Sr-Cat Polypeptide-1

Sr-Cat Polypeptide-1 is a synthetic peptide — a short chain of amino acids — created to mimic or support natural skin-protecting processes. Peptides are increasingly used in skincare because they're small enough to penetrate the outer layers of skin, where they can interact with cells and potentially influence skin behaviour.This ingredient is categorised as a skin protectant, meaning its intended function is to help maintain or strengthen skin's defensive barriers rather than to treat specific concerns like acne or pigmentation.

Sr-Cat Polypeptide-1 works by engaging with skin cells at a molecular level. As a peptide, it can penetrate the stratum corneum (the outermost skin layer) and communicate with deeper skin structures, potentially signalling cells to maintain or enhance protective functions.The exact mechanism remains somewhat proprietary to formulation developers, but peptides in general are thought to stimulate natural skin processes that support barrier integrity and resilience.

Sr-Cat Polypeptide-1 is typically incorporated into serums, moisturisers, or treatment creams. Use it as directed by the product formulation — usually once or twice daily as part of your regular routine. It pairs well with other barrier-support ingredients like ceramides or niacinamide, and should be applied to clean skin before heavier creams.

Peptides are generally well-tolerated across most skin types. As with any new ingredient, introduce it gradually and discontinue if irritation occurs. No specific contraindications are documented for Sr-Cat Polypeptide-1.
