Bags under the eyes—mild swelling or puffiness under the eyes—often start appearing in individuals in their 40s or 50s, though some develop them in their 20s. Excessive use of electronic devices, staying up late, and an imbalanced diet, among other unhealthy habits, can lead to the early onset of under-eye bags. Although they do not harm vision or pose health risks, under-eye bags can make eyes appear swollen and tired and make a person look older.
As individuals age, the tissues around the eyes weaken, including some of the muscles that support the eyelids. The supportive fatty tissue may migrate into the lower eyelids, causing them to appear swollen. Fluid accumulation beneath the eyes can also result in mild swelling, sagging or loosening of the skin, and dark circles.
