The longevity of dermal fillers can range from six months to over a year, depending on the type of filler used and the individual's metabolism. Some fillers can last up to 2 years. For example, some Juvederm fillers can last from 6 to 12 months, calcium hydroxylapatite results can last about 18 to 24 months, and Juvéderm Voluma XC up to 2 years. Regular follow-up treatments can help maintain the results.
