Cladosiphon Novae-Caledoniae Polysaccharide

Cladosiphon Novae-Caledoniae Polysaccharide is a naturally derived carbohydrate extracted from brown algae native to New Caledonia. It belongs to a class of ingredients called polysaccharides, which are long-chain sugar molecules known for their ability to hold water and form protective layers on the skin.In skincare formulations, this ingredient functions as a humectant and skin protectant. Its polysaccharide structure allows it to draw moisture into the outer layers of skin whilst simultaneously helping to shield the skin barrier from environmental stressors.

As a humectant, Cladosiphon Novae-Caledoniae Polysaccharide works by binding water molecules and drawing them into the stratum corneum, the skin's outermost layer. This increases hydration and plumps the skin.Simultaneously, its film-forming properties create a lightweight protective layer across the skin surface. This barrier helps prevent moisture from evaporating and shields skin from environmental irritants, supporting the skin's natural defence mechanisms.

This ingredient works well in serums, moisturisers, and hydrating essences. It pairs effectively with other humectants like glycerine or hyaluronic acid, and with barrier-support ingredients such as ceramides or niacinamide. There is no need to layer it in any specific order, though applying it to damp skin may enhance its hydrating effect.

Generally well-tolerated across skin types. As with any ingredient, patch-test first if you have known sensitivities to algae or marine-derived compounds.
