1, sweet potato. Sweet potato is rich in β-carotene, which is an important antioxidant, which can help the human body fight against free radicals and slow down the aging of free radicals.

2. Green tea. Green tea is a powerful skin care food, which can not only accelerate human metabolism, but also contain high concentration of catechin, which has anti-inflammatory, anti-aging and antioxidant effects, and can resist free radicals produced by sunlight in the body. Green tea also contains polyphenols, which can inhibit the activity of free radicals. Therefore, drinking tea can also prevent skin cancer.

3. tomatoes. Lycopene is an important antioxidant, and tomato is one of its best food sources. The redder the tomato color, the higher the lycopene content. Studies have found that eating tomato sauce can significantly enhance the skin's ability to protect itself from harmful ultraviolet radiation, while reducing sunburn and redness caused by sunlight.

4. foods rich in vitamin a. Such as carrots, pumpkins, spinach, cabbage, rape and other orange and dark green vegetables. Because the synthesis and repair of skin epithelial tissue can not be separated from vitamin A, if vitamin A is seriously insufficient, the resistance of skin and mucosa will be reduced, and the immune function of mucosa will also be reduced, resulting in rough skin, tingling hands and even dry eyes.

Extended data:

Besides helping to repair the skin by eating, we should also protect the skin from the following points:

1, control the bath time and water temperature. The water temperature of bathing should not exceed 40 degrees Celsius, and 32℃ ~ 40℃ is appropriate. Take a bath at most 1 time every day, and do not exceed 10 minutes each time. Because healthy skin is covered with a thin layer of lipid, if the lipid is destroyed, the skin will lose moisture and become dehydrated and dry. Washing with hot water will accelerate the loss of this layer of oil and make the skin drier.

2. Choose the right bath products. The ingredients of shower gel should be as simple as possible. People with skin allergy and patients with eczema and dermatitis, it is best to choose skin cleaning products with low sensitivity and no irritation-the ——pH value is best close to the normal physiological value of epidermis, the ingredients are simple, and there are no spices and preservatives, so the use times of cleaning products should be reduced appropriately.

3. External use of emollients after bathing. Ordinary people can apply emollients once a day after taking a bath. People with obviously dry and sensitive skin need to use emollients at least twice a day. Because emollients can not only prevent water evaporation, but also repair damaged skin, reduce the stimulation of exogenous adverse factors and relieve skin itching.

4. Avoid scratches. Scratching not only damages the skin and is prone to infection, but also repeatedly scratching for a long time will step into a vicious circle of itching and scratching. If the skin itches, it can be prevented with emollients or wet with cold water.

6. Develop the habit of drinking water regularly and quantitatively, and pay attention to a balanced diet, which will help keep your skin healthy and beautiful.
