Options to improve upper eyelid/brow appearance 10 years after blepharoplasty & orbital rim shaving?

At least from the photos provided, the use of an appropriate HA filler would seem to be a rather quick and easy way to restore not only a more feminine fullness to under brow region, but restore the ideal upward and outward flare of the lateral third of the eyebrows (which would secondarily help to diminish the sagginess of the upper lids, as well). You would be wise to consult an experienced board certified cosmetic dermatologist injector. In experienced hands, this should take no more then about ten to fifteen minutes to achieve on-the-spot results that typically evoke an immediate "Wow!" response. Best of luck.
