Injection of collagen to whiten and remove wrinkles in one step What effects does collagen have on the skin

Inject collagen to whiten and remove wrinkles in one step. Which is better, collagen or pig's trotters is indeed a controversial topic. Collagen is a high-molecular protein. Filament collagen fibers keep the skin strong and elastic. It exists in human skin, bones best penis pump , teeth, tendons and other parts, and its main physiological function is to serve as a binding substance for connective tissue.
1. Skin function: Protect and have appropriate elasticity:
The underlying epidermis chastity sissy , which occupies most of the structure, is the dermis layer, with a thickness of about 2 millimeters. It can be divided into three layers, namely, the papillary layer, the underlying papillary layer and the reticular layer. Most of them are composed of proteins. This part of the protein is composed of collagen and elastin, and the rest are nerves, capillaries gay masturbation , sweat glands and sebaceous glands, lymph vessels and hair roots.
70% of the skin composition is composed of collagen. The skin is like a large sleeve that tightly wraps around the body, with a considerable surface area. When the human limbs move, the collagen in the skin functions, giving the skin a protective function and appropriate elasticity and hardness.
2. The bones are hard and elastic, so as not to be loose and fragile:
Bones contain calcium. When the calcium contained in teeth is lost, it will cause tooth lesions clitoral vibrator , which can easily cause tooth decay and periodontal disease. When bone calcium is lost, it will lead to osteoporosis. Collagen allows calcium to combine with bone cells without loss.
When collagen in bones is lost, the amount of calcium in bones will also decrease. If only calcium intake is increased at this time, it will not be easy to improve this osteoporosis phenomenon. Because calcium cannot be retained in bones, eating more calcium will also be lost, mainly because the amount of collagen has been reduced. Therefore, to preserve the bones, you can consume them from food or supplement them with collagen health foods.
The ratio of collagen to elastin content in the dermis is about 45:1, while the collagen content in bones accounts for about 20%. Collagen is the main protein component in both skin and bone. If calculated based on the total protein content in bone, 80% is collagen. Because they contain collagen, bones and teeth are elastic while hard.
