Science
Mechanism of Action
This extract functions as a robust antioxidant, effectively neutralizing detrimental free radicals and mitigating ROS-induced cellular damage, thereby safeguarding the skin from premature aging and oxidative stress. Its anti-inflammatory prowess is demonstrated by its ability to suppress NLRP3 inflammasome activation and reduce pro-inflammatory cytokine expression, leading to a calmer, less stressed dermal environment. Spirulina Maxima Extract also stimulates cell division, promoting renewal and regeneration, which enhances skin smoothness, elasticity, and tone, while fostering increased collagen production for improved wound healing. Furthermore, it acts as an exceptional moisturizer and skin conditioning agent, bolstering the skin's natural barrier function by maintaining hydration, reducing transepidermal water loss, and improving the hydrolipidic balance. It exhibits antibacterial activity against common skin flora like Propionibacterium acne and Staphylococcus epidermidis, assisting in the management of blemishes, and may also contribute to reducing skin hyperpigmentation.

Key findings
- 01 In a controlled study, Spirulina Maxima Extract at a concentration of 33.5 µg/mL significantly stimulated cell growth, leading to a 100% to 270% increase in cell activity after 72 hours.
- 02 Cosmetic formulations containing Spirulina dry extract within a range of 0.1% to 5.0% have demonstrated efficacy for anti-aging, hydration, and general skin improvement. Specifically, concentrations of 1.40% or 1.58% were effective in inhibiting 50% of free radicals.
- 03 An in vitro study utilizing a skin cream incorporated with 1.125% crude extract of Spirulina platensis (a related species) showed enhanced wound healing effects on keratinocyte cell lines and increased collagen production.

Safety
Safety Profile
While Spirulina extract (specifically Arthrospira platensis) holds Generally Recognized As Safe (GRAS) status and is FDA-approved as a color additive for certain food and drug applications, Spirulina Maxima Extract as a cosmetic ingredient has not been directly reviewed by the CIR. It is generally considered safe for topical use; however, individuals with sensitivities to cyanobacteria are advised to perform patch testing. Concerns regarding potential contamination from toxic impurities or hazard labeling often relate to raw or unpurified algae, rather than the purified extract used in quality cosmetic formulations.
