Detailed answer

While lack of sleep alone may not directly cause dark spots, it can contribute to the development of dark spots. When you don't get enough sleep, your skin's natural healing and rejuvenation process is disrupted, leading to poor circulation and compromised skin barrier function. This can result in increased production of melanin, the pigment responsible for dark spots. Furthermore, lack of sleep can also increase stress levels, which can trigger inflammation and further exacerbate the appearance of dark spots. Therefore, ensuring an adequate amount of quality sleep is crucial in maintaining healthy and even-toned skin.
