What caused rapid loss of Juvederm filler in my lips?

Yana,

Even though we are told that Juvederm can last up to a year, the reality is this varies from patient to patient. Some folks metabolize the product much quicker than others, so what has happened with your lips does sometimes happen.

Two other factors that sometimes cause this more rapid loss of volume after injection include the depth of injection (how deep the product was placed) as well as the amount. If the Juvederm was injected too deep, it has a tendency to sometimes be absorbed more quickly than we would like. In addition, if there was not enough product used, it will look ok for a bit, but once all the swelling goes down, there will be a need to do a repeat injection. For this reason, I will often times have patients come back at a week or so after the procedure to see if we need to do any more.

In terms of cost, this varies from one provider to the next, but many will charge by the syringe, so don't be surprised if you are asked to pay for another procedure.
