Science
Mechanism of Action
This ingredient provides broad-spectrum benefits by alleviating cellular hypoxia, reducing oxidative stress, and mitigating inflammation. Its C-phycocyanin content stimulates fibroblast proliferation and migration via the PI-3K pathway, boosting collagen production and tissue formation. The extract actively modulates the skin's microbiota, exhibiting concentration-dependent effects on microbial growth, and possesses both antibacterial and antiviral properties. Furthermore, it delivers anti-acne benefits through various compounds like phenols and saponins, offers photoprotection by inhibiting tyrosinase and free radicals, and supports healing by reducing pro-inflammatory cytokines while enhancing angiogenesis and cellular proliferation. It also activates the Nrf2/HO-1 pathway for robust antioxidant defense.

Dusting Analysis
Data is insufficient to determine if Hydrolyzed Arthrospira Extract is commonly 'dusted' or to establish a dusting threshold.
The Formula
Formulation
Stability
The key component C-phycocyanin maintains high hydrophilic stability in a pH range of 5 to 8. Enzymatic hydrolysis for protein hydrolysates typically optimizes between pH 6.5 and 9.0. An optimal cream formulation with Spirulina extract was achieved at pH 7.11, suggesting good stability within a neutral to slightly alkaline environment.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) and Scientific Committee on Consumer Safety (SCCS) have not specifically evaluated Hydrolyzed Arthrospira Extract. However, 'Spirulina Extract' (biomass) holds FDA exemption as a color additive with specific usage limits. Safety studies on phycocyanin-containing Arthrospira extracts (2.3 g/day) support a Generally Recognized As Safe (GRAS) status for dietary use, indicating a low risk for topical application. Arthrospira platensis biomass is generally considered safe for human consumption with rare adverse reactions; however, sourcing is crucial due to potential heavy metal contamination from open-water cultivation.
