The longevity of a filler largely depends on the type used and individual factors. Some fillers are designed to provide longer-lasting results compared to others. Generally, HA-based fillers can last anywhere from 6 months to 2 years, depending on the specific product and how quickly your body metabolises it. On the other hand, Sculptra, a biostimulant filler, is known for its relatively long-lasting effects, often lasting up to 2 years or more. Individual experiences may vary, and factors like metabolism, lifestyle, and the area of injection can influence the duration of filler results. Always consult with a qualified clinician for personalised information on filler options and their expected durations.
