Dark circles or correction of bags underneath lower eyelids can be caused by several factors and each one has different ways for correction. For instance dark circles can be from any of the following factors:
1) Hyperpigmentation of the skin (which can be caused by certain medications) and even worsened during pregnancy
2) Age-related decent of midface of cheek fat which results in a larger deficiency of volume at the lid-cheek junction
3) Prolapse or herniation of the eyelid fat pockets (bulging fat pockets)
4) Thin skin allowing the underlying muscle and blood vessels to show
5) Underlying allergies or rosacea You should have a complete examination by either a dermatologist or a plastic surgeon to first evaluate the etiology of the “dark circles.”
