Tripeptide-10 Citrulline

Tripeptide-10 Citrulline is a peptide combined with citrulline that works to regulate collagen fibril organisation in the skin. Rather than just stimulating more collagen, it helps ensure collagen is properly structured for optimal skin firmness.

This sophisticated approach to collagen management helps improve skin density and texture. The peptide is particularly effective at addressing the loss of skin quality that comes with ageing.

Tripeptide-10 Citrulline is a synthetic peptide, often marketed under the trade name Decorinyl, that is a modified tetrapeptide (lysine–asparagine–isoleucine–citrulline) designed to mimic the structure of the naturally occurring protein **decorin**. Decorin plays a crucial role in regulating the formation and organization of collagen fibers in the skin, which is vital for maintaining skin elasticity and firmness. Tripeptide-10 Citrulline works by binding to the collagen fibers, helping to regulate their size and spacing, leading to a more uniform and thinner collagen network. This action is reported to improve the overall suppleness and elasticity of the skin and has been shown to have anti-wrinkle efficacy in clinical studies. Compared to its precursor, Tripeptide-10, the citrulline modification is noted to be more stable and effective.
