Antioxidant Anti-inflammatory Antimicrobial Antibacterial Moisturizing Hydrating Anti-aging Skin Protecting Collagen Boosting Cell Renewal Sebum Balancing pH Balancing UV Absorber Detoxifying

Science

Mechanism of Action

This ingredient functions through a rich array of bioactive compounds, including phycocyanin, carotenoids, polyphenols, flavonoids, tannins, and vitamins (A, B, C, E). These components collectively provide potent antioxidant protection against free radical damage and oxidative stress. It also exhibits anti-inflammatory and soothing capabilities by inhibiting compounds responsible for skin sensitivity, thereby diminishing irritation and redness. Its antimicrobial and antibacterial activities effectively target common skin pathogens like *Staphylococcus aureus* and *Cutibacterium acnes*, supporting acne treatment. Furthermore, Spirulina Platensis Powder enhances skin hydration by improving water-binding capacity and reducing transepidermal water loss. For anti-aging benefits, it promotes cellular renewal, stimulates fibroblast growth, boosts collagen production, and inhibits enzymes that degrade elastin. Additional properties include detoxification, improved blood microcirculation, and support for a balanced skin barrier through sebum and pH regulation.
