How to prevent sun exposure is the most effective?
A, to prevent sun exposure A is to avoid, that is, to prevent sun exposure. The strongest sunshine every day is from 10 to 4 pm, during which outdoor activities can be avoided as much as possible.
B, hard sunscreen B is block, which is hard sunscreen. If you must go out, you can take an umbrella, wear a hat, or choose to walk in the shade. Its sunscreen ability far exceeds that of any sunscreen on the market, which can largely avoid damage to the skin. When purchasing sun protection clothes or umbrellas in summer, you should choose products with UPF (ultraviolet transmittance) greater than 40 and UVA (the most harmful part of ultraviolet rays) transmittance less than 5%. Only by reaching this standard can we effectively prevent ultraviolet rays!
C. Apply sunscreen C or cream, that is, apply sunscreen. If we say that some parts of our bodies must be exposed, such as climbing mountains and swimming in the sea, we should apply sunscreen to make up for it, which seems to have played a role in picking up the missing pieces, but many people often regard it as the first choice.
D, diet sunscreen is diet, that is, food diet. Eating more vegetables containing vitamin C, vitamin E, polyphenols and carotenoids, such as tomatoes, pumpkins, carrots, broccoli, purple potatoes and purple cabbage, can improve the skin's resistance to sun damage by 30%.
Tips for sun protection in summer
Tip 1: Apply sunscreen.
I believe many people will do this. Summer is coming, and they have prepared several bottles of full sun protection. But it will only be used in exposed parts of the body. Actually, this is very wrong. Sunscreen should be applied as much as possible, not only on the exposed parts of the skin, but also on sunny days and cloudy days.
Tip 2: Apply hydrating mask.
It is recommended to apply a hydrating mask 2-3 times a week. After all, the air is dry in summer, and human skin is easy to replenish water, so applying a hydrating mask can effectively replenish skin moisture and look more tender.
Tip 3: Choose a time to go out.
From 1 1.00 am to 15.00 pm, you are advised to travel less. At this time, the intensity of sunlight is greater, the damage to the skin is more serious, and it will be more difficult to repair. Traveling at night is the best time, not only can you feel a good night view, but mainly it is not dark yet!
Tip 4: Bring a parasol.
Maybe there are still a few people wearing sun protection clothes in real life, so I suggest you take a sunshade when you travel, but don't underestimate the power of this umbrella. Most people rely on it to avoid tanning in summer.
Sun protection tips
1. How much sunscreen should I wear at a time?
Apply sunscreen 20~30 minutes before going out. Sunscreen is as big as American almonds and as heavy as a dollar coin.
2. How often do you reapply sunscreen?
Sunscreen will be oxidized by ultraviolet rays, so it should be reapplied every 2 hours.
3, sunscreen must remove makeup?
If you are prone to acne after using sunscreen, it is best to use a mild product to remove makeup. At present, some sunscreens do not need to remove makeup. Whether it will be uninstalled depends on your facial feeling.
4. Is it necessary to choose waterproof sunscreen?
If you are a "sweaty" girl or China paper, or love swimming, you can choose waterproof and sunscreen products. It is recommended to remove makeup for waterproof and sunscreen. If it is for daily use, it is best not to be waterproof, at least you don't have to consider the problem of makeup removal (lazy circle said).
Tips on diet and sun protection
1, vegetables and fruits: tomatoes are the first kind of vegetables, and they are ripe tomatoes. Tomatoes are rich in antioxidant lycopene, and daily intake of 16mg of lycopene can reduce the risk factor of sunburn by 40%. Eating carrots at the same time will be more effective, because beta carotene can effectively block ultraviolet rays. Guava, strawberry, cherry tomato, orange and guava are recommended as antioxidant and whitening fruits with high vitamin C.
2, fish: scientific research shows that if you eat fish three times a week, it is equivalent to giving the body a natural protection similar to sunscreen, whitening the skin and protecting the skin from ultraviolet rays.
