When do fillers begin to wear off? Gradually over the course of estimated duration, or gradually AFTER the estimated duration?

Thank you for your question.Longevity of filler is dependent on multiple factors.  In my experience, fillers tend to gradually wear off over the 9-12 month period.  Usually this is not rendering you "back to baseline," but requires a touch up to keep the results you are trying to achieve. To be sure, see two
or more board-certified providers in your area for a complete evaluation to
make sure you are a good candidate and that it is safe for you to have
treatment.

I hope this helps.

You ask a good question.
Fillers reduce at different rates depending on their composition and the rate
at which your body breaks them down. With the example you provided, JUVÉDERM Ultra Plus, you can expect a sustained volume
for up to 9 to 12 months. This means that it may begin to gradually diminish so
that the full effects will have worn off at some point between 9 and 12 months,
which brings you back to your baseline. When receiving cosmetic injectables,
always choose a certified, skilled injector for optimal results.

Fillers gradually disappear and last longer both based on product and anatomic location injected.  Restylane typically lasts 6 months or more and Juvederm typically lasts 9 months or more.  Botox lasts approximately four months.  Best, Dr. Green

Typically, dermal fillers our gradually broken down over time.  The longevity of the product depends on the individual rate in which your own body breaks down the product and the location of the product.  If a product is anticipated to last 9 months or so it will begin wearing off during this time.

Good question. This really depends of the type of filler. If it is a non collagen stimulating filler, such as HA filler, the body immediately causes swelling of the filler with moving water into the filler. There is some minimal inflammatory response too, which creates a small amount of collagen, even in these products. Gradually the body breaks the HA down. Everyone has a different rate of break down. The estimated durations are based on how long the effect is noticeable, so breakdown starts much earlier. For collagen stimulating fillers, the body's first response is to cause increased volume by creating collagen around the filler. Eventually the body will breakdown the filler (Sculptra, Radiesse) and the effect of the volume is reduced. In the case of Bellafill, the body is unable to break down the PMMA, and the effects are permanent. The more movement in an area, the shorter the duration and the faster the breakdown of the product.Please see blog for more details.
