Nasolabial folds are anatomical grooves from the upper outer part of the nose on both sides to the corners of the mouth on both sides, formed by the interface of two sets of muscles with different directions of movement. It is more obvious at the age of 30, and more obvious after the age of 35. Almost no one is spared, and it is one of the manifestations of human aging. Nasolabial fold deepening daily diet to pay attention to which points? 1, moderate drinking water: the human tissue fluid contains 72% water, the adult body water content of 58% -67%. When the body water is reduced, there will be dry skin, sebaceous gland secretion is reduced, so that the skin loses elasticity, and even wrinkles. In order to ensure the intake of water, the daily water intake of young girls should be about 1200 milliliters. 2, often eat vitamin-rich foods: vitamins for the prevention of skin aging, keep the skin delicate and moisturized plays an important role. Japanese scholars found that vitamin E has an important role in skin anti-aging. Because vitamin E can destroy the chemical activity of free radicals, thereby inhibiting aging. Vitamin E also prevents the role of lipofuscin deposits in the skin. Scientists have found that the production of lipofuscin is related to lipid peroxide. Foods that are high in vitamin E include cabbage, sunflower oil and canola oil. Vitamin A, B2 is also indispensable for smooth and moisturized skin. 3, eat more food containing iron: skin glossy red, need to supply sufficient blood. Iron is one of the main components of hemoglobin in the blood, so we should eat more iron-rich foods. Such as animal liver, egg yolk, kelp, seaweed and so on. 4, increase the intake of collagen-rich and elastin-rich foods: collagen can make the cells become plump, so that the skin is full, wrinkles are reduced; elastin can make the human skin elasticity enhancement, so that the skin is smooth and elastic. Foods rich in collagen and elastin are pig’s feet, animal tendons and pig skin. 5, pay attention to the intake of alkaline food: daily life eaten fish, meat, poultry, eggs, grains and cereals are physiologically acidic. Weight acidic food will make body fluids and blood lactic acid, uric acid content increases. When organic acids can not be discharged from the body in a timely manner, it will erode the sensitive epidermal cells, so that the skin loses its fineness and elasticity. In order to neutralize the acidic components of the body, so should eat some physiological alkaline food, such as apples, pears, citrus and vegetables. Nasolabial folds are a body surface mark of the human face, everyone will have, the depth of individual differences and different, will gradually deepen with age, generally at the age of 25 years old that is the beginning of the trend of deepening, and thereafter with the sagging of the facial tissues and the gradual aggravation. Nasolabial fold is a shallow groove from both sides of the nose to the corner of the mouth, the upper end of the inner upper, then outward to the lower, and then down between the cheeks and lips, so commonly known as the lip and face groove. Children and young people only smile when this groove is obvious, facial aging this groove is also very obvious.
