Dark circles and puffy eyes

Q: I have very dark circles under my eyes and also from time to time suffer with very puffy eyes. What causes this and what eye products can I use that will take this away?       The experts say:  There are two reasons for dark circles under the eyes. 

Either it is pigmentation or it is a shadow created by the bulge of the fat pockets in the lower eyelid. 

The pigmentation may be derived from stagnant venous blood and poor lymphatic drainage. Fatigue, allergy and a familial trait can cause this.

Good skin moisturisation and nutrition, enough rest and good quality filtered water will usually help a lot. Getting your GP to test for allergies.

If definite ones are found they should be treated medically.  If the dark circles are because the fat in the lower eyelid bulges, then the only real treatment is to have surgery to reposition that fat.
