Arthrospira Platensis Extract

Arthrospira platensis extract comes from a cyanobacterium (microalga) that has been used nutritionally for centuries, particularly in East Asian and African communities. The extract is rich in proteins, lipopolysaccharides, and gamma-linolenic acid—compounds that contribute to its activity in skincare formulations.In cosmetic products, it functions primarily as an antioxidant and skin conditioner. The extract contains phytochemical compounds including phenolic and flavonoid compounds, which help protect skin and support hydration.

The extract's antioxidant activity stems from its high concentration of phenolic and flavonoid compounds. These molecules are structurally designed to donate electrons to free radicals, stabilising them and preventing them from damaging skin cells and collagen.As a humectant, the extract draws water into the skin's outer layers, supporting hydration. The presence of lipopolysaccharides and proteins also contributes to skin conditioning, helping maintain the skin's natural texture and resilience.

Arthrospira platensis extract is typically used in serums, creams, and conditioning products. As with any new skincare ingredient, introduce it gradually to assess tolerance. It pairs well with other antioxidants and hydrating ingredients. No specific usage frequency restrictions are documented, so follow the product instructions.

Generally well-tolerated. Those with sensitivities to algae-derived ingredients should patch test first. No major contraindications are documented for topical use.
