Maintenance treatments help you look younger and rejuvenated consistently. How often you need repeat appointments depends on the type of injectable and how well your tissues respond. Patients who choose to have a liquid facelift need a specialized treatment plan to keep their youthful results. Typically, dermal fillers are necessary every nine to 12 months or when you notice your results fading. Botox treatments are needed every four to six months as the muscles regain strength.
