HIZIKIA FUSIFORME EXTRACT.

Valuable CAS - / SKIN CONDITIONING

Hizikia Fusiforme Extract is a multi-functional marine ingredient, celebrated for its hydrating and conditioning properties that promote soft, smooth, and plump skin. Rich in potent antioxidants and essential minerals, it offers significant anti-aging, photoprotective, and brightening benefits by combating free radicals, enhancing collagen, and inhibiting melanin synthesis.

Science

Mechanism of Action

This extract functions as a comprehensive skin conditioner, forming a subtle barrier to lock in essential moisture, thereby enhancing skin plumpness and radiance. Its rich composition of vitamins, minerals, and potent antioxidants actively neutralizes free radicals, mitigating premature aging and fortifying the skin's defense against environmental aggressors. Specific components like fucoidan (102.67 kDa) demonstrate robust antioxidant activity by reducing intracellular reactive oxygen species, and provide photoprotection by inhibiting collagenase and MMPs while promoting collagen synthesis. Furthermore, it actively suppresses melanin production by down-regulating the microphthalmia-associated transcription factor (MITF) via the ERK-MAPK pathway, consequently reducing tyrosinase and tyrosinase-related proteins (TRP-1 and TRP-2). It also exhibits anti-inflammatory properties and supports cellular renewal.

Key findings

  1. 01 An in vitro study utilizing a 20% ethanol extract demonstrated enhanced cell survival following oxidative stress (H2O2 treatment) and stimulated the production of anabolic factors crucial for skin structure, including collagen types I and II, and aggrecan.
  2. 02 Isolated fucoidan from Hizikia fusiforme exhibited potent antioxidant activity, significantly reducing intracellular reactive oxygen species. It also improved the viability and reduced apoptosis in human keratinocytes exposed to UVB radiation, alongside inhibiting melanin synthesis in α-MSH-stimulated B16F10 melanoma cells.
  3. 03 In vivo research on D-galactose-induced aging mice revealed that polyphenol-polysaccharide complexes derived from Hizikia fusiforme possessed high antioxidant capabilities and conferred anti-aging effects. This was mediated by modulating antioxidant enzymes, reducing lipid peroxidation, and upregulating Nrf2 pathway components.

Stability

Specific optimal pH ranges for cosmetic formulation stability are not extensively documented. However, the solubility of Hizikia Fusiforme Extract can vary based on extraction methods; water-based extractions typically yield water-soluble polysaccharide complexes, while functional oils derived from it are oil-soluble.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Unknown

Formal safety assessments by CIR, SCCS, or FDA for cosmetic use are not readily available. Hizikia fusiforme naturally contains arsenic compounds (inorganic and organic). While generally uncommon, side effects are possible, and a patch test is recommended before widespread use. Some components of Hizikia fusiforme functional oil (HFFO) were predicted to pose a skin sensitization risk, which requires further validation.
