What Is Sh-Polypeptide-47?
Sh-Polypeptide-47 is a peptide—a short chain of amino acids—designed to function as a skin conditioning agent. Peptides are naturally occurring in the skin and play a role in maintaining its structure and resilience. This particular peptide is included in skincare formulations to support the skin's barrier function and overall condition.
As a skin conditioning ingredient, Sh-Polypeptide-47 works to help maintain skin hydration and improve the feel and appearance of the skin. Peptides are of particular interest in skincare because the skin's natural peptide and protein content—particularly collagen—declines with age, contributing to visible changes in firmness and texture.
How It Works
Peptides work by mimicking or supporting the skin's natural amino acid profile. When applied topically, Sh-Polypeptide-47 is thought to integrate into the skin's upper layers where it reinforces hydration and the skin's natural conditioning processes. The ingredient does not penetrate deeply into the dermis, but rather works at the surface to enhance skin condition and resilience.
By supporting the skin's moisture barrier and structural integrity, this peptide may help counteract some of the visible effects of ageing and environmental stress, which compromise skin thickness and hydration over time.
Clinical Evidence & References
Research on skin ageing confirms that the progressive loss of collagen and other structural proteins—along with thinning of the epidermis and dermis—underlies visible signs of ageing such as loss of firmness, fine lines, and impaired barrier function. Peptides are included in skincare formulations based on the rationale that they can help support and condition the skin as its natural protein content declines.
However, specific clinical evidence for Sh-Polypeptide-47 is limited. General peptide research suggests benefits for skin conditioning and hydration, but individual peptides vary in efficacy. More focused research on this particular ingredient would help clarify its effectiveness in clinical settings.
How to Use
Sh-Polypeptide-47 is typically found in serums, moisturisers, and treatment products. Apply to clean skin before heavier creams to allow the peptide to absorb efficiently. It can be used daily as part of a routine. For best results, combine with other supportive ingredients such as hydrators and antioxidants, and maintain consistent sun protection to minimise further collagen breakdown.
