Is there any way to help restore my face to the way it was?

Thank you for your question about cheek augmentation.Options:Healthy dietExerciseRegain some weight back to your baselineInjectable filler such as Voluma to the cheeks for cheek augmentationTo be sure, see two or more experienced, board-certified Plastic Surgeons, occuloplastic surgeons or facial ENT plastic surgeons in your area for a complete evaluation to make sure you are a good candidate and that it is safe for you to have treatment.I hope this helps.

There are many ways with fillers and lasers that can do very well for this type of condition. I have treated patients with HIV lipoatrophy for 9 years and have amazing results. I suggest seeking an expert in facial contouring who uses all the types of fillers and has experience in cosmetics and lasers.  Best, Dr. Emer.

Chemical peels, microdermabrasion, and other non-invasive resurfacing treatments will help improve the color and texture of your complexion. Additionally, a corrective at-home skincare regimen will complement the resurfacing through deep cleansing, hydration, toning, and exfoliation. Nevertheless, these treatments will not restore volume and definition to your face. For that, I would recommend starting with injections of Voluma, an AHA filler designed to volumize hollow cheeks. I might also recommend Utherapy to soften the appearance of brow lines, nasolabial folds, marionette lines, and skin laxity around the jawline and chin. However, without photos and an in-office examination, these are only possible approaches to your problem. You need to see a licensed specialist in medical aesthetics, and he or she will develop a non-surgical treatment plan and skincare regimen that best meets your needs.  

Without a picture we must assume that you lost fat and perhsps muscle in your face. If you have noemal fat disribution in other parts of your body, fat transfer to the deficient areas might work. Also, other facial fillers could be considered.
