What Is Rice Sh-Polypeptide-1?
Rice SH-Polypeptide-1 is a peptide derived from rice, created through the breakdown of rice proteins into smaller amino acid chains. Peptides are fragments of proteins that can penetrate the skin's outer layers more easily than whole proteins, making them useful in skincare formulations.
In skincare, this ingredient functions primarily as a humectant (drawing moisture into the skin), an opacifying agent (adding opacity to formulations), and a skin conditioner. It helps maintain skin hydration and supports the skin's overall moisture balance.
How It Works
As a humectant, Rice SH-Polypeptide-1 works by attracting water molecules from the deeper layers of skin and the environment, then binding them to the outer layers. This helps maintain skin hydration and can improve skin suppleness.
The peptide structure allows it to interact with the skin's surface, conditioning and smoothing the appearance of skin whilst contributing to formulation texture and stability.
Clinical Evidence & References
Rice-derived ingredients have been studied for their potential benefits in skincare, with research suggesting anti-inflammatory, moisturising, and skin-conditioning properties. However, specific clinical evidence on Rice SH-Polypeptide-1 as an isolated ingredient is limited, and most supporting data comes from broader research on rice-derived compounds rather than this peptide in particular.
The ingredient appears well-tolerated in formulations, though individual studies directly measuring its efficacy would strengthen the evidence base. It is best considered as a supportive hydrating and conditioning ingredient rather than a targeted treatment.
How to Use
Rice SH-Polypeptide-1 is typically found in serums, moisturisers, and hydrating treatments. Use daily as part of your regular skincare routine, applying to clean skin before heavier creams or oils. It works well in layered routines and pairs effectively with other hydrating ingredients.
