Collagen is a very important ingredient in our skin.
At a young age the skin is stronger, more elastic, smoother and wrinkle-free. However, over the years collagen formation decreases, the skin begins to dehydrate, becomes drier and tends to create wrinkles. The connective tissue under the upper layer of the skin in young people consists of 80% collagen, but at the age of 25 its production declines.
