Best Procedure to Remove Dark Circles and Under Eye Hollows?

Dark under-eye circles may be due to 1) relative lack of volume between a protruding lower eyelid bag and descended upper cheek fat, 2) hyperpigmentation of the skin, 3) thinned/translucent eyelid skin with visible underlying vascularity or muscle.
Surgery is really reserved for #1 and, in my hands, the best procedure is an external incision lower blepharoplasty with fat repositioning. In this procedure, fat from the bag is not fully removed but instead "moved" to fill the area of volume deficiency. At the same time, the external incision allows the skin and m of the lower muscle eyelid to be elevated to a higher position (with removal of some excess skin). This elevation also pulls up some of the descended cheek fat (raising the lid-cheek junction).

At home peels like cosmelan, enlighten and aerify along with dermarolling (MTS roller with anteage MD ampules) should be started now. There are many things you can do to treat under eye hollows and dark circles. A surgical option to remove skin and/or fat will such as lower eyelid blepharoplasty with or without fat pad repositioning will be the best long term. There are many things you can do to treat under eye hollows and dark circles without surgery. Non invasive less downtime options such as fillers (Belotero, Juvederm Volbella​), lasers (Moxi/Halo/Fraxel/CO2​), Renuvion (J-Plasma), microneedling/PRP, stem cells and microneedling RF like Fractora PiXel8 or Morpheus can all help give some improvement. Accutite can often be used or stronger lasers like erbium or co2 spot treatment can tighten the skin and give very quick improvement in wrinkles and texture. A surgical option to remove skin and/or fat might be the best solution long-term. I suggest you get a formal consultation to see what is best for you and your goals. Best, Dr. Emer.

The short and honest answer: You can't really remove dark circles. But don't get disappointed, because there are ways of treating dark circles so they become much less noticeable. But first before treating dark circles you need to know what you are treating.
1. Hollowing: some people have true under eye hollows loss of fat (atrophy) or enlargement of their eye socket over time. This can contribute to the appearance of dark circles because of shadowing effects. The best way and probably quickest way to treat hollowing is with dermal fillers. There are many different types of fillers and we can get into a longer discussion another time of what is best to use around the eyes.
2- Pseudo-hollowing: this is the hollowing that is seeing under an eyebag. This person may have loss of volume in the midface or tear trough, but this hollowing is made 10x worse with the appearance of the eyebag above it. It's like having a huge mountain beside a valley. The valley looks deeper in comparison to the large mountain. The best treatment in this scenario is lower lid blepharoplasty to remove the eyebag and reposition the fat into the valley below. This kills two birds with one stone.
3- Hyperpigmentation of the skin: some patients because of family history or ethnicity general have more pigment in the skin around their eyes. This is probably the most difficult to treat. However, there are lasers, IPL and skin creams that can help improve your tone. But don't despair. You just need someone to point you in the right direction. Consult your favourite skin care specialist or oculoplastic surgeon :)
