Radiesse® grants immediate and long-lasting results, with the average patient seeing their results last for over a year and sometimes even as much as two years. Because the results aren’t permanent, however, maintenance treatments will be required in order for patients to maintain optimal results. The active calcium-based ingredient in Radiesse® works to stimulate new collagen production to give it longer-lasting results than hyaluronic acid-based fillers like Juvéderm® and Restylane®. Curious about the longevity of Radiesse® vs. Juvéderm®? Radiesse® reviews show that this filler lasts 12-18 months or longer, while Juvéderm® typically lasts six to nine months. You will see immediate results of your Radiesse® filler, but full results of your treatment appear within about a week.
