Acetyl Tripeptide-30 Citrulline is a synthetic peptide that has gained popularity in the cosmetic industry for its skin conditioning properties. It is known for its ability to prevent the degradation of extracellular matrix components that are disrupted during the formation of stretch marks and to prevent the formation of new stretch marks by strengthening the skin's ability to withstand distension. This peptide has been reported to help the skin recover its elasticity, visibly attenuating stretch marks, and contributing to smoother and more even skin. It is also described as a new synthetic tetrapeptide that selectively inhibits human matrix metalloproteinases (MMPs), which are enzymes that can break down proteins in the extracellular matrix, leading to skin aging and other conditions. Synonyms: Acetyl Tripeptide-30 Citruline; Lys-α-Asp-Ile-Citrulline; (2S,5S,15S)-15-Amino-2-((S)-sec-butyl)-5-((S)-2,6-diaminohexanamido)-4,7,10-trioxo-8-oxa-3,9,11-triazahexadecanedioic acid; Lys-Asp-{Ile-Citrulline}; KD-{Ile-Citrulline}; Lys-Asp-{Ile-Cit}.
