Over the years we have used many different fillers, hyaluronic acids such as Retylane and Captique, collagens such as Evolence and calcium hydroxyappetites such as Radiesse. Some are no longer produced and some carry unacceptable risks to our patients. Ultimately, with the improved technology, we now have fillers that are low risk and long lasting at a reasonable cost. Most importantly is the safety of these products. We still see patients that come to us with results, from other offices, they are not pleased with and these are long lasting and not easily correctable.
