Was Overfilled with Sculptra in Lower Face, How Can I Fix this?

Don't worry, 1.5 diluted vials of Sculptra should not leave you with a dramatic "overfilled" look like you're referring to. Continue massaging as much as possible (this is very important!) With more time for the swelling to subside and the product to settle, I expect that you'll be much happier with the results. 

At four weeks very little of the effect you see would be due to the Sculptra itself. It takes longer to show very much effect.

I have personally treated many patients, sometimes using as much as four vials at one session and never had overfill.

It seems very unlikely that you will end up with overfill with only 1 1/2 vials..

Even at this late date, massage will often help.  In your lower face it is best done if you place one finger inside your mouth and others outside and do "through and through" spreading of the area where it appears too full.

Be patient, you should be fine.
