Sr-Clostridium Botulinum Polypeptide-1 Sh-Oligopeptide-1

Sr-Clostridium Botulinum Polypeptide-1 Sh-Oligopeptide-1 is a peptide derived from bacterial sources and engineered for cosmetic use. Despite its origin, it contains no active toxin and is used solely for its antioxidant and skin-protective properties in skincare formulations.Peptides are short chains of amino acids that can interact with skin cells. This particular ingredient is included in formulas to help neutralise free radicals and support the skin's natural defence mechanisms against environmental stressors.

The ingredient functions primarily through its antioxidant capacity—donating electrons to neutralise unstable free radical molecules that would otherwise damage skin cells and collagen. This helps reduce oxidative stress, a key driver of premature ageing and inflammation.As a peptide, it may also interact with skin cells to upregulate protective proteins and enhance barrier function, though the precise mechanisms in living human skin remain incompletely understood.

This ingredient is typically found in serums, moisturisers, and protective creams. Use it as directed by the product instructions—usually once or twice daily. It pairs well with other antioxidants (such as vitamin C or niacinamide) and is generally compatible with most skincare routines. Allow time between application and sun exposure for full protective benefit if used in a daytime product.

Generally well-tolerated in cosmetic concentrations. Sensitivity is rare, but those with peptide sensitivities or bacterial-derived ingredient concerns should patch-test first.
