On average, lip fillers provide results for 6 to 18 months. The length of time is linked to the type of filler that is used to enhance the lips. Most people opt for maintenance appointments every 6 to 12 months to enjoy the results continuously. When hyaluronic acid (HA) fillers are used, such as Restylane Silk and Juvederm Ultra, lip filler treatments provide natural-looking enhancements for about 6 to 12 months. Furthermore, newer fillers, such as Juvederm Volbella and Juvederm Vollure, provide improvements that can be enjoyed for 12 to 18 months. To maximize the longevity of your lip fillers, you should shield your lips from excessive sun exposure, avoid smoking, and follow the aftercare instructions provided by the specialist. If you would like to maintain the look of your fillers, the specialist will outline how frequently touch-up sessions are recommended.
