Sh-Polypeptide-77

Sh-Polypeptide-77 is a peptide—a short chain of amino acids—used in skincare formulations primarily for its skin conditioning properties. Peptides are fragments of proteins that can penetrate the skin's outer layers and communicate with skin cells, potentially influencing how the skin behaves and maintains its appearance.This ingredient functions as a skin conditioning agent, meaning it works to improve the texture, feel, and overall condition of the skin. It is typically incorporated into serums, moisturisers, and treatment products at relatively modest concentrations.

Peptides work by penetrating the outer layers of the skin and communicating with skin cells through receptor-binding. Sh-Polypeptide-77 is believed to signal to the skin to maintain or enhance its natural production of structural proteins, particularly those involved in firmness and elasticity.The peptide also supports the skin's barrier function and hydration capacity, which are essential for healthy skin appearance. By reinforcing these foundational skin properties, the ingredient may help address visible signs of aging and maintain skin resilience over time.

Sh-Polypeptide-77 is typically found in serums and moisturisers designed for mature or aging skin concerns. Apply to clean skin before heavier creams or oils to maximise penetration. It can be used daily as part of your regular skincare routine and pairs well with complementary ingredients such as hydrators and antioxidants.

Peptides are generally well-tolerated and considered safe for topical use. Those with known sensitivities to amino acids or peptide-based ingredients should patch-test first.
