Under-eye puffiness is a very common problem that can be a cosmetic concern for many people. The skin under the eyes is very delicate and thin, which allows the veins to show through, giving a dark discoloration. As we age, the skin becomes even thinner, allowing this discoloration to become more prominent. This can be accentuated even more by age-related sagging of the skin at the same time.
It is worth going to see your primary care doctor
because there are a couple of medical problems that might make the problem worse, including chronic nasal or seasonal allergies. If there is any evidence of allergies, it is worth treating them for a while, because often clearing up the allergies will also make the skin under the eyes appear less dark and less puffy.
On the other hand, if there is no evidence of this, then your options include using makeup or skin creams to try to improve the appearance or consulting with a dermatologist
or a cosmetic surgeon
. They will be able to discuss the more invasive treatment options, which include injecting fillers, laser-based skin treatments, and surgery itself. Again, please discuss with your doctor. Good luck.
