Does drinking too much coffee have any effects on the skin?

Generally, excessive coffee consumption may cause dry or more sensitive skin, although some individuals may experience no obvious adverse effects. If in doubt, it is advisable to consult a healthcare professional beforehand. A detailed analysis is as follows:

Coffee contains caffeine, and excessive intake can accelerate the body's water metabolism. Without timely hydration, the skin may become dry and tight due to dehydration. Over time, this could lead to a rougher stratum corneum and even worsen fine lines. Additionally, caffeine may stimulate sebaceous glands, which, in individuals with naturally oily skin, could indirectly increase the risk of clogged pores and trigger skin discomfort.

Some people have higher skin tolerance; after moderate coffee consumption, their bodies can maintain normal balance of moisture and oil, thus not experiencing noticeable skin issues. Moreover, certain components in coffee possess antioxidant properties. Within reasonable intake levels, coffee might exert mild beneficial effects on skin condition, though such benefits vary significantly among individuals.

To maintain healthy skin, limit daily coffee intake to avoid overconsumption, ensure adequate hydration to keep skin moisturized, and if persistent dryness, redness, or other discomfort occurs after drinking coffee, reduce or temporarily discontinue consumption and seek professional advice when necessary.
