Detailed answer

Not getting enough sleep affects your skin in multiple ways, causing it to appear dull. During sleep, the body goes through a process of repairing and renewing skin cells, promoting a healthy complexion. When sleep is inadequate, this process is disrupted, leading to a buildup of dead skin cells on the surface. Additionally, lack of sleep can reduce blood circulation, resulting in a decrease in oxygen and nutrients delivered to the skin. This can lead to a lackluster and tired-looking complexion. Furthermore, sleep deprivation can increase stress levels and trigger the release of stress hormones, which can negatively impact the skin's natural balance, leading to inflammation, breakouts, and a dull appearance.
