Science
Mechanism of Action
This extract functions primarily through its rich astaxanthin content, a powerful carotenoid antioxidant. Astaxanthin actively neutralizes free radicals, thereby protecting skin cells from oxidative stress induced by solar radiation and environmental aggressors. It also contributes to mitigating inflammation, stimulating dermal collagen synthesis for enhanced firmness and elasticity, and bolstering the skin's natural barrier function. Its fatty acid composition further soothes environmentally compromised skin, and it has demonstrated the capacity to repair UVB-induced skin damage and aging by sustaining low oxidative stress levels and promoting collagen production.

Dusting Analysis
Haematococcus Pluvialis Extract is not commonly 'dusted' as its potent active component, astaxanthin, demonstrates significant efficacy at relatively low concentrations. The FDA has recognized its safe use in cosmetics up to 0.19% in specific product categories, indicating effective activity within this range without necessitating excessive concentrations for benefits.
The Formula
Formulation
Stability
Astaxanthin, the primary active, exhibits inherent instability, necessitating advanced delivery systems like encapsulation (e.g., liposomes or microcapsules) for improved stability and functional integration. Astaxanthin microcapsules show optimal pH stability around 6, followed by 5 and 4. Stability and antioxidant activity are significantly enhanced at 4°C compared to 20°C, and decrease proportionally with extended storage duration.
Safety
Safety Profile
Haematococcus Pluvialis Extract is widely considered safe for cosmetic application, typically used within concentrations of 0.1–2%. The FDA has affirmed astaxanthin derived from Haematococcus pluvialis as Generally Recognized As Safe (GRAS) for specific food uses at levels up to 0.15 mg astaxanthin per serving. In cosmetic products, FDA reported maximum concentrations include 0.1% for makeup bases and up to 0.19% for non-spray face, neck, and moisturizing products.
