Is 3 vials of Sculptra for my face too much at one time? Is it safe?

You would need to be examined to determine the appropriate number of Sculptra vials to use in a treatment.  I have used 3 vials in one treatment, but that would be in someone with severe loss of volume.  I generally only use one or two vials per treatment.  Because Sculptra is a stimulating agent, you get a better effect from repeated treatments rather than using more than needed in a session.  The incidence of side effects can increase with using more product as well.   

Yes, 3 vials of Sculptra can be performed at one time and is safe in SOME patients.However, Sculptra treatments are more commonly done in a series.  Placing too much Sculptra in an area can pre-dispose to inflammatory reactions and/or nodules.  Sculptra is an excellent product to add volume to certain areas of the face, but requires patience and commitment on the part of the patient to undergo the necessary amount of treatments (and vials) to get the best results.  That is, the results come in months (not days or weeks) from the initial treatment, and may require 2-5 treatments depending on the person's volume loss or hollowness.You can read more about Sculptra by clicking on the link below.I hope this helps.

My general treatment protocol with Sculptra is to inject 2 vials per treatment session.  Although 3 vials can be administered in one session, whether or not this is appropriate for you cannot be answered without a physical examination.
