Under-eye bags are oftentimes hereditary. This long-term puffiness, swelling or sagginess develops over time and is usually only surgically removed.

Under-eye dark circles have two major causes: pigmentation and poor microcirculation. This condition may aggravate due to stress, dehydration, lack of sleep, and eye strain from staring at screens.

Tear bags are a small, shallow pouch that’s just below the eye but doesn’t sag. This condition can be a sign of aging, but it can happen at any age—even children.
