Several factors can contribute to an aged appearance of the lower eyelid -- descent of the cheek fat, prolapse of the fat around the eye, excess skin, etc. As the fat of the cheek descends it can leave the bony rim of the eye socket more apparent through the relatively thin skin of the lower eyelid, and cause deflation and abnormal shadowing that makes you appear older or tired. In most this occurs with age but it can be genetic (the so-called "negative vector" cheek). This is correctable in a number of ways, including with a surgery called a lower blepharoplasty. Through an incision just below the eyelashes the fat of the lower eyelid & upper cheek may be mobilized and repositioned to add volume to the lower eyelid and help the dark circles fade. Though it should not be considered a permanent solution, this approach should give you a durable improvement over 15 years or more (before you start to see the same issues appear again). You can see photos of patients who had this procedure on my profile page. This procedure should not be confused with a midface lift, which is typically performed through different approaches for different cosmetic concerns. These distinctions need to be clarified with your surgeon prior to surgery to ensure that your expectations are met to the fullest of his or her ability, with the surgery that is most appropriate. As always, obtain a consultation with a Board-certified Facial Plastic Surgeon or General Plastic surgeon to get a fully-informed recommendation from a surgeon who is able to examine you.
