What Would Be Best for a Young Patient with a Gaunt Face and Tear Trough Deformity?

Fillers  are a great substance to use to treate deflated tissues of the face. I have used in the cheeks, in lowr malar regions, the jawline, the ansolabial folds, marionette lines,  the eyebrows, the temples,etc..

Although many fillers could be used, in your particular situations I believe poly l lactic acid (Sculptra) would be my choice as it is an excellent filler for large area facial contouring.  Because it makes you make your own collagen it also is long lasting (2 years).  You should seek someone experienced in its use.
