Elastin

What Is Elastin?

Elastin is a highly cross-linked fibrous structural protein found in the extracellular matrix of connective tissues. It is primarily extracted from bovine ligamentum nuchae, with other sources including porcine aorta, poultry skin, and fish aorta. The key active components are desmosine and isodesmosine, unique cross-linking amino acids responsible for elastin's remarkable elasticity. Through enzymatic hydrolysis, elastin can be broken down into hydrolyzed elastin and elastin peptides with low molecular weights (below 1,000 Da), making them water-soluble and highly bioavailable for cosmetic and nutritional applications.

Elastin peptides with a molecular weight of 500–1000 Da are primarily used in anti-aging skincare formulations, oral beauty supplements, and tissue engineering applications, where their small molecular size enables effective skin penetration and high bioavailability.

Product Applications

Supports skin elasticity:

Elastin peptides are designed to help maintain the skin's natural elasticity and improve the appearance of skin firmness.

Helps reduce the appearance of fine lines and wrinkles:

Hydrolyzed elastin helps replenish the skin's elastin network, contributing to a smoother, more youthful-looking complexion.

Helps maintain skin hydration:

Hydrolyzed elastin forms a breathable film on the skin surface, helping to reduce moisture loss and support long-lasting hydration.

Supports skin barrier function:

Elastin is a natural component of the skin's extracellular matrix and may help support the skin's structural integrity and barrier resilience.

Promotes skin renewal:

Elastin plays a role in supporting the skin's natural repair processes, helping to maintain a healthy, revitalized appearance.
