Will the skin turn black if you drink coffee?

It is worth noting that no research has shown that the melanin in coffee deposits under human skin and that the main component of coffee beans contains caffeine, which stimulates the central nervous system, heart and respiratory system. Appropriate amount of caffeine can also reduce muscle fatigue and promote digestive juice secretion. Because it promotes kidney function, it is diuretic and helps the body to expel excess sodium ions from the body. Caffeine accelerates metabolism, promotes digestion and improves constipation. From the point of view of these functions, it can also help improve the roughness of the skin.

It is wrong to say that the skin will blacken when drinking coffee. Many MM stay up late after drinking coffee, resulting in long-term lack of sleep and disorder of skin metabolism. We all know that lack of sleep will cause panda eyes, and staying up late for a long time will also make the skin dim and lose luster, so drinking coffee will darken the skin, and it is incorrect to say that drinking coffee is bad for the skin. On the contrary, drinking the right amount of coffee can speed up the metabolism and help the excretion of toxins in the body.
