A numbered tripeptide for skin-conditioning claims. Gentle class, supplier-led evidence.
Tripeptide-128 is an INCI-numbered proprietary tripeptide. Tripeptides as a class are widely used in cosmetic actives (e.g., copper tripeptide-1 has a substantial independent literature); this specific numbered grade relies on supplier data. No CIR or SCCS monograph. Used at ppm active levels for signaling claims — firmness, elasticity, or soothing depending on sequence.
