Dark circles under the eyes are a common cosmetic concern caused by aging, genetics, fatigue, allergies, dehydration, and lifestyle factors like stress, smoking, or excessive alcohol consumption.

They appear as bluish, brown, or black shadows beneath the eyes, often making a person look tired or older. While not usually a sign of a medical issue, they can affect confidence and appearance.

Home remedies include getting sufficient sleep, staying hydrated, using cold compresses, and applying cucumber slices or tea bags. Cosmetic options such as under-eye concealers can offer quick fixes. For more lasting solutions, medical treatments like laser therapy, chemical peels, fillers, and PRP injections are available.

Prevention includes using sunscreen, managing stress, avoiding smoking, and maintaining a healthy sleep routine. Although dark circles aren't usually harmful, persistent or one-sided darkening may require medical attention. Consulting a dermatologist can help identify the cause and determine the most suitable treatment.
