collagen tripeptide + elastin peptide

Collagen tripeptide + elastin peptide is a combination of two bioactive peptides commonly used as dietary supplements, especially in products aimed at skin health and anti-aging. Collagen tripeptide consists of three amino acids derived from the hydrolysis of collagen, typically glycine, proline (or hydroxyproline), and another amino acid. It is characterized by its very low molecular weight (around 280 Da), which allows for rapid absorption and high bioavailability compared to larger collagen peptides or whole collagen protein[3][4][5][6]. Elastin peptide is derived from the enzymatic hydrolysis of elastin, a key protein responsible for skin elasticity. The combination aims to support skin structure by providing building blocks for both collagen and elastin fibers in the dermis. Mechanistically, these peptides are believed to promote fibroblast activity, stimulate new collagen synthesis, enhance hyaluronic acid production, improve skin hydration and elasticity, provide antioxidant effects, support bone strength and repair processes in connective tissues[4][5]. However, while some studies suggest potential benefits for skin appearance and joint health when taken orally as supplements or functional foods[7], robust clinical evidence remains limited. This combination is widely marketed in Asia—especially China—in oral liquid drinks or powders targeting beauty-from-within markets. It may also be found in topical cosmetic formulations.
