Photosensitive food refers to those foods that are easy to cause solar dermatitis. Generally speaking, after the light-sensitive food is digested and absorbed, the light-sensitive substances contained in it will enter the skin. If bright light is used at this time, it will react with sunlight, and then there will be redness and rash, and the exposed skin will have obvious itching, burning or stabbing pain.
Some vegetables and wild vegetables (gray vegetables and bitter vegetables) with high chlorophyll content belong to photosensitive foods. Common photosensitive foods are lemon, grey cabbage, Chinese milk vetch, Chinese cabbage, lettuce, fennel, amaranth, shepherd's purse, celery, radish leaves, spinach, wheat, coriander, safflower, rape, mustard, figs, citrus, mango, pineapple and so on. In addition, "photosensitive seafood" also includes snails, shrimps, crabs and mussels. And it also contains photosensitive substances, which should also be noted.
To have healthy and bright skin that is not easy to get sunburned, almost every dermatologist will let you eat 2-3 servings of high-dimensional C fruits every day, such as guava, kiwi fruit and strawberry.

In addition, if you want to have skin with strong defense against ultraviolet rays, you must also fully take vitamin E to prevent skin aging, vitamin A to increase skin resistance and calcium to increase skin elasticity, which can be obtained from food.
Red and orange fruits and vegetables and dark green leafy vegetables, such as mango, tomato, papaya and water spinach, all contain a lot of carotene and other phytochemicals, which help to resist oxidation and enhance skin resistance. Tomatoes, in particular, are the best sunscreen food and are rich in antioxidant lycopene. Daily intake of 16 mg lycopene can reduce the risk of sunburn by 40%. However, cooked tomatoes are better than raw tomatoes. Among them, beta carotene can effectively block ultraviolet rays.

It can also effectively prevent brown pigment from depositing in the skin and prevent brown spots and plaques on the face.
