Tough to tell much from these pictures. You do seem to have a fairly deep lower eyelid. I am surprised the restylane didn't help . You may just need to have more put in. Blepharoplasty will sometimes help the darker color by stretching the skin. But you would still want to do something to fill in the hollow and fat might be a good option for you. Really need to be seen in person to figure out what would work best.

Getting rid of black eyes, wrinkles, and excess skin
Upper and lower eyelid blepharoplasty may be an option for you. Although, the procedure will not change the color of the skin, it can smooth and stretch the skin, which can result in a lighter appearance. A skin lightening cream, along with the blepharoplasty, could be considered. Seek out a board certified plastic surgeon with extensive experience in blepharoplasty surgery. Best wishes, Dr Lepore.
Getting rid of these dark eyes
As always, it is difficult to make recommendations for treatment without seeing someone in person. Of course, the photos help, but the quality and head position, make it difficult to make concrete suggestions. The first photo suggests that you may have true upper eyelid ptosis and if this is the case you would need to address this with bilateral ptosis repair, not just upper lid blepharoplasty. I would suggest you find a physician near you from the directory of asoprs.org. Good luck!
