1, tips for women's summer health care
1, there is strong ultraviolet light in cool wind: ultraviolet light will not generate heat. For example, when people climb a mountain, the higher they climb, the cooler the mountain wind will be, but the stronger the ultraviolet rays are at this time. For every rise of 1000 m, the ultraviolet ray is enhanced by 10%. The same is true in the sea. The sea breeze makes you feel cool, but at this time, ultraviolet rays often reach a very strong level. In addition, 90% of ultraviolet rays can penetrate clouds, and clouds are not the best killer of ultraviolet rays.
2. T-shirt has better sunscreen effect: a simple T-shirt is better than any sunscreen, and a small straw hat is also very useful. If you wear sunscreen with an SPF of 30, you don't have to worry about how your whitening plan will be affected.
3. More protection is needed after tanning: skin thickening and melanin production are manifestations of skin self-protection, but melanin can only partially absorb ultraviolet B, but has no function of absorbing ultraviolet A, so it is essential to create an isolation barrier between sunlight and skin when outdoors. It is wrong to think that once the skin is tanned, it doesn't need sun protection.
4. Avoid red and black food: According to nutritionists, if you use red food and then bask in the sun, your skin will get tanned more easily. Therefore, we should try to avoid eating red food such as papaya before sun exposure. In addition, black food such as soy sauce, black vinegar, coffee and so on. Containing more melanin, it is easy to cause pigmentation of the skin, so it is easy to make the skin black.
5, vitamin C supplementation: As we all know, the whitening effect of vitamin C is more obvious. Therefore, if you want to whiten, a certain degree of internal adjustment is also essential. When eating at ordinary times, try to eat foods rich in vitamin C, such as tomatoes, cucumbers, potatoes, carrots, spinach, milk, seafood and so on. Keep skin healthy, beautiful and naturally whitening.
Sunscreen is very important for women in summer. If you don't want to get dark, you'd better act quickly. Let's take a look at what misunderstandings should be paid attention to when choosing sunscreen.
2. The misunderstanding of choosing sunscreen
Myth 1: The thicker the sunscreen, the better. Many girls like to apply thick sunscreen before going out, thinking that they can escape the chase of the sun. But this is not the case. There are two reasons: first, sunscreen products are composed of chemicals, which will irritate the skin and even cause skin allergies under the action of high temperature and human sweat. Second, too many sunscreen products will block pores and sweat glands, which is not conducive to the secretion of sweat and sebaceous glands and is easy to induce skin infections and cysts.
Myth 2: The higher the SPF, the better, and the more expensive the sunscreen. When choosing a sunscreen product, we should pay special attention to its sunscreen performance, that is, its ability to filter and block ultraviolet rays (SPF and PA). Sunscreens are generally marked with SPF and PA indices. Some people think that as long as you buy expensive sunscreen products with high SPF, you will be foolproof. Actually this is a misunderstanding. Because the higher the sun protection index, the more chemical components it contains, the greater the stimulation to the skin, and the more opportunities for allergic reactions. The correct way is to choose sunscreen products according to your own skin characteristics and sunscreen needs. Before buying sunscreen, you should try it on the inside of your wrist. If the skin becomes red, swollen, painful and itchy within 10 minutes, it means that you are allergic to this product and should use other products. When buying sunscreen products, you should first consider what your sunscreen needs are. If you only use it on your way to and from work, you can choose one with a SPF 15. If you want to do outdoor activities or travel for a long time, it is recommended to use sunscreen products around SPF20; If you want to exercise in the hot sun, or go swimming at the seaside, you should choose a sunscreen with SPF30 or so and waterproof function.
Myth 3: As long as you apply sunscreen, everything will be fine. Many people think that as long as they wear sunscreen, they can go out safely and never get sunburned or sunburned. Actually, it is not. The wisest choice is to avoid going out when the sun is strongest. Even if you go out, you should do double protection: apply sunscreen and hold a parasol.
Myth 4: Only applying sunscreen does not "remove makeup". The principle of sunscreen is to form a protective film on the skin, thus refracting the ultraviolet rays emitted by the skin. Physical sunscreen and sunscreen are also oxidized with the increase of sunscreen application time, and the sunscreen effect will weaken when it is absorbed to a certain extent, and it will be gone after a long time. The disadvantage of chemical sunscreen is that if it is used for a long time, it will cause dependence and damage to skin cells and skin structure, especially cosmetics containing more lead and mercury, so the first task is to clean it in time. At the same time, when you go out in summer, a lot of dust will inevitably be adsorbed on your face, so when you come back from the outdoors, the first task is to remove makeup and completely wash off the sunscreen on your face. Ordinary facial cleanser with strong oil removal ability can thoroughly clean chemical or physical sunscreen without facial cleanser with makeup removal function. Within a few minutes after washing your face, as long as you feel that your face is not tight or greasy, it is a sign that your face is clean. If you feel that the facial keratin is too thick, such as blackheads on your nose, you can choose exfoliating facial cleanser. Of course, because many sunscreens are waterproof, it is better to use professional cleansing oil to clean them.
Summary: When summer comes, the sunshine becomes more intense, and sun protection is what everyone should do every day. I hope the above contents can help you avoid some misunderstandings in sun protection.
3. Precautions for applying sunscreen
1, when to wear sunscreen is also a key thing. It should be noted that sunscreen must be applied half an hour before going out, and then supplemented before going out. In this case, the human skin can be effectively absorbed, and then the sunscreen can give full play to the sunscreen effect.
2. What is the dosage of sunscreen? In terms of dosage, at least 1-2ml is needed at a time to achieve the best isolation effect.
3. The time when the sun is most harmful to the skin must be avoided, from 10 to 2 pm. At the same time, there should be some items that can help protect against the sun, such as some sun umbrellas, hats, long-sleeved clothes, sunglasses and so on.
4. There is also a sunscreen. Many female friends directly apply layers of sunscreen on their faces, but you should know that in the end, what you add to your skin is not sunscreen benefits, but fat particles! The best thing is that you can gently wipe off some sweat and grease with paper first, and then use sunscreen powder to make up your makeup.
The above are the skills of using sunscreen. If you want to use sunscreen to protect your skin, it is very important to know and master the correct use of sunscreen. There are many kinds of sunscreens on the market. Choosing according to your own needs will be of great help to skin sunscreen.
