Sh-Polypeptide-19

Sh-Polypeptide-19 is a peptide—a short chain of amino acids—designed to function as a skin conditioning agent. Peptides are naturally occurring compounds found throughout the body, and those used in skincare are typically derived synthetically or extracted from biological sources to support skin's structural integrity.In formulations, this ingredient works primarily as a skin conditioner, helping to improve how skin feels and appears by supporting the skin's natural protein matrix.

Peptides like Sh-Polypeptide-19 function by interacting with the skin's surface and upper layers. They support the skin's natural proteins—particularly collagen and elastin—which are responsible for skin structure, firmness, and suppleness.As a skin conditioner, this peptide helps to optimise how the skin feels and behaves, rather than driving dramatic biochemical change. The mechanism involves supporting the skin's existing structural framework and improving hydration and texture at the surface level.

This ingredient is typically found in serums, moisturisers, and targeted treatment products. Apply to clean skin as part of your regular routine. It pairs well with other conditioning and hydrating ingredients, and there are no known interactions with common skincare actives. Use consistently for best results, as conditioning benefits develop over time with regular application.

Peptides are generally well-tolerated by most skin types. No significant safety concerns have been identified. Those with very sensitive skin should patch test, as with any new ingredient.
