How long do dermal fillers last?

Once filler is in, the next question is how long it will stay. The useful split is between normal fading and a change that needs a call.

How long your filler should hold

No single number holds for every filler. The person who injected you is the one to ask, and the answer depends on the product, the area treated and your own history. Leave the visit with the filler's name and the expected range on paper.

Fading that can wait, changes that cannot

Sort what you notice into two piles. Gradual fading that matches what your injector described is cosmetic and can wait for a routine appointment. A new change in a treated area that worries you is not a fading question and should not wait for the next appointment. While you are still at the clinic, ask which changes they want a same-day call about.

Fillers are not one product, so the first thing to pin down is which kind you received. If you do not know what category your filler belongs to, start with the plastic surgery society's overview of dermal fillers and match any product names you find there against what your injector tells you. It is general background, and the range your injector gave you for your product is the one to go by.

If a change worries you and you want to know how filler problems get counted, read the pooled analysis of adverse events after hyaluronic acid filler in the face. It shows how researchers collect and group reported problems, which helps with triage but says nothing about duration.

A filler record to keep

  1. Write down the exact product name and the amount used at your visit.
  2. Ask what range of time your injector expects for that product in that area, and what they would count as normal fading.
  3. Ask which early changes should send you back to the phone.
  4. File the product record with your other health records.

When fading is not the issue

How long your filler lasts is something to settle with the clinician who examined you. If you feel seriously unwell after any treatment, contact your physician or emergency services.
