Collagen vs. Elastin: What's the Difference?

Edited by Aimie Carlson || By Harlon Moss || Updated on October 28, 2023
Collagen provides structure and strength to tissues; elastin offers elasticity and flexibility.

Key Differences

Collagen, a protein abundant in connective tissues, imparts strength and rigidity. Elastin, on the other hand, bestows flexibility, allowing tissues to resume their shape after stretching or contracting.
Collagen, the most plentiful protein in humans, forms the foundation of skin, bones, and tendons. Elastin is less abundant but critical in areas requiring elasticity, such as lungs, arteries, and skin.
Collagen's triple helix structure gives it tensile strength. In contrast, elastin's random coil configuration facilitates stretching and recoiling.
Aging leads to reduced collagen, causing wrinkles and weakened joints. Elastin deterioration also contributes to sagging skin and less resilient tissues.
Collagen is widely used in skincare and supplements for its perceived benefits to skin and joints. Elastin finds use in products aiming to enhance skin elasticity.
