Collagen is a natural protein, which exists in the skin, tendons and other connective tissues of all vertebrates and many invertebrates. About 70% of the dermis in human skin is collagen.
When I was young, there was a lot of collagen, but with the increase of age, collagen would be gradually lost, which led to the rupture of collagen peptide bonds and elastic nets that supported the skin, and its spiral network structure was destroyed immediately, and the skin tissue was oxidized, shrunk and collapsed, and the skin would be dry, wrinkled, slack and inelastic. Therefore, it is necessary for women to supplement collagen to delay aging.

Application of collagen:
1, skin care
As an effective cosmetic raw material, small molecular collagen can moisturize skin and give it a smooth feeling, so it is called "bone in bone, skin in skin, meat in meat", which can be said to be a powerful backing of dermis, and its effect on skin is self-evident.
Collagen added to skin care cosmetics has good compatibility with other raw materials and good synergistic effect, and can effectively repair damaged skin. After oral administration of pure collagen 1 month, it is generally reflected that the skin feels delicate, smooth, fine wrinkles are well stretched, and the skin color is whitened.
2. Blood vessels
Collagen interweaves with elastin and polysaccharide protein in connective tissue to form a network structure, which can maintain the elasticity of blood vessel wall and prevent blood vessel rupture and embolism. Collagen also has the function of blood coagulation. After collagen interacts with platelets, it causes a series of subsequent processes related to blood aggregation, which can quickly coagulate blood.
3. Bones
70-80% of the organic matter in bones is collagen. When bones are formed, sufficient collagen fibers must be synthesized to form the framework of bones. Therefore, some people call collagen the bone in bones.
Collagen can combine calcium with bone cells, and prevent osteoporosis caused by calcium loss. If you only supplement calcium, it is not easy to improve the phenomenon of osteoporosis, because calcium can not be preserved in bones, and eating more calcium will also be lost, mainly because the amount of collagen has been reduced. Therefore, in order to keep the bone, it can be taken from food or supplemented by collagen health food.
4. Eyes
Cornea is one of the important structures in the eye, and the collagen fibers contained in it are arranged regularly, which not only allows light to pass through, but also makes the cornea transparent because of the special arrangement of collagen fibers.
Because collagen is the main component of cornea, protein, the contact lens made of collagen is very suitable for human body, that is, it has high physical fitness, and its water retention is better than that of contact lenses made of other materials.
