Rh-Polypeptide-11

Rh-Polypeptide-11 is a synthetic peptide — a chain of amino acids designed to mimic natural protein structures found in skin. Peptides function as signalling molecules and conditioning agents, helping to support the skin's barrier and overall appearance.In skincare formulations, this ingredient works primarily as a skin conditioner, helping to improve texture and maintain skin suppleness. It is typically used in modest concentrations within moisturisers, serums, and treatment products.

Peptides like Rh-Polypeptide-11 are thought to work through multiple mechanisms. They can form a conditioning film on the skin surface, improving hydration and tactile softness. At a deeper level, peptides may communicate with skin cells, potentially triggering responses that support collagen maintenance and skin resilience.The ingredient is particularly relevant to ageing skin, where loss of structural proteins — especially collagen — contributes to visible changes. By providing amino acid-based support, peptides may help address some of the underlying causes of age-related skin changes.

Rh-Polypeptide-11 is typically found in serums, moisturisers, and treatment products designed for mature or condition-specific skin. It can generally be used daily as part of your regular routine, either morning or evening. Peptide products often work best when layered with complementary ingredients such as hydrators or antioxidants, and consistency of use will yield better results than occasional application.

Peptides are generally well-tolerated by most skin types, including sensitive skin. As with any new product, perform a patch test first, particularly if you have a history of reactivity.
