Why does the skin get tanned?

Why does the skin get tanned? In the hot summer, ultraviolet rays are much stronger than usual, and no matter how white girls are, they can't escape the fate of being tanned. I believe everyone is curious, why does the sun turn black? I'll tell you why the skin gets tanned.

Why is the skin tanned 1? First of all, ultraviolet radiation will darken the skin.

Ultraviolet light is one of the main causes of skin blackening. Long-term exposure to ultraviolet rays is the formation of melanin, which not only darkens the skin, but also causes pigmentation.

Solution: Do a good job of sun protection in daily travel. Whether it is sunny or rainy, you must wear sunscreen as long as you travel. Even if it is cloudy, there will be ultraviolet rays, which will also do harm to your skin.

Second, the skin lacks water.

Without water, the skin will turn black. When hydrating the body, it is equivalent to hydrating the skin, so drinking more water at ordinary times can also make the skin white. If the hydration is not in place, the skin will not only turn black, but also lose its luster, and its self-repair and anti-radiation immunity will be reduced, so the skin will turn black.

Solution: replenish enough water to the skin every day, and use hydrating skin care products such as toner and lotion reasonably and correctly. It is very important to make your skin tender, fair and moist.

Third, lack of sleep

Staying up late is not a good thing, not only bad for the skin, but also harmful to the body! Sister paper opportunities that often stay up late will not only get worse and turn black, but also accelerate aging. At night, the blood circulation of the skin is accelerated, which promotes metabolism and the skin will repair itself. Lack of sleep, slow metabolism, skin will naturally not get better.

Solution: Adjust sleep quality, go to bed early and get up early, and don't exceed 1 1 at night. This can not only whiten the skin, but also improve the quality of the skin, health and immunity of the body and skin.

Fourth, take a bath often.

Frequent bathing and rubbing, if the intensity is not appropriate, will lead to skin blackening, and hard rubbing will stimulate skin cells, leading to the deposition of dark brown pigment and light brown pigment.

Sun protection knowledge

Five, the stratum corneum aging

There are cuticles on the face and body skin. When the stratum corneum is damaged, it will age, and the skin will become dull and darker.

Solution: You need to apply a layer of skin care products to protect the stratum corneum after taking a bath every day, which can prevent the stratum corneum from aging, better protect the skin and make the skin healthier. Healthy skin will naturally become white and tender.

It's very important to want the skin to turn black, and daily skin care is also very important. So we must pay attention to the details in our daily life. The skin will naturally get better!

Why does the skin get tanned? It is easier to get a tan when swimming.

Have you ever found that if you often go swimming outdoors or exercise at the seaside for a day, you will get a clear bronze tan? Because when we are at the seaside or swimming pool, we wear less clothes and almost expose a large area of skin, so the area irradiated by ultraviolet rays will be wider. In addition, many people think that the temperature in water and ocean is much lower than that on land, and the ultraviolet rays of the sun cannot be irradiated. Actually, water is the same as glass floor. They all have the principles of refraction and scattering, which can increase the sensitivity of skin to ultraviolet rays and make skin absorb ultraviolet rays faster.

If the skin is not tanned, choose the right swimming time.

If you are not sunburned by swimming, then you'd better choose to swim in the indoor swimming pool. If you are swimming outdoors, it is recommended to go around 5 pm, because ultraviolet rays are not so strong at this time, which can reduce the absorption of ultraviolet rays by the skin, but even at this time, it is recommended to wear a little waterproof sunscreen, which will be better.

Note: Be sure to dry your body as soon as possible after swimming to reduce the refraction of ultraviolet rays.

Why is the sun getting whiter and whiter?

A few people are surprised that they will not turn black after sunbathing, and some will become whiter and whiter. In fact, the whiter the whiter is just an illusion of everyone. The more you get sunburned, the whiter your skin is because everyone's metabolic mechanism is different. People who get sunburned and whiter will find that they sweat easily, especially when they meet the sun, which is medically called sweating white. When a person's skin is affected by sunlight, which makes the metabolism faster than others, the speed of skin melanin and keratinocytes will naturally be faster. As long as melanin is not precipitated by keratinocytes, there will be no tanning. The whiter the sun, the whiter a person is, because she can metabolize it in time, just like some people can't eat fat.

