Science
Mechanism of Action
This extract functions as a highly effective humectant due to its hygroscopic nature, attracting and retaining moisture to enhance skin smoothness and suppleness. It is noted for stimulating microcirculation and accelerating cellular renewal, promoting skin revitalization and re-mineralization. Key components, similar to related brown algae, include water-loving alginates that form a protective, moisturizing film; laminarin, which offers decongestant and lipid-balancing actions; and phenolic compounds, providing antioxidant defense and aiding in the sequestration of heavy metal ions to protect against environmental stressors.

Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded in 2019 that current data are insufficient to support a safety conclusion for Saccharina Angustata Extract, primarily due to a lack of systemic toxicity and dermal sensitization data. However, a mixture containing 0.83% of this extract was documented to contain less than 20 ppm heavy metals and not more than 5 ppm arsenic.
