1, the misunderstanding of skin care
1. Athlete's face: Exercise in America is not only beneficial to the inside of the body, but also to the outside world.
An active exercise may make athletes feel happy (thanks to the neurochemical endorphins that create happy emotions), but can it also make your face look better? "Of course." Madforth said, "When you exercise, blood flows faster around your body, which can make you look refreshed and radiant." In addition, exercise can help accelerate the metabolism of cells (including cells on the skin) and make us healthier. At the same time, she told me not to forget to wear sunscreen for outdoor activities. Products that can block UVA (ultraviolet A) and UVB (ultraviolet B) are the best. Madfus also reminds you to take a quick bath when you come back from running or jump off the treadmill, because sweat will clog pores and form defects on your skin.
2. What effect does smoking have on the skin?
Everyone knows that smoking is bad for the skin, but how harmful is it? Among many negative effects, Madworth put forward: "When smoking, nicotine will increase free radicals in the body, oxygen in the skin will decrease, and repeated actions will wrinkle the lips."
Free radical is a highly active chemical ion, which can harm cells and make the body produce more metalloproteinases, which can decompose collagen. Because collagen is a kind of fibrin, it connects the tissues that support the skin and keeps the skin tight and elastic. The decomposition of collagen will make the skin droop and wrinkle prematurely.
Madworth said that in the final analysis, "smoking is harmful to health." The bad news is not just for smokers. Secondhand smoke can also cause harm.
3. What you eat is what you eat: Can diet improve your skin?
Now many dermatologists don't think sugar is a symbol of sweetness. It has become the chief culprit of many other health problems, and it is incompatible with beauty. Bergman said: "Besides inducing acne, sugar is also related to skin aging." In the process of saccharification, sugar molecules combine with protein such as collagen, which makes the effect of protein worse than before and accelerates the appearance of skin aging. Her suggestion is to replace sugary snacks with vegetables and fruits rich in antioxidants. "Antioxidants are like free radical cleaners."
Madoff said. They can break down free radicals, so as not to harm more cells. Flavonoids are common pigments in plants and can be found in citrus, green tea, ginkgo biloba and wine.
Bergman added: As long as you add some blueberries to your cereal every morning, it will be very helpful. If you have to smoke or sunbathe (both of which she opposes), "it is more important for you to add more antioxidants to your food."
4. Water is the source of youth: Is it just a rumor to replenish water and moisturize again?
Eight glasses of water a day has always been the golden rule of health. But when metal marching pots and snakeskin woven bags have occupied a place in the fashion circle, is moisturizing still good for the skin?
Bergman said, not necessarily. The amount of drinking water has little to do with tender skin, but whether the skin has the ability to keep moisture is more important. This means that you need to eat the right type of oil in your diet.
Of course, Madworth said, "You must drink enough water" to keep your body moist and functioning normally. But drinking green tea and other drinks containing antioxidants is more effective for improving skin and reducing free radical damage.
5. Oil supplement: external use or internal use?
Some people with dry skin like to put oil on their bodies, while others think it is best to take oily capsules or diet pills. The answer is: grasp with both hands. Madfus said that dry skin comes from a weak skin barrier, which causes the body to lose too much water. To moisturize the skin, it is necessary to strengthen the barrier. Both methods can be achieved, but she prefers oral nutrition to prevent more potential skin problems.
"Applying oil directly to the skin," Madworth said, "may clog pores and lead to acne outbreaks." She also advises people to eat omega-3 fish oil or flaxseed oil in their daily diet, or eat more foods rich in omega-3, such as salmon and flaxseed oil. Bergman added that studies have shown that for people with eczema, rosacea and acne, taking more omega-3 can reduce inflammation and skin redness.
She also mentioned that linolenic acid is an essential omega-6 fatty acid, which is especially helpful for improving dry skin. Linolenic acid only exists in oils such as grape seeds and sunflower seeds, and is not synthesized automatically by the human body, but it can be obtained through diet or skin care products.
