How Long Does Botox+filler Will Last Around Frown Lines?

Botox (made by Allergan) and Dysport (made by Medicis) (both Botulinum toxin type A) last about 3 months, although some variations occurs from patient to patient.  The onset of Dysport is typically a little quicker (12-24 hours) that Botox (about 5 days), but both last about the same length of time.  The most common filler agents are hyularonic acid agents, such as Restylane (Medicis) and Juvederm (Allergan), although there are a great many others.  These agents commonly last about 6 months, although some may have adequate results up to a year (and some less than 6 months).    Filler agents are more commonly used for the lines around the mouth and the lips, but are sometimes necessary for the lines in the forehead and between the eyebrows.  Hope this helps.

Thank you for your question. The frown lines between the brows can be address two different ways:
1) Botox or Dysport can be used to soften the deepening of the frown lines when making a frown expression. The treatment may even soften the lines that are present at rest.  The effects typically last 3-4 months depending on the dose.
2) Restylane or Juvederm can be used to soften the frown lines that are present even when you don't make an expression.  This can last for a year or more when used in conjuction with Botox.
For someone who has concerns with both the static lines (without expression) and the dynamic lines (with expression), then using both products would work well together.
I often find that patients who return after a Botox or Dysport treatment in the frown areas complaining it didn't work, is due to the confusion between the static and dynamic frown lines. They continue to see the static lines even though the dynamic lines have softened considerably.

Both Dysport and Botox can last up to four months. Some people maintain their lack of wrinkling after the Dysport or botox wears off by retraining themselves not to make the grimace.  Fillers are usually not used in the frown lines, but hyaluronic acid fillers such as Restylane and Juvederm are safer to use in this location than Radiesse, Sculptra or Fat.  Restylane and Juvederm can last a year but fillers in this area must be cautiously used. They are used more often in the cheeks for volume, and the smile folds, and on and off label in the lips. Duration is often 10 to 14 months although patients can see it starting to wear off gradually, sooner.
