1. There are many reasons for the loss of collagen, such as the increase of age, the damage of ultraviolet rays, the deterioration of the environment, the irregular work and rest, and the long-term lack of moisture in the skin. In addition to irresistible aging factors, a great reason for collagen loss is the damage of ultraviolet rays, because ultraviolet rays can activate melanin and eat collagen.

2. More than 80% of the collagen loss caused by ultraviolet irradiation is due to the destruction of ultraviolet rays, which can activate melanin in the skin, penetrate the cortex and destroy collagen. Great pressure of life, improper work and rest, great pressure of life and improper work and rest will all lead to stagnation of detoxification metabolism in the body and make the body? Secretion disorder, toxin accumulation, collagen destruction. Adequate rest and a mild and cheerful mood are necessary conditions to reduce the loss of collagen.

3. Electromagnetic radiation from computers and mobile phones, automobile exhaust, air pollution and other environmental pollution elements. Which long-term contact with the skin will increase your figure? Free radicals destroy collagen, making skin dry and dark yellow, wrinkles appear early, long spots and so on.

4. The loss of collagen will first lead to the loss of skin moisture, and wrinkles will appear when the skin is dry and dry. The skin will also lose its elasticity, become slack and droop, and the pores will increase. In addition, after collagen is swallowed by melanin, if the activated melanin cannot be discharged in time, it will also bring about problems such as pigmentation, uneven skin color or dullness.

Extended data 1, more than 90% of collagen loss is due to ultraviolet rays, so sun protection can prevent collagen loss. In addition, supplementing foods containing collagen can also slow down its loss. In some foods containing colloid, beef tendon and pig's trotters are rich in collagen.

2. Usually, eggs (the absorption rate of boiled eggs is above 99%), bean products (high-quality protein), lean pork, livestock and poultry meat and other protein contents are high. The absorption rate of protein is related to trace elements and vitamins. For example, increasing the intake of vitamin C, calcium, iron and other elements while ingesting protein can improve the absorption and utilization rate of protein.
