Although not all treatments for dark circles are necessarily permanent, finding a consistent routine that works for you can help to minimize their appearance.
Common causes for under-eye bags are allergies, eczema and dermatitis around the eyes, excessive scratching or rubbing of the eyes, sun exposure, aging, and fatigue.
Age and fatigue are the most common causes of puffy eyes. People naturally lose fat and collagen as they age, which can cause the blood vessels under their eyes to become more prominent.
The development of puffy eyelids or under eye hollows is also common with age, and sometimes these can cast shadows that appear to be dark circles under the eyes.
