Botox and Filler Together or Just One? And if So, Which?

The best treatment option really depends on your individual circumstances and goals. In general, an appropriate skincare regimen, resurfacing procedures such as peels and lasers, and finally Botox or Dysport injections can address fine wrinkles under the eyes. For undereye bags, I typically use Restylane in the lower eye areas and then Perlane or Radiesse to fill in the entire cheek (not just the cheekbone). This makes the undereye bags less noticeable. I would recommend a consult with an experienced physician. When you are in good hands, the chances of any negative side affects are greatly minimized. I hope this helps, and good luck! 

Depending on what your aesthetic goals are, you probably have your answer. If it's volumizing, then any dermal filler injected well, will help improve that volume loss. It it's volumizing AND wrinkles you're trying to help avoid, then yes, doing both at the same time help for longer term correction of the area.
