Introduction
Elastin peptide, also known as elastin, is a hard protein primarily present in connective tissue, particularly in the elastic tissues of tendons and arteries. Its peptide chain contains a large number of hydrophobic amino acids, which form tight interactions within the molecule, giving elastin its unique physical properties.
Rich in glycine and proline: The amino acid sequence of elastin contains glycine, which accounts for nearly one-third of the total, and proline, which makes up 10%. These two amino acids are crucial for forming its unique three-dimensional structure.
Lack of hydroxyproline: Unlike collagen, elastin does not contain hydroxyproline.
Structure characteristics
Lack of continuous repetitive periodic structure: The amino acid sequence of elastin does not have a continuous repetitive periodic structure that runs through the entire peptide chain, but there are alternating hydrophobic and hydrophilic segments.
Unique cross-linking structure: Chains and open chain chains formed by oxidized lysine are unique cross-linking structures of elastin, which bind multiple elastin fibers together to form a stable network structure.
Secondary and tertiary structures
Irregular Curling: The secondary structure of elastin may be a combination of irregular curling and ordered structure.
Elasticity: The most important physicochemical property of elastin is its elasticity, mainly due to the cross-linking network within its molecules that can generate elasticity through conformational changes.
Cross-linked network
Complex cross-linking network: The cross-linking between elastin molecules is more complex than collagen, forming an elastic network structure through cross-linking involving lysine residues. These cross-linking networks can generate elasticity through conformational changes.
In summary, the structural characteristics of elastin peptides are high hydrophobicity, unique cross-linking structure, irregularly coiled secondary structure, and complex cross-linking network, which together endow elastin with its unique physical properties and functions.

Functions
Elastin Peptide is a protein that contains amino acids such as glycine,alanine,valine and proline in larger percentages
1.Moisturizing and whitening skin:
The unique structure of it can strongly lock water, avoid the outflow of water, and keep the skin wet and white; And it has a lot of hydroxyl groups, which can not only improve the skin chroma, but also remove whitening
2.Desalination of senile plaque:
It can reasonably inhibit tryptophan enzyme activity and reduce the cause of pigment
3.Anti aging:
Repair the broken and brittle elastic fiber net, repair the skin's ductility, flush the flexibility, make the skin more malleable and make the chest more malleable; In addition, it can remove oxygen free radicals from the body, resist oxidation in many ways, and alleviate skin aging
4.Repair cells:
The formation of wrinkles and slight wrinkles is related to the outflow of it. After supplementing it, it can immediately penetrate into the skin dermis, reorganize the skin chemical fiber tissue, and promote the basic metabolism of somatic cells. It can reasonably maintain the skin fiber cells after being directly exposed to ultraviolet light and reduce the dissolution of collagen powder, It can reasonably inhibit the activity of tryptophan enzyme, block the production of pigment and reduce the production of melanin in the skin. In addition, it can reasonably inhibit the glycosylation effect in the human body.
Applications
• Nutricosmetics (Oral Beauty): Anti-aging drinks, powder sachets, and capsules.
○ Claim: "Restores the Bounce" and "Defies Gravity."
• Topical Cosmetics: Firming creams, neck lifting serums, and eye contour gels.
○ Why it works: Film-forming properties provide an immediate tightening sensation upon application.
• Hair Care: Elasticity-boosting hair masks to reduce breakage in chemically treated hair.

FAQ
Why is the "Arterial Bulb" source better?
The arterial bulb (heart vessel) of the fish is the tissue with the highest concentration of pure elastin fibers (elastic tissue) compared to skin or scales, which are mostly collagen. This ensures a higher content of Desmosine.
What is the recommended dosage?
For oral supplements: 100mg - 500mg per day. For topical cosmetics: 0.1% - 1.0%.
Can I combine this with Collagen in a formula?
Yes, it is highly recommended. A "Beauty from Within" formula typically combines 5000mg Collagen with 100mg Elastin to target both density and elasticity.
