Science
Mechanism of Action
Nostoc flagelliforme extract functions as a potent humectant, efficiently attracting and binding moisture to the skin, thereby enhancing its hydration levels. Its significant antioxidant capacity stems from a rich composition of polysaccharides, carotenoids, and mycosporine-like amino acids (MAAs), which actively neutralize damaging free radicals. The extract offers inherent UV protection, specifically against UV-B and short UVA radiation, through compounds like scytonemin and water-soluble MAAs. Additionally, its polysaccharides contribute to notable anti-inflammatory activities. This ingredient further promotes skin revitalization, aids in re-mineralization, and stimulates cellular renewal, culminating in a smoother and more supple skin texture.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has not specifically reviewed NOSTOC FLAGELLIFORME EXTRACT for topical use. While oral acute and 28-day subacute toxicity studies in rats showed no adverse effects at high doses (up to 2500 mg/kg), these assessments pertain to consumption and do not directly translate to cosmetic skin safety. No SCCS opinion or specific FDA cosmetic status has been found, indicating a lack of dedicated regulatory review for topical applications. Therefore, its sensitization risk and general skin safety profile for cosmetic use remain largely unknown based on current specialized data, though oral safety suggests a potentially favorable profile.
