You look fairly young, but unfortunately, dark circles or deep tear-troughs can be a problem at any age. They can be due to any or all of 5 factors:1. Shadowing from congenital or acquired (via bone and fat resorption as we age) volume deficits2. Rubbing the eyes, for example, if one has allergic conjunctivitis or atopic or contact dermatitis, which can cause the skin to hyperpigment3. Thin skin, usually from aging and/or sun exposure, which allows the tiny blood vessels to show through4. A defective orbital septum, which allows fat to protrude and therefore creates a shadow5. Excessive stremgth of the medial fibers, nearest the eye, of the periorbital muscle, such that when one smiles, a shadow is created from the bunched-up fibers.Only an in-person evaluation can determine which factors are operative in your case, but each can be treated successfully. If the first cause is part or all of the problem, Restylane or Beletero may help. The second and third factors can be treated with topical retinoids and antinflammatories, and addressing any allergies or irritants. The fourth factor is best treated through plastic surgery, although I have seen patients who do not wish to have surgery improve with dermal fillers. The last factor can be mediated with just 2 to 4 units of Botox. Based upon your photo only, the first and possibly the fifth factors may be contributing to your problem. I would be delighted to see you inconsultation so that the causes and relevant treatment(s) can be discussed.All the best, Dr. Clark
