It sounds as if you underwent a facelift. For whatever reason, you were unhappy with your results.
There are several possible explanations, many elucidated by my excellent colleagues below (expectations too high, sun damaged skin loses its elasticity, possible additional laxity). You should definitely mention to your doctor your dissatisfaction and see if there is any additional tightening that is reasonable to do without causing distortion to anatomic structures.
You might also want to consider if there are areas of hollowness such as around the mouth (nasolabial folds, marionette lines, lips, cheeks, cheekbones, undereye areas) that could benefit from augmentation with your own tissue, especially if you have had previous eyelid surgery. In our practice we use Livefill (autologous tissue; fascial fat grafts).
If tightening has been done on the side of the face but not in the center (midface), a cheeklift may be an option, especially if you had had previous lower eyelid surgery in the past.
It is also possible that the sun damaged areas could be resurfaced with a conservative CO2 laser resurfacing, both to reduce surface actinic changes from the sun, as well as to give additional tightening.
We have found that results with radiofrequency tightening devices (Refirme, Thermage) for this problem were temporary and disappointing. The internal laser offers nothing in my opinion to improve the results from most patients with your issue that should not have already have been done during your primary surgery.
I hope this helps, and good luck!
