Elastin
The main elastic substance of skin can also extract elastic fiber from animals and plants. Adding elastic fiber to cosmetics can become a good water retaining agent. Hydrolyzed protein in animal connective tissue can restore the original shape of some human tissues after they are pulled or contracted, and help the skin recover its elasticity when it is damaged or depressed.
