are correct in stating that there is a dynamic versus static appearance for the
face. It appears that your malar fat pad
which constitutes the cheek volume has declined. Your upper cheek is flat and begins to create
the naso-labial fold that frames the mouth.
You can have what is known as a “Midface Lift” where the malar fat pad
is raised and suspended via small incisions in the scalp. If you are not ready for this surgery, you
can use structural fat grafting to add your own fat into the cheek area or use
fillers such as Voluma. The fillers will
provide correction for a limited period of time.
Your best option at this point is a hyaluronic acid filler such as Belotero or Restylane. You notice it more when you smile because the muscles are animating and your cheeks get raised exacerbating the appearance of the depression under your eyes (tear trough). At 29, you would do best with a filler to add volume to this area and give you a smoother lid/cheek transition. Find a skilled injector in your area and you will likely be very happy with the results.
Your problem is unfortunately not unique. You have what is referred to as a tear trough which causes the bags under your eyes and exascerbates the wrinkling of your lower eyelids.
A combination of fillers - Juvederm, Restylane, etc - and well placed Botox can help minimize both of these problems, and is a great first step for many of my younger patients with these problems.
The key with these services is finding the right injector. There is no substitute for an artistic and experienced injector. It is important that the botulinum toxin service does not freeze the forehead or cause unwanted recruitment lines. You can read about my patented microdroplet method on my website. For the under eye area, there is no question that Restylane is the best treatment option for many. Again experience is the key to these services. You have to find the right injector.
