Spirulina platensis is a cyanobacteria biomass rich in proteins (60–70%), phycocyanin, chlorophyll, carotenoids, and essential fatty acids. Used as a natural blue-green pigment with documented antioxidant and anti-inflammatory bioactivity, it is positioned in cosmetics as a functional active rather than a decorative colorant. Optimal stability is at pH 6–7 under cold processing (<40 °C). It aligns strongly with clean-label, vegan, and sustainable trends
Dunaliella salina is a halotolerant microalgae extract rich in carotenoids, primarily β-carotene in both all-trans and 9-cis forms, along with lutein and zeaxanthin. These compounds provide effective lipid-phase antioxidant protection
Astaxanthin from Haematococcus pluvialis is a highly potent, esterified carotenoid antioxidant—20–50× stronger than synthetic forms—offering exceptional stability, bioavailability, and broad health benefits. Clinically proven to protect cardiovascular, ocular, muscular, and
AlgaeTech™ Porphyridium is derived from the red microalga Porphyridium cruentum. This ingredient creates a natural polysaccharide shield that protects skin cells and enhances hydration. Rich in sulfated polysaccharides, proteins, sugars,
