Eating more of these foods will make the skin more vulnerable to ultraviolet rays and turn black or long spots, so you should take them in moderation.

If you really can't help it, you might as well add some foods containing vitamin E to fight aging before eating, such as pumpkin, banana, spinach, carrot, whole wheat bread, peanuts, sesame seeds and brown rice.
2, whitening vitamin foods
Peas: According to Compendium of Materia Medica, peas have the effect of "removing black and lifting noodles". Modern research has found that peas are rich in provitamin A, which can be converted into vitamin A in the body to moisturize the skin.
White radish: Chinese medicine believes that white radish can "benefit the five internal organs, make people white and clean muscles." White radish has this function because it is rich in vitamin C. Vitamin C is an antioxidant, which can inhibit melanin synthesis, prevent fat oxidation and prevent lipofuscin deposition. Therefore, eating white radish often can make the skin white and delicate.
Carrots: Carrots are called "skin food" and can moisturize the skin. In addition, carrots are rich in pectin, which can combine with mercury, thus eliminating harmful components in the human body and making the skin look more delicate and ruddy.
Asparagus: Asparagus is rich in selenium, which can resist aging, prevent and treat various diseases related to excessive oxidation of fat, and make skin white and tender.

3. The misunderstanding of sun protection in summer
Myth 1: You only need sun protection when the sun is strong in summer.
Truth: ultraviolet rays can't be treated like sunlight. Ultraviolet rays in sunlight exist in sunny days, cloudy days, cloudy days or all the year round. Only rainstorm clouds can block some ultraviolet rays in clouds. Therefore, whether it is sunny or cloudy, you need to do a good job of sun protection.
Myth 2: The higher the SPF value of sunscreen, the better.
Truth: The higher the SPF, the more sunscreen you add, and the greater the irritation to the skin. Suggestion: If you go to work normally, you can choose SPF 15 and PA+ sunscreen products. For outdoor sports, you should choose SPF25~SPF35 and PA++ sunscreen products. If you go swimming at the seaside, you need to choose SPF35~SPF50 and PA+++ sunscreen products.
Myth 3: Apply sunscreen only a few minutes before going out.
Truth: The effective ingredients in sunscreen must penetrate into the stratum corneum to play a protective role. It is recommended to apply sunscreen 20 minutes before going out. In the dosage used, at least 1~2 ml should be applied every time to achieve the best sunscreen effect.
Myth 4: You only need to apply sunscreen once a day.
Truth: After sunscreen is applied to exposed parts for several hours, the sunscreen effect will gradually weaken due to sweat dilution and other reasons. It is recommended to clean and reapply sunscreen every 2 hours to ensure the continuation of sunscreen effect.
Myth 5: Unused sunscreen will continue to be used this year.
Truth: I didn't run out of sunscreen last year and will continue to use it this year. Actually, this is not right. The shelf life of sunscreen is generally two years, but it will deteriorate or agglomerate after long-term use. It is recommended not to use it again.
Myth 6: You can get a tan without sun protection.
Truth: After sun exposure, the skin is brown, indicating that the skin has entered a state of self-protection. The thickening of the stratum corneum and the production of melanin are actually manifestations of skin self-protection. But melanin can only absorb some ultraviolet rays. Therefore, when you go outdoors, whether you are tanned or not, the isolation barrier between the sun and the skin is still essential.
4. How to repair after sun exposure?
1, you should not wash your face immediately after exposure.
After going home in the sun and looking in the mirror, I can't help but want to remove all the facial cleanser when I see the red and oily face. This method is not advisable. As the saying goes, "haste makes waste", the newly sunburned skin is very fragile and needs a good rest. It is not appropriate to use cleansing products directly, otherwise it will only increase the burden on the skin. First of all, we should refrigerate or spray physiological saline in the refrigerator, and then gently pat the face a few times to cool and replenish water to the skin.
2. Avoid alkaline facial cleanser.
After sufficient hydration, clean your face with a mild facial cleanser marked mild and suitable for sensitive skin. Generally, the PH value of facial skin is acidic, so facial cleanser with the same pH value will not irritate the skin. Alkaline facial cleanser is prohibited at this time.
3. Avoid using whitening products after cleansing.
To reduce the complicated skin care procedures after cleansing, just apply a thin layer of cream or essence. Never use whitening products. Cosmetics or skin care products with whitening effect contain fluorescent agents or heavy metals such as lead. Healthy skin is prone to allergies after application, and it is a disaster to apply it to fragile skin after sun exposure.
