Losing subcutaneous fat is part of the aging process. Facial fillers are an injectable cosmetic treatment that helps to restore lost facial volume, smooth lines and enhance facial contours. Facial fillers can be made out of several different ingredients, each of which has special properties. For example, Poly-L-lactic acid helps to stimulate collagen production, while hyaluronic acid helps to hold moisture to keep skin plump. Many patients have questions about whether Ultherapy and fillers can work together. There have been stories about Ultherapy dissolving fillers and thus canceling out the treatment. These stories should be regarded with skepticism since there have been no scientific studies measuring the effect of Ultherapy Scottsdale on fillers. Nevertheless, if you are interested in both Ultherapy and fillers, there is a case to be made for having the Ultherapy first and then delaying the fillers for a few months. The reason is that if Ultherapy is effective, you may not require the same filler treatment that you anticipated.
