There are many valid arguments for each type of approach to rejuvenating the eyes in lower lid Blepharoplasty. You are young and it is clear that the herniated fat that your lower eyelids exhibit is genetic in origin. You are definitely a candidate for filler in this area but, you are also a fantastic candidate for a conservative transconjunctival Blepharoplasty of the lower lids. If you have dermal filler placed in the lower lids, you will need to have the procedure repeated every 7-9 months to maintain your appearance.
In your case, a transconjunctival Blepharoplasty is extremely safe and when performed appropriately, will give you results that are superior to dermal fillers of the eyes and will last for years. At your age, and based on your photos, you will likely need little if any manipulation of the lower lid skin following fat removal or fat repositioning, which really decreases the incidence of postoperative lower lid Blepharoplasty complications. A good and thorough consultation with a surgeon experienced in both dermal fillers and Blepharoplasty will be your best bet.
