Spirulina Platensis Extract
What Spirulina Platensis Extract is & what it does
Spirulina Platensis Extract is derived from spirulina, a blue-green microalgae (cyanobacteria) grown in fresh or salt water. In skincare and sunscreen formulas it acts as a conditioning and antioxidant ingredient, contributing proteins, vitamins, and pigments such as phycocyanin and chlorophyll. It is often included for its rich amino acid and micronutrient profile that supports the skin's surface.
