Does coffee make your skin black?

Since I entered the coffee industry, I have been drinking coffee, an average of about five cups a day, two in the morning and three in the afternoon. The effects of coffee on me are as follows:

First, drinking coffee makes me feel better. It's summer. I've never taken a nap. From getting up at 7 o'clock in the morning to going to bed at 1 o'clock in the evening, I don't feel very tired or sleepy.

Second, coffee made me lose weight. In three weeks, my weight dropped from 148 to 138. As for some details of my testing coffee to lose weight, I will write an article later to explain this problem.

Today, a friend also asked me about coffee weight loss, and asked me how I managed to lose 10 jin in three weeks. I told her about my way to lose weight, but she told me that drinking coffee would blacken the skin.

But so far, no study has shown that there is an absolute relationship between melanin in coffee and "melanin" in the skin. At least foreign friends drink coffee as frequently as Chinese people drink tea, and I don't think any skin has blackened. But my friend pointed out to me that African skin is very black.

We all know that caffeine can speed up metabolism, promote digestion, improve constipation, accelerate the discharge of waste cutin, dilute dark circles under the eyes caused by poor circulation, and help relieve rough and dull skin.

When it comes to caffeine that accelerates metabolism, it is said that coffee accelerates calorie burning, thus eliminating subcutaneous fat and restoring skin tightness; another is antioxidation. Drinking coffee regularly can keep skin cells full of vitality and prevent cell oxidation. The role of anti-aging skin should not be underestimated.

Finally, it is important to mention that the reason why your skin darkens is that you may often stay up late and refresh yourself with coffee, but it is not coffee that blackens you. You know, lack of sleep is an important killer of beauty. Pay more attention to rest!

In addition, although drinking coffee will not discolor the skin, but often do not gargle after drinking coffee, will make the teeth yellow, this is true.
