What Is Sr-Hydrozoan Polypeptide-1?
Sr-Hydrozoan Polypeptide-1 is a peptide derived from hydrozoan organisms, formulated to provide multiple skincare functions. Peptides are short chains of amino acids that can interact with the skin's surface and deeper layers to support structural integrity and hydration.
This ingredient functions as a film former, humectant, and skin conditioner, meaning it can help coat the skin, draw moisture into the outer layers, and improve overall skin feel and texture. It also offers some UV-filtering properties, though it is not typically used as a primary sun protection ingredient.
Benefits for Your Skin
How It Works
As a humectant, Sr-Hydrozoan Polypeptide-1 attracts water molecules from the environment and the deeper layers of skin, drawing them into the stratum corneum (the outermost skin layer). This hydrating action can plump the skin surface temporarily and support a smoother appearance.
The film-forming capacity creates a lightweight protective layer on the skin, which can reduce moisture evaporation and improve skin feel. The peptide structure may also interact with skin proteins, though the extent and significance of these interactions in cosmetic concentrations remain an area for further study.
Clinical Evidence & References
Research into hydrozoan-derived peptides in cosmetics remains limited. While peptides as a category have demonstrated benefits for skin hydration and conditioning in topical formulations, specific evidence for Sr-Hydrozoan Polypeptide-1 is sparse. Most supporting data comes from ingredient supplier studies rather than independent peer-reviewed research.
The ingredient's film-forming and humectant properties are consistent with established peptide chemistry, but claims around anti-ageing benefits should be approached with caution. More robust clinical data would be needed to substantiate effects on fine lines or skin firmness beyond temporary surface hydration.
How to Use
This ingredient is typically found in hydrating serums, moisturisers, and conditioning treatments. It works well in layered routines and pairs effectively with other humectants such as glycerin or hyaluronic acid. Apply to damp skin to maximise the humectant effect, or use in formulations that support skin hydration throughout the day.
