How Long Do Injectables Last? Maintenance Guide & Timeline

Cosmetic injectables can soften expression lines, restore lost facial volume, and enhance certain features without surgery, but knowing how long your results will last can help you plan for maintenance. Depending on the product and treatment area, injectable results may last anywhere from a few months to well over a year, with factors like metabolism, dosage, facial movement, and the specific formulation influencing each person's timeline. In Baltimore, MD, board-certified plastic surgeon Dr. Benjamin D. Schultz and our dedicated aesthetic team offer injectable treatments including Dysport®, Restylane®, and the RHA® Collection, allowing treatment to be tailored to different types of wrinkles, volume loss, and aesthetic goals. 

Whether you're considering injectables for the first time or wondering when to schedule your next appointment, keep reading for a closer look at how long injectables last, what can affect their longevity, and how often maintenance treatments may be needed. 

What affects how long injectables last? 

Two patients receiving the same injectable won't necessarily see their results fade on exactly the same schedule. Your body, treatment plan, and lifestyle can all influence longevity. Factors that may affect how long injectables last include:  

• The product and formulation used 
• The area being treated 
• The amount of product injected 
• Your metabolism 
• The strength and frequency of facial muscle movement 
• Your previous history with injectable treatments 

Because these factors vary from person to person, your experience with previous treatments can also help establish a more personalized maintenance timeline over time. 

How long does Dysport last? 

Dysport is a wrinkle relaxer that temporarily reduces the muscle activity responsible for dynamic lines, such as frown lines between the eyebrows. Most patients begin noticing an improvement within a few days, with results typically lasting around 3 – 4 months. Individual timelines may be somewhat shorter or longer, again, depending on how quickly your body metabolizes the product and how strongly the treated muscles contract. As Dysport gradually wears off, muscle movement returns, and expression lines may slowly become noticeable again, signaling that it may be time to consider another treatment. 

How long do Restylane and RHA fillers last? 

Dermal fillers generally last longer than wrinkle relaxers, although there isn't one timeline that applies to every product or treatment area. Restylane and RHA are families of hyaluronic acid (HA) fillers with different formulations designed for specific concerns, from smoothing facial wrinkles to restoring volume or enhancing facial contours. Depending on the formulation and where it is injected, results with fillers may last from several months to a year or longer. 

Areas with frequent movement may metabolize filler more quickly than less mobile areas. During your consultation, our knowledgeable injectors can recommend a specific product and discuss how long you can reasonably expect your results to last. 

How do you know when it’s time for an injectable touch-up? 

You don't necessarily need to wait until your results have disappeared before scheduling another appointment. With Dysport, you may notice that movement is gradually returning to the treated muscles and expression lines are becoming more visible again. With dermal fillers, contours may slowly lose some of their enhancement, or lines may begin to deepen as the filler is naturally broken down by the body.

 Some patients prefer to schedule maintenance while a portion of their results remains, while others wait until they notice a more significant change. We can help determine an appropriate schedule for fillers and wrinkle relaxers based on the product used and the look you want to maintain.
