Haematococcus Pluvialis (Algae) Extract
What is Haematococcus Pluvialis (Algae) Extract?
Haematococcus pluvialis is a freshwater microalga that produces astaxanthin, a powerful carotenoid antioxidant, particularly when exposed to environmental stresses like intense light or nutrient scarcity. This extract is derived from the algae's biomass, typically through solvent or supercritical CO2 extraction, yielding a reddish concentrate rich in this pigment alongside other carotenoids, vitamins, and lipids. In cosmetics, it belongs to the skin conditioning and antioxidant categories, commonly used in anti-aging serums, moisturizers, and protective creams. It functions by scavenging free radicals, preventing lipid peroxidation in formulations to enhance stability, and providing a protective layer on skin against oxidative environmental factors. Valued for its natural origin, it's integrated at trace levels to leverage its superior electron-donating capacity compared to other antioxidants like vitamin E.
