Collagen (collagen) is a biological polymer substance, a white, opaque, unbranched fibrous protein. It can replenish the nutrients needed for each layer of the skin, enhance the collagen activity in the skin, moisturize the skin, delay aging, beauty, wrinkle, and hair growth.

Skin growth, repair, nutrition, elasticity, and tension are all closely related to collagen. 75% of the dermis is made up of collagen, which is responsible for the two main missions of anti-wrinkle and moisturizing. The human body can produce a lot of collagen when it is young, but their yield will gradually decrease with age. When women are 20 years old, collagen begins to age and lose. At the age of 25, it enters the peak of loss. At 40 years old, it is less than half of that when it is 18 years old.
