Fat/fillers to jaw line = heavy lower face?

To answer your question, if filler injections are performed properly, they should not contribute to heaviness in the lower face.  The injection specialist should use a proper technique that would create an overall "lifting" effect of the face and simply fill in lines and folds (nasolabial folds, etc.) without creating unwanted volume.  It is important to find a board certified plastic surgeon to consult with about the results you wish to accomplish, as sometimes patients will benefit more from a facelift surgery than from filler injections.Best of luck!

This is an excellent question. yes, too much fat grafting can be too much of a good thing. There can be fat atrophy in the lower face, and in the right patient conservative fat grafting can absolutely create a more youthful profile. Look  at the before ad after images on the website of a plastic surgeon to get an idea of their aesthetic ideal.

While fillers or fat injections can be particularly helpful in the area behind the chin (Marionette creases, pre-jowl creases), if the presence of jowl formation is significant, a facelift provides an important component to the rejuvenation process.  The key with any kind of filler is moderation and good injection techniques.  An additional option includes chin implantation which augments the bone in the same region to the side of the chin.  The latter may not be for every person, but it is something worth asking about.  Additionally, regarding facelifts, there are different techniques other than the "deep plane" lift that can be effective. 

Thank you for your question.To best help you, a physical or picture evaluation is required in order to determine which procedures and techniques would be best for your case and that way come out with a good review.

You are exactly right.  A youthful face is egg or triangular shaped and smaller at the bottom.  When fillers are used to get rid of lines and folds in the lower face, they do, indeed, make the face look more boxy and, to some extent, less youthful.  However, their usefulness is in disguising the early signs of aging in someone who is not ready for or does not desire surgical correction of these problems.  They have essentially allowed us to do things for a few years to keep you looking relatively youthful before you need surgery.  Overall, 60% of the facelifts I do our repeats.  Most of the first facelifts in these patients were done relatively early before the days of significant use of fillers.  Now that we have fillers available, I do not know how many people will come back for a second facelift, or, if they do, when they will do so.  Fillers also appear to be increasing the time between facelifts.
