How long before you see complete results of fillers?

The final results from fillers depends on which fillers you use.  If you use typical Hyaluronic Acid fillers (Restylane, Juvederm, Voluma, Silk, Perlane) then the results are fairly immediate.  You may have some swelling, depending on the area injected, so it's safe to say that most of the time, your final results should be fairly close at about 2 weeks.If you use a filler like Sculptra, the final results take much longer, and multiple treatments sessions are typically necessary.  It's probably fair to say less changes are likely after about 2 months, since it relies on the body to stimulate collagen growth.  

Most fillers show the results immediately but the swelling goes down by 2 weeks and you can determine then if touch ups or more is needed for optimal correction.  I would suggest a formal consultation with a facial rejuvenation expert.  Best, Dr. Emer.

Impossible to answer. Depends on amount injected, areas injected, etc....................................
