What Are Elastin Fibers Made Of?
Elastin fibers are made of a protein called elastin. Elastin is an essential component of many connective tissues in the body such as skin, arteries, lungs, and ligaments. These fibers provide elasticity, allowing the tissues to stretch and recoil back to their original shape. Elastin production decreases with age, leading to a loss of elasticity in the skin and other tissues.
