Orbital Fat Loss - What Can Be Done? I'm 49, my Eyes Look Much Older. (photo)

Looking at your photos, it seems that your upper eyelids are somewhat droopy [eyelid ptosis]. Furthermore, I think that you are subconsciously elevating your eyebrows to compensate for this.

Raising your eyelids [ptosis repair] will definitely help your upper eyelids become less hollow. But you should be aware that your subconscious drive to raise your eyelids may go away and unmask a mild droopy eyebrow.

I would recommend consultation with an Oculoplastics surgeon [or a Facial Plastic surgeon or General Plastic surgeon that has extensive experience with eyelid ptosis repair].

You can find an ASOPRS trained Oculoplastics surgeon near you. The link is provided below.

The pictures do show a orbital fat loss and  very hollow upper lids. From the pictures is also apparent that there some ptosis present.  Repairing the ptosis will reduce the aperture of the  eyelid opening and help from raising the eyebrows to compensate for the ptosis. Best to seek out an oculoplastic surgeon well versed in ptosis repair and a possible small amount of fat grafting to the upper lids. 

You do have hollowing around the eyes from loss of fat tissue support.  A fat transfer or filler (done with a very experienced injector who is comfortable working in this area) is a good solution.

Before you proceed get an evaluation for the droopy upper eyelids that come from weakening of the upper eyelid "lifting" muscle, (called "ptosis") to see if you need a tightening procedure.  That will also help make you look less hollow.

Good luck.  I think your objectives are possible.
