How Long Does Filler Last? Hint: It’s Complicated

Back To Blog Overview

“In terms of how long something lasts, we(cosmetic physicians) need more studies to have true scientific consensus on this, but initial findings show the smaller the droplet size – or the smaller the amount put in in any one spot – the more surface area in contact with the outside body, the quicker it can go away.” – Dr. Michelle Ellern

One of the most commonly asked questions we get about a specific dermal filler is “how long does it last?” When it comes to hyaluronic acid-based fillers, the answer is always, “it depends.”

The longevity of any given dermal filler has to do with its crosslinking. Traditional fillers that have been around for a while, like Restylane and Juvederm, are generally crosslinked differently than the newer cohesive gel fillers, which include Kysse, Refyne, Defyne, and Vollure. When estimating how long a filler will last, the formulation of the actual product being used is the most influential factor in the duration of result.

G Prime of Filler is a Measure of Cross-Linking, Which Impacts Duration of Result

Older filler formulations, like Restylane or Juvederm, will typically last around 6 to 9 months, and sometimes up to 12, depending on where they’re placed. Around this time you’ll start to notice them breaking down, which means it’s time to come back in for a refresh of those products. The longest-lasting hyaluronic acid fillers are Restylane’s Refyne or Defyne can last around 18 moths, and Juvederm’s Voluma—one of the longest-lasting fillers—can be effective for up to two years.

How Long Filler Lasts Based on Where It's Injected

However, the longevity isn’t the only aspect of choosing dermal fillers that you should consider. As Dr. Ellern explains in the video, “Really when we’re choosing—not only the filler, but the technique with which it is placed—you want to do it based on how it’s going to look in your face…” This means that, although Restylane Silk is long-lasting, it doesn’t have the strength to achieve results like improving check volume, for instance.

In addition, Dr. Ellern says another key aspect of longevity is the technique used for injection. In our experience at Reflections, there may be a longevity difference when things are placed very deep, like along the cheekbone, compared to a more superficial technique. She goes on to say, “it also has to do with how much surface area the filler has in contact with the outside of your body.”

The final factor in how long fillers last comes down to your body and your metabolism. The effects of dermal filler fades because your body naturally breaks it down with an enzyme gradually. Some people are just genetically predisposed to break hyaluronic acid down more quickly than others, and people who are more active also tend to break fillers down more quickly.

At Reflections, our physician injectors don’t pick filler purely based on the length of time it will have its effect. Dr. Ellen says, “We do it based on results.” We want everyone who comes here to have beautiful results that look effortless and natural, which is why we choose fillers based on your unique concerns and goals.
