Eye puffiness and dark circles under the eyes occur for many reasons, including genetics, allergies, stress, eye fatigue and lack of sleep, ageing as well as individual skin characteristics. Therefore, skin in this area tends to have reduced elasticity, hyperpigmentation, irritation, and allergies may occur more often.
Puffy eyes are caused by an excessive accumulation of fluids in the tissue surrounding the eye. The skin around the eyes is very thin and sensitive, which means swelling and discoloration are easily seen.
Dark circles are darker areas under the eyes, which look darker due to vessel fragility. In this case they can be broken easily, and hemoglobin leaks out into the skin, which we can see as a dark discoloration around the eye as a result. Another reason is poor circulation, which means less oxygenated blood and the result is a bluish appearance.
Puffy eyes are characterized by undereye 'bags', caused by swelling of the surrounding tissue. Dark circles are areas of hyperpigmentation under the eyes.
