The depth of skin color mainly depends on the ability of melanocytes to synthesize melanin. There are a certain number of melanocytes between the basal layer and the basal layer of human epidermis, which contain tyrosinase necessary for melanin synthesis and can promote melanin synthesis. The more melanin is produced, the darker the skin is, and on the contrary, the skin is fair.

What does dull and yellow skin eat? For this problem, experts pointed out that for skin care, everyone should take more meals needed for skin nutrition in their daily diet, such as:

Eat more carrots, pumpkins, tomatoes, spinach, lettuce, bananas, oranges and other foods. These foods are rich in vitamin A, which can prevent skin dryness, desquamation and cracking, and play a role in lubricating and strengthening the skin.

Eat more animal liver, soybeans, malt, mustard and vegetable oil. These foods contain vitamin E, which can help skin metabolism and maintain skin elasticity.

Eat more foods rich in vitamin C, such as tomatoes, kiwis, oranges, lemons, hawthorn and jujube. Vitamin C can interrupt the process of melanin production and reduce pigmentation, black spots and freckles.

Eat more skin, such as pigskin. There are a lot of collagen and elastin in the skin. Collagen is a special macromolecular protein, accounting for 85% of the protein of skin. After being absorbed by human body, it can promote skin cells to absorb and store water, and effectively prevent skin from drying and wrinkling. Elastin can enhance the elasticity and toughness of skin, make blood exuberant, provide sufficient nutrition for skin, and make skin delicate. Therefore, we should always eat pigskin, which is not only beneficial to bodybuilding, but also can delay aging.
