Detailed answer

When you are stressed, your body releases the stress hormone cortisol, which can lead to various changes in the skin. One of the effects of cortisol is the dilation of blood vessels, resulting in poor circulation. This can cause the blood to pool under the eyes, leading to dark circles. Additionally, stress can disrupt your sleep patterns, and lack of sleep can make the skin appear dull and pale, making dark circles more prominent. Moreover, stress can also lead to water retention and inflammation, which can manifest as under-eye bags. It is important to manage stress through techniques like exercise, relaxation, and getting enough sleep to help reduce the appearance of dark circles and under-eye bags.
