Dull skin is a common condition where the skin lacks brightness, hydration, and a healthy glow, making it appear tired, rough, or uneven. It’s often caused by a buildup of dead skin cells, poor circulation, dehydration, or a loss of essential nutrients. Factors such as aging, environmental stressors like pollution and sun exposure, and lifestyle choices like poor diet, lack of sleep, and stress can further contribute to this issue. Without proper care and treatment, dull skin can lead to premature aging, a lackluster complexion, and reduced self-confidence.
