Science
Mechanism of Action
This extract leverages sulfated polysaccharides and polyphenols to benefit the skin. Polysaccharides reduce inflammation by mitigating cytokine activity, which diminishes redness and irritation. Their mucilaginous carrageenan content also imparts soothing and moisturizing properties. Additionally, these compounds enhance local immune responses and exhibit antiviral activity by forming a protective barrier and inhibiting viral replication. Polyphenols offer potent antioxidant protection, neutralizing free radicals and safeguarding skin cells from oxidative stress. Together, these components also contribute to accelerated wound healing through stimulated collagen synthesis and promoted cellular renewal.

Stability
While specific optimal pH for Gigartina Skottsbergii Extract's stability is not broadly available, studies on related red seaweed pigments (phycoerythrins) suggest good stability within a pH range of 4 to 10. Degradation of these pigments was noted at pH 2 and pH 12.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel's March 2021 Draft Final Report determined that data for Gigartina Skottsbergii Extract, among other red algae-derived ingredients, were insufficient to conclusively assess safety. This assessment highlighted a lack of comprehensive systemic toxicity (e.g., oral or food-related) and sensitization data.
