Detailed answer

Some medications can lead to skin dullness due to their side effects. These side effects may include dehydration, increased sensitivity to sunlight, or a decrease in skin cell turnover. Dehydration can make the skin appear dull and lackluster. Medications that increase sensitivity to sunlight can cause skin damage, leading to a dull complexion. Additionally, certain medications may slow down the natural process of skin cell turnover, resulting in a buildup of dead skin cells on the surface, which can contribute to a lack of radiance. If you are experiencing skin dullness after using medications, it is advised to consult with a healthcare professional for further evaluation and guidance.
