Dark circles under the eyes, often attributed to fatigue or screen time, can sometimes indicate underlying health issues, including liver stress. When the liver struggles to flush toxins due to poor diet, alcohol, or lack of sleep, it can manifest as dull, darker skin around the eyes. Dermatologists note that while genetics and lifestyle are common causes, liver issues might present with additional symptoms like overall dullness, puffiness, or yellowish skin tone. However, the liver is rarely the sole cause, with most cases involving a combination of factors.
