Acetyl Tripeptide-30 Citrulline (INCI Acetyl Tripeptide-30 Citrulline) is a synthetic tripeptide with a citrulline residue and an acetyl protection. It is added to anti-ageing formulas as a signalling ingredient that, by the developer's design, supports firmness and skin renewal. On efficacy, honestly and without overstatement: there is little data, almost all from the raw-material supplier, with few independent clinical studies. This is a supporting ingredient in a formula, not a proven standalone active. It can complement a routine, but it does not replace proven actives such as retinoids or vitamin C. During pregnancy and breastfeeding it can be used. The peptide molecule is large, it does not penetrate the skin systemically when applied topically, and there are no restrictions. Tolerance is good. The irritation potential is low, the allergy risk is low, and the ingredient suits sensitive skin. Peptides of this class behave calmly even on reaction-prone skin.
