Chlorella Vulgaris Sh-Polypeptide-14

Chlorella vulgaris sh-polypeptide-14 is a peptide derived from chlorella vulgaris, a nutrient-dense freshwater green algae. It is processed to extract bioactive compounds including polysaccharides, polyphenols, and chlorophyll, which are then stabilised in a peptide form for use in skincare formulations.In cosmetics, this ingredient functions primarily as a skin conditioner and antioxidant, helping to support the skin's natural defences against environmental stressors. It also has antimicrobial properties, making it relevant for formulations targeting sensitivity or reactive skin.

The peptide components are small enough to penetrate the outer layers of skin, where they deliver the algae's bioactive compounds. These compounds work primarily through antioxidant mechanisms, neutralising reactive oxygen species that contribute to skin ageing and inflammation.The polysaccharides and polyphenols within the extract also interact with the skin barrier, helping to support hydration and reduce transepidermal water loss. This combination of mechanisms makes it particularly relevant for compromised or sensitive skin conditions.

This ingredient is typically incorporated into serums, moisturisers, and targeted treatments for sensitive or reactive skin. It works well alongside other skin-conditioning and antioxidant ingredients but does not require special handling or timing. Use as directed within your chosen product formulation.

Chlorella vulgaris derivatives are generally well-tolerated and suitable for most skin types, including sensitive skin. As with any new ingredient, patch test first if you have known sensitivities to algae-derived products.
