The duration of a filler will depend on numerous factors, including the specific filler used, the treatment area, and the rate at which your body metabolizes the filler. Some HA fillers last about 6 months, while others can extend up to 1 year or even longer. In general, areas of the face that have more movement, such as around the lips, will not see results that last quite as long. Other fillers/collagen stimulators, such as Sculptra, work by triggering the body to produce more collagen. While the results take time to develop, they can last up to 2 years for some patients. I encourage you to schedule a consultation with an experienced, board-certified injector who can assess you in person and customize your treatments to your precise needs and goals.
