What is elastin?

Elastin is a vital protein that contributes to the elasticity and resilience of various tissues in the body, especially within the skin, lungs, and blood vessels. It allows these tissues to return to their original shape after being stretched or contracted, which is essential for maintaining structural integrity and flexibility. This protein works synergistically with collagen, another key protein that provides strength and support.

The correct choice highlights that elastin is a protein base responsible for forming elastic tissue, which is crucial for the proper functioning of many bodily systems. Understanding this role is important for anyone in the beauty or wellness industry, as skin elasticity is central to aesthetics and overall skin health.
