For your eyes only - What causes the formation of undereye puffiness or "bags"?

Your eye rests on a cushion formed by small clusters of fat separated by walls of connective tissue, constantly in use by the eye muscles. As the skin of the eyelids is very thin and deformable, the fat can, in some cases, cause a small hernia to form, commonly called an undereye “bag”. As skin slackening accentuates with age, these “bags” tend to worsen and above all no longer diminish after resting. Genetic predisposition for this condition is frequent, explaining the presence of bags in some children and adolescents. Stress and fatigue accentuate them.
