Hi Glendale,You have asked a very good question, one that many of our patients ask us prior to Ultherapy. We actually recommend that our patients have Botox in their forehead and crow's feet area (sometimes even in their neck) a few days before having their Ulthera treatment. Studies have shown that there is improved collagen production and healing when the forehead does not move after ablative laser procedures, the same is thought to be the case with Ulthera. As for fillers, fortunately the areas that we treat with Ulthera are mostly areas that do not normally receive fillers. We prefer to use fillers after Ulthera, and avoid treating directly over filled areas. The only filler that we do treat over is Sculptra which works synergistically with Ulthera.Our physicians perform all Ulthera treatments to insure our patients of the most effective, safe, and consistant results.Be well.Dr. P
