Drinking coffee has an unexpected effect on the skin

New study finds "unexpected effect" of coffee on skin

With the development of large-scale investigation, there is clear research evidence to prove the effect of coffee on the prevention of diabetes and reducing the incidence of liver cancer. Honorary Professor Okashi Taro of Tokyo Pharmaceutical University, who is familiar with the function of coffee, pointed out: "according to worldwide research on coffee, it is certain that coffee has become more and more reliable in disease prevention and bringing to human health."

According to the latest research evidence, coffee also plays a certain role in preventing color spots. At first glance, coffee has nothing to do with color spots, but some experts speculate that the effect of coffee on skin is mainly due to the rich polyphenols in coffee-chlorogenic acid.

Drinking more than 2 cups of coffee a day can inhibit the formation of spots.

Professor Kazuo Kondo of Tokyo Imperial Tea Women's University Graduate School investigated and analyzed the relationship between coffee consumption and skin status in 131 non-smoking women. It was found that people who drank more than 2 cups of coffee a day had the least spots caused by ultraviolet radiation. In addition, Professor Kondo also conducted a survey on the daily diet of women in the capital circle, and found that coffee, the source of daily polyphenols, accounted for the largest proportion, about 47%.

Why can actively drinking coffee prevent stains?

Why can drinking coffee prevent spots? Zhengguang Hashi, an honorary professor at Kobe University in Japan, who studies skin aging caused by ultraviolet rays, pointed out: "there are two ways in which human skin produces melanin. One is that the keratinized cells of the epidermis give instructions to the melanocytes that make the pigment, and then make it into melanin; the other is that the melanosomes made by the pigment cells receive melanocytes from the pigment cells. Chlorogenic acid can block these two channels, which may be the reason to prevent spots. "

In addition, the causes of color spots, wrinkles, skin relaxation, etc., in addition to ultraviolet rays, reactive oxygen species and so on, women's mental pressure will also increase color spots and wrinkles. Professor Shibashi pointed out: "reactive oxygen species is the root cause of accelerating human aging." In the summer when the sun is strong, we should not only apply sunscreen and do good skin care from the outside, but also drink some coffee to increase the intake of chlorogenic acid to help resist oxidation and protect the skin from the inside.
