How long does filler last?
It depends on the product and where I place it. Most hyaluronic acid fillers last somewhere between six and eighteen months. Thinner, softer fillers used for fine lines break down faster. Thicker fillers used for cheeks or jawline structure tend to last longer, partly because they sit in an area with less movement. Your own metabolism plays a role too. I tend to see patients metabolize filler faster if they are very active or have a naturally fast metabolism.
Why placement matters as much as product
The area I inject changes longevity almost as much as the product itself does. Lips move constantly, every time you talk, eat, or smile, and they have a rich blood supply, so filler placed there tends to break down faster, often in the six to nine month range. Cheeks and jawline, by contrast, sit under less muscle movement and have less blood flow, so filler placed there can hold for twelve to eighteen months or, in some patients, even longer. This is one reason I do not quote a single “filler lasts X months” answer without first knowing where we are treating.
Why consistency matters too
Thinner, lower viscosity gels like Volbella or RHA 2 are designed to move naturally with expressive areas like lips and fine lines, but that same low viscosity means your body breaks them down faster. Thicker, higher viscosity gels like Voluma or RHA 4 are built for structural support, and their density makes them more resistant to breakdown, which is part of why they last longer in the cheek and jawline.
Why your own biology plays a role
Hyaluronic acid filler is broken down by an enzyme your body naturally produces called hyaluronidase, the same enzyme I use in higher concentration to dissolve filler intentionally. Everyone produces this enzyme at a different baseline rate. Patients with a naturally fast metabolism, or who are very physically active, tend to circulate blood and lymphatic fluid more efficiently, which speeds up how quickly the filler is broken down and cleared. I have patients who exercise heavily and metabolize a full syringe in half the time of a more sedentary patient with the same product in the same area. Stress and sleep can influence this too, though less predictably than activity level.
What this means for planning your appointments
Because of all these variables, I do not recommend patients wait until filler has completely disappeared before coming back in. Volume loss tends to happen gradually, and touching up before you are back to your baseline usually means less product is needed to maintain your result than starting over from scratch. At your visit, I will give you a realistic timeline based on the specific product we used and the area we treated, rather than a generic number.
