Lower eyelid bags develop from a variety of factors. These factors may come with age, but may also be present from a younger age. From an anatomic perspective, eye bags may be from the following: Excess fat around the eye itself, protruding forward and creating bulges; Too little fat in the area beneath or under the eye bag itself, creating a hollow or sunken area and creates a shadow; Insufficient bone volume of the cheeks; Loose and wrinkled skin and Excess pigment or blood vessels in the skin and tissue.
