Can collagen really be supplemented?
Collagen can be supplemented, because collagen has many benefits to human body, especially it can improve the elasticity of skin. Collagen is a macromolecule. If it is just an ordinary mask, there is no way to get into the skin. The correct way to supplement collagen is to insist on using a kind of food with high collagen content for a long time, such as pig's trotters and shark's fin, because these foods are rich in collagen. Eat a balanced diet, eat more antioxidant foods, such as carrots and tomatoes, and drink some red wine and tea, because they can protect the collagen of the skin.
