Drinking coffee is good for the skin

Our skin not only makes people feel beautiful, but also has many important functions, including protection, thermoregulation, immune response, biochemical synthesis, sensory contact (social and sexual communication). Specifically, the skin has the following functions: (1) to protect the body from bacteria and other foreign substances; (2) sensation: the skin can feel five different types of irritation (touch, pressure, heat, cold, pain); (3) heat regulation: helps control body temperature by dissipating heat and preventing dehydration; (4) waterproof: the skin acts as a waterproof barrier to prevent important nutrients from flowing out of the body. The skin has three layers of structure: epidermis, dermis and subcutaneous tissue. The epidermis is the part of the skin that we can see. it wraps around the surface of our bodies and plays a waterproof and protective role. In different skin types, the thickness of the epidermis is different. The eyelid skin is the thinnest, with a thickness of 0.5 mm, and the palms and soles of the feet are the thickest, with a thickness of 1.5 mm. The dermis includes nerve endings, blood vessels, sebaceous glands and sweat glands. In addition, it also contains collagen and elastin, which makes the skin tough and elastic. Subcutaneous tissue is a layer of fat and connective tissue that contains a large number of nerves and blood vessels. This layer is very important. It can regulate the temperature of the skin and body. The skin is one of the first body parts to show age. We don't have a magic pill to keep you young and healthy, but there are several ways to make your skin look young and healthy, make it as young as possible, and delay aging as much as possible.

(1) limit sun exposure

(2) avoid smoking

(3) eat vegetables and fruits

(4) choose the best drugs to strengthen your immune system

(5) Sleep

(6) drinking water

(7) reduce fine lines and wrinkles

(8) use good moisturizing products

(9) choose the best skin care products.

We now know a lot about the effects of food on the body's systems (including the aging process). Eating vegetables and fruits rich in anti-aging ingredients can not only prolong life, but also make people look young. Anti-aging vegetables and fruits should contain antioxidants such as vitamin C, vitamin A, vitamin B, vitamin D, vitamin E, selenium, β-carotene, lycopene, L-glutathione and tea polyphenols. The best anti-aging fruits and vegetables are citrus fruits: oranges, oranges, limes, grapefruit, bananas, strawberries, cranberries, apples, melons, peaches and apricots. Coffee has also been included recently.

High-profit beauty products are very attractive to consumers. Coffee and caffeine are now essential in our 24-hour lives, providing us with a growing need for quality of life. In addition to caffeine exposure to coffee, the beauty industry has also used its characteristics to launch new products, such as caffeine lipstick produced by Hard Candy Cosmetics, which has three flavors (Latte Lip,Cafe-o-Lip,Lipachino). Women at work only need to lick their lips for a quick pick-me-up. Caffeine is also added to sprays and facial toners, as well as hundreds of creams and moisturizers that claim to tighten the skin and improve body shape. Clarins has added caffeine to some products, claiming to stimulate fat cells to release accumulated fat and help tighten the thighs and buttocks. The main ingredient in this skin care product is caffeine, which helps us fight fat.

Caffeine has also been found to reduce the risk of skin cancer in laboratory mice. Dr. Allan Conney, a professor at the Cancer and Leukemia Research Center at Rutgers University in New Brunswick, New Jersey, USA, said studies have shown that an emollient with caffeine or a compound in another green tea can more than halve the incidence of skin cancer in hairless mice exposed to intense ultraviolet radiation. Caffeine can significantly block the effect of abnormal cell self-destruction, and this type of programmed cell suicide can prevent abnormal cell growth, Conney said. He said it was not an anti-light effect, but a biological effect. Caffeine has a selective effect and can cause abnormal cell death, but does not affect normal cells. Although hairless mice are commonly used in such studies, they are not the best skin cancer animal experiments. Many of the things that work in mice cannot be applied to humans. Therefore, the next step in studying the local effect of caffeine is to apply it to people who are prone to skin cancer, as well as to people in precancerous state and people with skin cancer.
