What is Best Procedure for Mild Sagging in Lower Face and Below Eyes?

hi
Considering your age, I think that the best solution is a facelift limited to this part of the face with a lower blepharoplasty
It s simple , safe with a minimal downtime 

You may be a candidate for a limited facelift without a neck lift. People with fair skin often come to our office in New York with this concern (particularly when they are thin). Since facial aging is a combination of volume loss (bone, muscle, and fat) as well as sagging of skin and deeper tissue, it is important to determine the right procedure for you. It sounds like performing a face lift (addressing the sagging skin) would create the right structure so if you need volume enhancement with fillers, the skin will be more resilient and you will probably require less volume correction. A proper consultation with a qualified doctor is recommended.
