Collagen is found in the human skin, bones, teeth, tendons and other parts. In terms of skin care, collagen forms a net-like supporting structure with elastic fibers in the body, providing strong support for the dermis. With age, the amount of collagen in the human body gradually decreases, causing the skin to lose elasticity, become thinner and age. Therefore, it can be said that the aging of human skin is indeed closely related to the loss of collagen. Yishengmei Collagen's unique triple helix structure can lock in 30 times the amount of moisture, keeping the skin hydrated, glossy and tender for a long time; additionally, it achieves whitening by inhibiting the process of melanin production. After entering the skin, collagen can repair broken and aged elastic fiber networks, restoring the elasticity of the skin, making it soft and full; additionally, collagen can remove free radicals from the body, providing multi-pathway anti-oxidation and slowing down skin aging. When supplementing collagen, one must choose products from reputable brands with good quality. For food, we should be more discerning when making choices. In our daily lives, we can consume more foods rich in collagen, such as pigskin, pig trotters, cowhide, beef tendon, chicken wings, fish skin, etc. Other foods like rice, noodles, milk, vegetables, fruits do not contain collagen. Foods rich in collagen also contain large amounts of fat. Eating less of these foods yields poor results, while eating more simultaneously ingests a large amount of fat, which is not good for health. The main reason is that the molecular weight of collagen in food is large, and the amount that can be absorbed and utilized by the skin is very little.