6. Nutritional supplements: Can vitamins and herbal formulas improve the skin?
Scientists have always doubted the effectiveness of nutritional formulas. But dermatologists say that some products may help to slow down skin damage. For anti-aging, Bergman recommended vitamins C and E, lycopene (contained in tomatoes) and lutein (usually contained in spinach and cabbage). "Nothing can remove the wrinkles you have formed," she explained. "They can only reduce wrinkles."
Madfus said that diet is the best way to increase skin nutrition. "If you have a normal and healthy diet, your skin should be good." She suggested eating more foods containing beta-carotene and vitamins A and B.
7. Beautiful Feast: Can Fruit Mask Replace Dermatologists?
Abandoning expensive beauty salons and replacing them with cheap food such as homemade juice is very attractive at first glance. But can your skin enjoy this fruit feast like your mouth?
Madoff said it depends on what kind of fruit it is. "Many acids, such as citric acid," she said, "can promote the natural exfoliation of epidermis and help relieve wrinkles and acne." But she warned that it is very important to choose ingredients that will not cause skin reactions or clog pores.
Bergman suggested that other natural foods, such as avocados, can help moisturize dry skin by adding oil and strengthening the skin barrier. But don't expect blueberry puree to bring any miracle. "Antioxidants don't play much role in the body." Bergman said.
8. Tea bags and cucumbers: Beauty value is better than afternoon tea and sandwiches?
Cucumber slices are the symbol of global family skin care. But can this old trick really cheer up our increasingly tired eyes?
"Cucumber can diminish inflammation and reduce swelling," Bergman said. She explained that low temperature also helps to reduce blood flow in local areas, so it is "definitely effective". Moist chamomile tea bags also contain anti-inflammatory ingredients.
In order to reduce skin redness, Bergman suggested using wet and cold black tea bags. Caffeine in tea helps to constrict blood vessels and relieve congestion.
9. Removing deep dirt: Is homemade scrub better?
A good scrub can remove dead skin cells from the body. But do all scrub have the same effect? Madfus says there's no reason why an expensive scrub would be more useful. Any paste with particles can remove dead skin due to its simple mechanical friction.
But Bergman warned consumers to be careful about the products they choose, some of which may do more harm than good. She suggests avoiding some homemade remedies, such as using rough walnuts or sugar: walnuts are "a little too big to hurt the skin." Sugar can be combined with protein such as collagen to accelerate aging.
10. Beauty sense: A well-rested body equals a radiant face?
The cliche of "beauty sleep" always makes sense, but wearing tights and curling irons will greatly reduce the effect of beauty sleep. "In fact, the effect is very different." Madoff said. When you sleep, your body has a good time to renew cells. If you don't close your eyes long enough, your body won't have enough opportunities to create new skin and other cells. Too little sleep also increases cortisol, a hormone produced by the adrenal gland under stress. Cortisol "causes fat cells to release sugar into your blood." Bergman said, "That's why people have weight problems under pressure." As a result, "more sugar accelerates aging." She said. So is the skin. It destroys the function of collagen and reduces the elasticity of skin.
2, the method of skin care
1: Drink plenty of water, at least 8 glasses of water every day. Besides drinking water, don't forget to eat more fruits.
2. Try to avoid the wind and the sun. Minimize outdoor activities.
3: Don't wash your face with overheated water. Be sure to replenish water with lotion after washing your face.
4. Choose moisturizing products with high moisturizing effect to directly help the skin retain moisture.
5. Use a mask with moisturizing effect to SOS dry dehydrated skin.
6: It will be effective to spray mineral water or moisturizing liquid when you feel dry skin. Especially in air-conditioned rooms, spraying on the face can not only keep the skin moist, but also refresh the mind.
Remarks: It is best to take care of skin before 10 in the evening, because skin cells are most active from 1 1 to 2 am. At this time, it is necessary to use efficient skin care products to achieve the purpose of deep nourishing and repairing.
