How can diet make skin more beautiful and healthier?

The physiological structure of skin determines the characteristics of skin. The nutrient transport of epidermis comes from dermis, which can only be supplied to cells in basal layer through basement membrane, while stratum corneum can only be nourished by fat secreted by sebaceous glands. But due to environmental factors, the oil film formed by these fats is not enough to protect the skin surface. In order to make the epidermis look moist, you need to use cosmetics such as moisturizing cream. Choose milk for oily skin, cream for dry skin and cream for mixed skin to replenish moisture and oil film in the stratum corneum and make the skin surface more shiny. The nutrition of dermis comes from blood in blood vessels. No matter how cosmetics manufacturers and beauty salons promote it, the ingredients of cosmetics can't enter the dermis, so beauty is eaten. Beauty is that all female friends who eat it know the importance of vitamins A, B, C and E to the skin, and all kinds of cosmetics and health products can't do without it, because these nutrients can't be synthesized by the human body and must be taken from food, and these vitamins are essential to participate in the physiological process of the skin. In fact, there are minerals such as calcium, iron, zinc, selenium and phosphorus. These are all micronutrients, which need to be ingested every day, not in excess. Just be careful not to destroy vitamins when cooking. Some female friends, in the case of adequate nutrition, take vitamins for a long time, but it is more serious. I didn't know it was a drug spot until I got to the hospital. It was caused by vitamin poisoning.
