Book AppointmentWhen I talk to patients considering dermal fillers, one of the first questions I hear is how long the results will last. It is a fair question, since different fillers behave very differently in the body.
Most fillers are designed to be temporary. Hyaluronic acid fillers like Juvederm and Restylane break down gradually as the body’s own hyaluronidase enzyme metabolizes them, typically over 6 to 12 months depending on the product, the treatment area, and the patient’s metabolism.
How Different Fillers Break Down
Not all fillers dissolve at the same rate:
- Hyaluronic acid fillers (Juvederm, Restylane): generally last 6 to 12 months
- Calcium hydroxylapatite (Radiesse): generally lasts up to 18 months and also stimulates some collagen production
- Poly-L-lactic acid (Sculptra): works by stimulating collagen over time, with effects that can last up to 2 years
- PMMA (Bellafill): can last 5 years or more
- Silicone: considered permanent and does not dissolve on its own
Permanent fillers carry different risk considerations than temporary ones, since complications like migration or granulomas cannot simply be reversed with an enzyme and may require surgical removal.
Speeding Up Dissolution With Hyaluronidase
For patients who are unhappy with their results, or in the rare case of a complication, hyaluronic acid fillers can be dissolved faster using hyaluronidase, an enzyme that specifically breaks down HA. This is one of the reasons HA fillers are considered a safer, more flexible starting point for people new to fillers. Learn more about hyaluronidase treatment.
Is It Right for You?
Choosing a filler is a personal decision that should factor in how long you want results to last, your budget for touch-ups, and your comfort with a treatment that is reversible versus one that is not. A consultation with a board-certified dermatologist is the best way to match the right filler to your goals. Learn more about dermal filler treatment options.
FAQs
How long does it take for fillers to dissolve?
Most hyaluronic acid fillers dissolve gradually over 6 to 12 months. Longer-lasting options like Sculptra or Radiesse can last up to 18 months to 2 years, while permanent fillers like silicone do not dissolve on their own.
Can I speed up how fast my filler dissolves?
Yes. Hyaluronidase injections can break down hyaluronic acid filler if you want faster correction or are experiencing a complication. This should only be done by an experienced injector.
What factors affect how quickly filler dissolves?
The type of filler, the treatment area, and individual metabolism all play a role. Areas with more movement, like around the mouth, may show faster changes than more static areas like the cheeks.
Are there risks before a filler fully dissolves?
Mild swelling, redness, and bruising are common in the days after injection and usually resolve on their own. More serious complications are rare but possible, which is why choosing an experienced, board-certified injector matters.
