Can drinking black coffee blacken the skin?

Excuse me, will girls drink black coffee to make the melanin on their face more obvious?

I was born with genetic freckles, can I drink black coffee?

I am very tired at work every day. I want to drink coffee to cheer me up, but I am afraid of blackening my skin. What should I do?

Drink black coffee and worry about getting black, so... Salt, no soy sauce? Whitening by drinking milk? Drink boiled water to make it transparent?

The common fallacy in the community is that "if you eat black food, your skin will turn black." In the final analysis, this is evolved from the wrong concept of "form complement" in traditional Chinese medicine-although the concept is correct, the evolutionary logic is wrong.

Traditional Chinese medicine believes that "black enters the kidney", so Polygonum multiflorum and black beans nourish kidney essence and kidney qi, which in turn causes dark hair. However, not all black things can tonify the kidney, at least soy sauce is not.

But people don't see it that way. Everyone's idea is that if you drink something black, it is easy to turn black.

Since "drink black things, it is easy to turn black", of course, there will be "pregnant women drink milk, the fetus is more likely to turn white" further inference. This inference is easy to overturn: black people in the United States also drink milk, and black couples are born black dolls. We drink boiled water every day, but we don't see transparent people--

Black is not only melanin, but also black accumulation.

The formation of melanin is basically related to the secretion of melanin granules in melanocytes. (this is not a tongue twister.)

However, "blackening" is not just a "increase in melanin granules"; for example, a dark complexion can be a manifestation of the accumulation of old cutin.

In other words, "blackening" can be melanin production or cutin accumulation. However, from either point of view, drinking coffee does not cause melanocytes to produce more melanin granules, nor does it cause cutin accumulation in the epidermis.

Conclusion:

Drink black coffee and make sure it doesn't turn black. But the lights in the coffee shop... It's hard to say...
