Sh-Polypeptide-8

Sh-Polypeptide-8 is a peptide—a short chain of amino acids—used in skincare formulations as a humectant and skin conditioning agent. Peptides are naturally occurring in the skin and play a role in maintaining its structure and function. This ingredient works by drawing moisture into the skin and helping to improve its overall condition and appearance.As a humectant, it attracts water to the skin's surface, which can help maintain hydration levels. Its skin conditioning properties mean it helps to soften and smooth the skin's texture, supporting the skin barrier's natural resilience.

Sh-Polypeptide-8 functions primarily as a humectant, meaning it has an affinity for water molecules and draws them from deeper skin layers and the environment toward the surface. This helps to plump and hydrate the epidermis, which can temporarily improve the appearance of fine lines and create a smoother skin surface.The peptide also conditions the skin by interacting with the outer layers, helping to improve softness and elasticity. While the exact mechanism of how this specific peptide influences skin structure remains an area for further research, peptides in general are thought to supp…

Sh-Polypeptide-8 is typically found in serums, moisturisers, and hydrating treatments. Apply to clean, damp skin to maximise the humectant effect—the moisture on your skin gives the peptide more water to draw in and distribute. Layer it under an occlusive moisturiser or oil to seal in hydration, particularly if you have dry skin. It can be used alongside other conditioning and hydrating ingredients without concern.

Sh-Polypeptide-8 is generally well-tolerated across skin types. As with any ingredient, patch test first if you have very sensitive skin or known peptide sensitivities.
