Exercise is not only beneficial to the inside of the body, but also helpful to the outside world.

An active exercise may make athletes feel happy (thanks to the neurochemical endorphins that produce happy emotions). "When you exercise, blood flows faster around your body, which can make you look refreshed." In addition, exercise can help accelerate the metabolism of cells (including cells on the skin) and make us healthier. Don't forget to apply sunscreen for outdoor activities. Products that can block UVA (ultraviolet A) and UVB (ultraviolet B) are the best. When you come back from running or jump off the treadmill, remember to take a bath quickly, because sweat will clog pores and form defects on your skin.

2. What effect does smoking have on the skin?

Among many negative effects, nicotine will increase free radicals in the body, reduce oxygen in the skin, and make lips wrinkle due to repeated actions.

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.

In the final analysis, "smoking is harmful to health", and the bad news is not only aimed at smokers. Secondhand smoke can also cause harm.

3. You are what you eat;

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. In addition to 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. Replace sugary snacks with vegetables and fruits rich in antioxidants. 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.

4. Water is the source of youth;

Eight glasses of water a day has always been the golden rule of health. 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, "you must drink enough water" to ensure the body's humidity and good operation, but drinking drinks containing antioxidants, such as green tea, is more effective in improving skin and reducing free radical damage.

5. Oil replenishment:

For 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. Dry skin comes from the weak skin barrier, which leads to excessive water loss. To moisturize the skin, it is necessary to strengthen the barrier, which can be achieved by the above two methods to prevent more potential skin problems.

6. Nutritional supplements:

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). They can't get rid of the wrinkles you have formed, they can only reduce them. Diet is the best way to increase skin nutrition. If you have a normal and healthy diet, your skin should be good. It is recommended to eat more foods containing vitamins A and B.

7. A 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?

That depends on what kind of fruit it is. Various acids such as citric acid can promote the natural exfoliation of epidermis and help to relieve wrinkles and acne, but it is very important to choose ingredients that will not cause skin reactions or clog pores.

Other natural foods, such as avocado, can help moisturize dry skin by adding oil and strengthening skin barrier, but we can't expect mashed blueberry sauce to bring any miracle.

8. Tea bags and cucumbers:

Cucumber slices are the symbol of global family skin care. But can this old trick really cheer up our increasingly tired eyes?

Cucumber can reduce inflammation and swelling, and low temperature also helps to reduce blood flow to local areas, so it is definitely effective. Moist chamomile tea bags also contain anti-inflammatory ingredients.

In order to reduce skin redness, it is recommended to use wet and cold black tea bags. Caffeine in tea helps to constrict blood vessels and relieve congestion.

9. Remove deep dirt:

Self-made scrub is better? A good scrub can remove dead skin cells from the body. But do all scrub have the same effect? There is no reason why expensive scrub will be more useful. Any paste with particles can remove dead skin due to its simple mechanical friction.

Warn consumers that they need to choose products carefully, and some products may do more harm than good. It is suggested to avoid some homemade therapies, such as using rough walnuts or sugar: walnuts are "a little big and hurt the skin." Sugar can be combined with protein such as collagen to accelerate aging.

10. Beauty sleep:

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. 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 the blood. This is why people have weight problems under pressure. Therefore, more sugar will accelerate aging. So is the skin. It destroys the function of collagen and reduces the elasticity of skin.
