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 properties, and can resist free radicals generated in the body due to sunlight radiation. 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 color of tomato, 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, and at the same time reduce sunburn and redness caused by sunlight.
4. foods rich in vitamin a. Such as carrots, pumpkins, spinach, kale, rape and other orange and dark green vegetables. Because the synthesis and repair of epithelial tissue of skin 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 and pricking hands, and even dry eyes.
Extended data:
In addition to 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 for bathing should not exceed 40 degrees Celsius, and it should be 32℃ ~ 40℃. Take a bath at most 1 time every day, and it should not exceed 10 minute each time. Because healthy skin is covered with a thin layer of lipid, if the lipid is damaged, the skin will lose water 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 bath lotion should be as simple as possible. People with allergic skin and patients with eczema and dermatitis, it is best to choose low-sensitivity and non-irritating skin cleaning products-the ——pH value is best close to the normal physiological value of epidermis, the ingredients are simple, and there are no spices and preservatives, and 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 skin 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 scratching. 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, you can use an emollient to prevent it, or wet it with cold water.
6. Develop the habit of drinking water regularly and quantitatively and pay attention to a balanced diet, which will help the skin to keep healthy and beautiful.
