Science
Mechanism of Action
This marine extract functions as a comprehensive skin conditioning agent, meticulously maintaining skin integrity and enhancing its texture. It works to soften, smooth, and deeply hydrate the skin, visibly improving its overall feel and radiance. By forming a subtle, invisible barrier, it effectively locks in essential moisture, leading to a plumper and more supple complexion. Its rich antioxidant capacity actively neutralizes free radicals, thereby mitigating signs of premature aging. Furthermore, research suggests potential anti-inflammatory, photoprotective, and immunomodulating properties. It is also believed to help reduce surface lipids and stimulate collagen and elastin production, contributing to anti-wrinkle efficacy.

Key findings
- 01 In vitro studies at 0.5% concentration demonstrated significant antioxidant activity from polyphenol-polysaccharide complexes, including DPPH radical scavenging (63.58%-66.24%), hydroxyl radical scavenging (55.49%-62.24%), and superoxide anion scavenging (98.48%-99.52%).
- 02 Hot water extracts from fermented Hizikia fusiformis exhibited antioxidative, immunostimulating, and antihypertensive activities, with DPPH radical scavenging activity ranging from 13.83% to 62.15%.
- 03 Hizikia fusiformis fractions successfully improved atopic dermatitis indices in anti-CD3-stimulated splenocytes and 2,4-dinitrochlorobenzene-treated BALB/c mice, indicating anti-inflammatory potential.
- 04 Hot water soluble extract of edible hijiki demonstrated significant immunomodulating activity when administered to mice.

The Formula
Formulation
Stability
The optimal pH range for stability in cosmetic formulations is currently unknown. However, an aqueous extraction method for removing inorganic arsenic from Hizikia fusiformis found optimal conditions at pH 4 and 50°C, which may inform stability considerations.
Safety
Safety Profile
Formal safety assessments by regulatory bodies such as CIR, SCCS, or FDA for the topical use of Hizikia fusiformis water are not readily available. Concerns regarding high inorganic arsenic content are primarily related to the ingestion of the whole seaweed (Hijiki) and are not typically associated with purified cosmetic extracts, especially when proper processing methods are employed to remove contaminants. A 'Hizikia fusiformis callus culture extract' has no identified hazards according to GHS classification for cosmetic uses like antioxidants, hair conditioning, and skin conditioning, suggesting a low risk profile for water-based extracts, distinguishing it from potential risks associated with functional oils.
