Chlorella Vulgaris Methionyl Sh-Polypeptide-14 Hexapeptide-40

This ingredient is a peptide derived from chlorella vulgaris, a freshwater microalgae. Peptides are short chains of amino acids, and this particular complex combines a methionyl polypeptide with a hexapeptide fragment. It functions primarily as a multitasking ingredient in skincare formulations.In cosmetic formulations, it serves as an emulsion stabiliser—helping oil and water-based components remain blended—whilst also contributing antioxidant and antimicrobial properties. Because of its peptide structure, it may also have some conditioning effects on skin and hair.

As a peptide, this ingredient can interact with skin at a molecular level. Peptides are recognised by skin cells as signal molecules, which may trigger beneficial responses such as increased antioxidant activity or improved barrier function.Within a formulation, it acts as a stabiliser by reducing interfacial tension between oil and water phases, allowing products to remain homogeneous and effective for longer.

This ingredient is typically present in creams, serums, and emulsified products rather than being applied alone. Use the product as directed on the label. Because it works partly as a formulation stabiliser, consistency of use will allow the product to deliver its intended benefits over time.

Generally well-tolerated and considered safe for cosmetic use. Those with algae sensitivities should patch-test first.
