Think of your face as if it were divided into thirds:
Top third: forehead, brow, and upper eyelid
Middle third: lower eyelid and cheek
Lower third: lips, chin, and neck
To rejuvenate the entire face requires forehead lifting, blepharoplasty, midface lifting, a neck lift, and maybe a little laser resurfacing. Not many people relish the idea of going through such a marathon operation.
Blepharoplasty goes a long way towards restoring two of the three units noted above, while remaining much more modest in scope, risk, cost, and recovery time. If your eyes are bright and expressive, the significance of a slightly sagging neckline is greatly diminished.
Thus, many people elect to undergo blepharoplasty before or instead of full face restoration. And since the eyelids tend to age earlier than the forehead and neck, there is little reason to wait.
If the rest of your face doesn't give out until ten or twenty years after the eyelids, the only thing accomplished by delaying eyelid surgery is giving up the chance to enjoy the improvement during those two decades of relative youth and vigor.
