Which protein gives skin its elasticity and flexibility?

Skin’s ability to stretch and snap back is due to elastin fibers in the dermis. Elastin acts like tiny springs, allowing the skin to deform and then return to its original shape, which gives both elasticity and a sense of flexibility. Collagen, on the other hand, provides structural strength and helps resist tearing, giving firmness but not the same stretchiness. Keratin is a protective protein mainly in the epidermis and in hair and nails, so it doesn’t contribute to skin elasticity. Fibrin is involved in blood clotting, not the skin’s connective matrix. So elastin is the protein responsible for the skin’s elasticity and flexibility.
