What is causing my upper eyelid to look hollow near the orbital bone? (Photos)

Genetics and weight loss can cause fat loss around eyes. Other causes include Latisse use and prior surgery. The most effective predictable treatment would be upper eyelid filler injection. I have a publication on this subject.

The appearance of the upper eyelid is affected by the contour of orbital rim snd the periorbital fat around the eye. Both of these change with age,creating a hollowing affect. If you have deep set eyes to begin with, this can become more pronounced. The are ways to soften this, by using fillers or surgical techniques. Consult a surgeon who performs orbital surgery for evaluation.

A deep upper sulcus or sunken upper eyelid is usually due to stretching or tearing of the upper eyelid lifting muscle tendon (levator aponeurosis). This causes a drooping upper eyelid but some people can compensate sufficiently by raising their eyebrows. So upper eyelid range of motion (levator function) and degree of ptosis always need to be checked while canceling the action of the brow lifting muscle. If your eyebrows were in there normal position I would bet that you would have a significant amount of upper eyelid drooping. The other reason for believing this is the case is that I cannot see the crease where the levator inserts into your upper eyelids. Before going the route of fillers or surgery for hollowness it is immensely important that you are evaluated face to face by a qualified surgeon. Treatment without an accurate diagnosis can be quite problematic. I suspect that this has been going on for more than a few weeks.I hope you realize that this format of posting questions and receiving answers lacks the face to face direct communication required for you to make an informed decision regarding your surgery.
My response to your question/post does not represent formal medical advice or constitute a doctor patient relationship. You need to consult with i.e. personally see a board certified plastic surgeon in order to receive a formal evaluation and develop a doctor patient relationship in order to know if this assessment is valid.

Thank you for your question. You have loss of volume of the upper eyelid. This can happen in patients who have naturally deep set eyes. Looking at your photos, you may be a candidate for filler to the upper lid, but an in-person consultation would be needed to confirm that.

Thank you for your question. I see this quite often with patients whom are thin. The truth is that you have lost some fat of the upper orbital region. The only way you can truly treat this is by replacing the fat in to that region. This might be a challenge with you however, because you probably have very little fat to transplant. Please see the advice of a double board-certified facial plastic surgeon to help you with this condition. Have a good day

The hollowness above your upper eyelids is hereditary. There is nothing wrong. 
A filler or fat can be injected into the area just below the orbital bone, and this will diminish the problem if you are self-conscious. The fillers can be injected with no anesthesia, but the fat would probably require some mild sedation and a liposuction of a small area to get the fat. The fat grafts can be done as an office procedure.
Thank you for our interesting question, and good luck.
