41, female - best procedure for hollowness under eyes & midface? (Photo)

This may not be the best photo to evaluate your condition but appears that lower blepharoplasty and periorbital fat grafting would achieve desired improvement. Good luck.

I think the best place to start for someone in their early 40s is a little bit of filler through the tear trough and what is called the nasojugal fold. This is easy to do, it gives an instant great result, and the results can last for well over a year. Subsequent treatments can last even longer. Fat grafting is also an option but I think that if the only thing you want is that area, then fillers is the easiest least expensive best option. You can also see if you like it and if you do not, there are products then can reverse the filler. Best of luck! Dr. Boschert Renaissance Plastic Surgery.
