Summer sun protection tips

The summer heat, sun protection has become the main topic of after-dinner beauty lovers, "how to sun protection" "with what method of sun protection", etc., have become the content of people's concern. Although there are some small props, such as umbrellas, large-brimmed hats, sunglasses, small shawls, moisturizing spray, etc., can resist UV radiation on the skin, but we need to take care of the skin from the outside to the inside.

External maintenance: sun protection is just right

Sun protection factor is not "the bigger the better"

The different UV exposure determines the sunscreen skin care products we should choose under different conditions, especially to look at its SPF and PA value. If you rarely engage in outdoor activities, you can choose skin care products with SPF 10 to 15; while when engaged in outdoor sports, you should choose skin care products with SPF 20. Do not blindly choose a product with a large SPF value. The larger the SPF value, the less breathable the product is, which will hinder the normal breathing and secretion of the skin.

Apply sunscreen not "once a day"

Sunscreen skin care products can only delay the time we are sunburned, and can not guarantee the "safety" of the whole day. Therefore, don't be optimistic that if you apply sunscreen in the morning, you can relax all day. You need to reapply sunscreen every three to five hours to protect your skin.

The sun protection is not limited to "outdoor special"

Many people make applying sunscreen a "must" 15 minutes before going out, but this is a bit one-sided. Because now the skin damage is not only from the sun's ultraviolet rays, such as the common computer a family of daily contact with the computer, their own skin is very injured. So even indoors you need sun protection.

Internal conditioning: eating out of the white skin

For sun protection, only by the external maintenance is far from enough, the internal conditioning is also very important. The daily life diet, many foods can play a certain role in sun protection, whitening, anti-aging, etc.

Cooked tomatoes

Tomato is the best sunscreen food. It is rich in the antioxidant lycopene, and a daily intake of 16 mg of lycopene can reduce the risk factor of sunburn by 40%. Cooked tomatoes are more effective than raw ones. Another tip: gently peel the skin of tomatoes and apply it to the skin for 15 to 20 minutes, it will have a good whitening effect.

Drink lemon water

Lemon is unique in whitening the skin. It is rich in vitamin C, which is an important ingredient in making skin whitening products; it contains vitamins A, B1 and B2, which not only have whitening effects, but also have a lightening effect on melanin that has been formed in the skin; and the PP component within it has a strong astringent and antibacterial effect. According to research, lemon can also reduce the incidence of skin cancer, just a spoonful of lemon juice per week can reduce the incidence of skin cancer by 30%. Drinking a glass of lemon water in the morning not only can discharge toxic substances from the body, but also has a natural skin whitening effect, helping to eliminate facial freckles.

Eat more whitening fruits and vegetables

Oranges, kiwis, bell peppers, strawberries, etc., all have similar effects to lemon. Watermelon, green leafy vegetables, carrots, oats, cabbage, onions and radishes are also good for antioxidant, whitening and melanin removal. The unsaturated fats contained in nuts soften the skin from the inside out, prevent wrinkles, moisturize and make the skin look younger. But do not expect immediate results, it usually takes 30 days to make the skin improve.

Eat fewer foods rich in beta-carotene

These foods have a light-absorbing effect or cause pigmentation, such as celery, leeks, parsley, red beans, citrus, mangoes, papaya, etc., which are rich in beta-carotene. However, as long as they are not consumed in excess, they will not have a great impact on the skin.

Tips: The significance of SPF and PA of sunscreens

SPF sun protection factor, its calculation is: assuming that the intensity of ultraviolet light is unchanged, a person without any sun protection measures will turn red after 20 minutes of exposure to the skin, when using SPF15 sunscreen, said that it can be extended 15 times longer, that is, after 300 minutes before the skin will be red. PA value is the most widely used standard in Japanese products at present. The effectiveness of protection is distinguished into three levels, namely PA+, PA++, PA+++. PA+ means effective, PA++ means quite effective, and PA+++ means very effective. However, there is no international standard for certification.