Why does the skin get tanned? 3 10 trick makes you turn white quickly!

1, clever use of soothing spray

After a day of exposure in summer, my face will be red and itchy, which is usually a prelude to tanning. Don't use moisturizing products from the beginning at night. Wash your face with mild facial cleanser to calm your skin. This step is very important. Because the skin itself is fragile after one day of exposure, direct use of whitening products will further stimulate the skin. Hydrating spray is undoubtedly the best choice. Spray your face can quickly cool down, or you can apply cucumber slices to your face, which has a calming effect.

Step 2 use skin care products as an aid

At present, no ingredient can completely whiten. Then, in the process of nursing, we should choose ingredients that can block the transmission of melanosome to keratinocytes and effectively prevent the skin from turning black, such as nicotinamide and 4MSK.

3. The essence is more effective on the face.

Wet the mask paper with distilled water or emulsion without surfactant, then drop 5- 10 drops of whitening essence, and then apply the mask paper. If the effect is obvious, you can stick a plastic wrap to bless it. For local applications, it can also make people who are suitable for frequent business trips recover quickly.

4, aging keratin should be cleaned regularly.

The renewal period of our skin is 2 1 day. If you want to whiten your skin quickly, you must increase your skin's metabolism. We can use exfoliating products regularly to speed up this process and make whitening and hydrating products better absorbed. Generally, the use cycle of exfoliating products is 7- 15 days, oily skin can be used once a week, and dry skin can be used once every half month.

After tanning, many people feel that the skin surface seems to have a second layer of skin, which is dry and dull. This is because sunlight causes the fusion of melanin and old keratin. If you want to whiten quickly, you must first remove these old horniness. It should be noted that whitening products should not be applied immediately after exfoliation, but a layer of emulsion should be applied first, paving the way for the new "exposed" keratin to moisturize, slowing down the stimulation of whitening products, and then nursing normally in the future.

5. Replenish water to strengthen cell nutrition

Make-up water can strengthen the repair of skin keratinocytes, accelerate the absorption of subsequent nutrients, such as vitamins, amino acids, minerals, antioxidants and other ingredients, and make the new stratum corneum more beautiful visually.

6, should keep the sun.

It is best not to wear makeup after the skin is damaged by the sun exposure. On the one hand, it can prevent the pigmentation from aggravating, on the other hand, it can prevent the skin from being more seriously hurt in the process of makeup removal. Try to reduce going out, use straw hats, umbrellas, sunglasses, etc. And use some sunscreen. Sensitive people's skin is more exposed to the sun. Before symptoms appear after long-term sun exposure, you can take aspirin 1g first, then take 0.5g every 4 hours for 2 days, and drink plenty of water to avoid skin redness, blackening and burning pain.

7. Drink plenty of water

In fact, the simplest and most convenient whitening method is to drink more water. Many people may think that drinking water has little effect on whitening. However, if you want to whiten, you should pay attention to the supplement of water. Proper hydration of cells can take away the old wastes in the body. Usually ultraviolet radiation can make melanin in the bottom layer of skin proliferate, and it can be quickly removed by supplementing water to promote metabolism. This method is more practical than using skin care products to replenish moisture from the epidermis.

8. Milk whitening

Prepare a small glass of fresh milk. In summer, you can also put fresh milk in the refrigerator first, which will be more comfortable. Fill the cotton pad with fresh milk, apply it to your face for about fifteen minutes, take it off and wash the milk on your face with clear water. Long-term persistence can make the skin white and even.

9. Some foods are experts in post-sun repair.

Also pay attention to eat more whitening foods, such as tomatoes, coix seed, pomegranate bitter gourd, strawberries, tomatoes, soybeans, sardines and so on. These foods have strong antioxidant properties, and at the same time can supplement the substances needed for skin repair after sun exposure, such as vitamin C, plant isoflavones, unsaturated fatty acids and so on.

10, whitening repair should be "taboo"

Eat less acidic foods such as sweets and meat, so as not to affect the metabolism of vitamin B group and cause acne and blackheads. In addition, you must use sunscreen when drinking lemonade, so that you won't be exposed to the sun, otherwise it may be darker.
