Alcohol consumption can have negative effects on the skin. It can lead to dehydration, which can make the skin appear dull and dry. Alcohol can also dilate the blood vessels near the skin's surface, causing redness and flushing. Over time, excessive alcohol consumption can contribute to premature aging, including wrinkles and loss of elasticity in the skin. It can also exacerbate skin conditions such as rosacea and acne. Staying hydrated and limiting alcohol intake can help minimize these effects on the skin.
