Filler, blepharoplasty, or mid facelift to maintain a youthful appearance? (Photo)

This area you are referring to is called the 'tear trough', and is super common as we age. I generally inject fat into this area to volumize the ligament that causes the depression there. Can do this in the office, patients absolutely love this.
I can't see the skin scrunching but assume it's crows feet (wrinkles at the corners of the eyes). This is treated with neurotoxins like botox or a browlift. Hope this is helpful :)

Based on this photo it appears that combination of lower transconjuctival blepharoplasty and fat grafting, micro and nano, of periorbital area would create nice improvement. Hope this helps.
