Eat 11 kinds of "natural sunscreen" to prevent tanning in summer

Although the temperature in early summer is not high, the ultraviolet radiation is no weaker than that in summer. Various types of sunscreen cannot provide any fundamental whitening and sun protection effect. If you want to truly block UV damage from the inside out and prevent the production of melanin, you need to eat more of these "natural sunscreens".

1. Orange

Oranges contain a large amount of vitamin C and carotene, which can inhibit the formation of carcinogens, soften and protect blood vessels, promote blood circulation, and lower cholesterol and blood lipids.

Studies have shown that drinking three glasses of orange juice a day can increase the level of high-density lipoprotein (HDL) in the body, thereby reducing the risk of heart disease. Orange juice contains a specific chemical component, namely flavonoids and limonin, which can promote the increase of HDL and transport low-density lipoprotein (LDL) out of the body.

2. Kiwi

Kiwi fruit is a fruit with extremely high nutritional value. Its soluble solids content is 20%. It contains more than ten kinds of amino acids such as leucine, phenylalanine, isoleucine, tyrosine, valine, alanine, etc. It is rich in minerals. Every 100 grams of pulp contains 27 mg of calcium, 26 mg of phosphorus, 1.2 mg of iron. It also contains carotene and multiple vitamins.

The vitamin C content of kiwifruit is over 100 mg (per 100 grams of pulp), and some varieties are as high as over 300 mg, which is 5-10 times that of citrus and 15-30 times that of apples and other fruits. Therefore, it is known as the "king of fruits" in the world.

3. Strawberries

Strawberry is a berry that contains polyphenols, which have an inhibitory effect on tyrosinase, which promotes the production of melanin. In addition, the active oxygen generated by ultraviolet radiation damages the DNA in the cell membrane and converts lipids into lipid peroxides, which causes blood viscosity. The tyrosinase contained in berry fruits plays an important role in inhibiting the formation of lipid peroxides and preventing blood viscosity.

In addition, strawberries are more suitable for oily skin, and have the effect of removing oil and cleansing the skin. Strawberry juice can be squeezed and used as a facial beauty product. Many cleansing and nourishing facial masks now contain strawberry ingredients and are suitable for all skin types. Regular use of strawberry beauty products can make your skin fresh, smooth and avoid pigmentation.

4. Peach

Peach is a sweet and delicious fruit that many people love to eat. The rich fruit acid it contains has moisturizing effects, and can also remove dirt from the pores, prevent pigmentation, and prevent wrinkles. In addition, peaches contain a large amount of vitamins B and C, which promote blood circulation and make the facial skin healthy and rosy.

For rough skin, you can rub and massage peach slices on cleansed face and then wash it off. This method will help keep the skin smooth and tender. In addition, adding a little peach juice to the bath water and soaking is also a good way to care for the skin.

5. Cherry

Cherry is a fruit that contains a lot of iron and carotene. It is very nutritious and can replenish blood and kidney for people with weak qi and blood. Eating 200-300 grams before meals can regulate gastrointestinal function, which is very beneficial for people with poor digestive function. The rich vitamin C in cherries can moisturize and whiten the skin and effectively resist the formation of melanin. In addition, the fruit acid contained in cherries can also promote the formation of the stratum corneum.

6. Apple

Apple peel is rich in "apple polyphenols". It contains green acid, catechins, anthocyanins, etc., which have powerful antioxidant effects. Use the antioxidant effect of "apple polyphenols" to fight the harmful effects of active oxygen produced by ultraviolet rays and protect beautiful skin. In addition, it also has a certain effect on melanin production and skin whitening. Try washing the apples and eating them with the skin on!

7. Tomatoes

The rich lycopene in tomatoes not only has antioxidant effects, but also has a certain effect on pigmentation and rough skin caused by ultraviolet rays. According to research conducted by Japan's Kagome Co., Ltd., lycopene can be retained in the skin and exert its effects. It can be said to be "edible sunscreen". Heating oil can improve the absorption efficiency of lycopene, so it is recommended to add some olive oil to the cooked tomato juice or canned tomatoes.

8. Lemon

Lemon is rich in vitamin C, which can promote metabolism, delay aging, whiten and lighten spots, shrink pores, soften the stratum corneum, has a strong care effect on the skin, and can also enhance the skin's resistance to the sun.
