Under-eye Dark Circles. I give up?

I always have dark circles. Even as a kid. Of all the 'common factors that lead to dark circles', found across the internet and also popularly believed, none apply to me. I am never sleep deprived, always sleep at least 6 hours a day, or even more. I drink a lot of water, I am not underweight or anaemic, I do not have allergies or deficiencies. Even as a 5 year, I had them. Till very recently, I had perfect vision. Although couple of months ago, I started wearing myopic glasses for 0.5-0.5 in each eye. But I am sure it has nothing to do with my dark circles condition. I have spent a bomb visiting ophthalmologists, dermatologists, on expensive under eye creams and cosmetics. Nothing has worked. In fact, due to excessive (failed) treatments, (including home remedies), my under-eye skin has become very fragile, dry, and wrinkly. Doctors say that it might be due to 'Capillary Leakage'. I don't necessary need any more treatment, I only want to know if it is curable or should I give up?
