Tripeptide-29 is a vegan, biomimetic peptide composed of glycine, proline, and hydroxyproline—three essential amino acids that form the building blocks of human collagen.

It acts on dermal fibroblasts, participating in the regulation of collagen synthesis signals, helping to enhance the efficiency of type I collagen production, while moderately inhibiting MMP-1 metalloproteinase activity, reducing excessive collagen degradation, and helping to maintain the stability of the dermal reticular structure.

Tripeptide-29 has a low molecular weight and high transdermal absorption efficiency, allowing it to be directly recognized and utilized by the skin. It is now widely used in various functional skincare products.
