Science

Mechanism of Action

This extract contains bioactive compounds, primarily phlorotannins and other polysaccharides, which underpin its diverse skin benefits. It functions as a powerful antioxidant by neutralizing free radicals and mitigating oxidative stress, key drivers of skin aging. Fucus Spiralis Extract exhibits anti-inflammatory effects to calm irritated skin and provides anti-enzymatic action by inhibiting collagenase, elastase, and hyaluronidase, thereby preserving the skin's extracellular matrix for improved elasticity and firmness. Additionally, it offers photoprotection by reducing reactive oxygen species (ROS) induced by H2O2 and UVB, supports a balanced skin microbiome, enhances hydration, and helps regulate sebum production.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Unknown

Fucus Spiralis Extract has been included in a CIR safety assessment of brown algae-derived ingredients, concluding that the majority are safe for cosmetic use under current practices. While specific maximum safe concentrations for Fucus Spiralis Extract itself are not explicitly stated, in vitro cytotoxicity studies showed some fractions were cytotoxic at 1000 µg/mL but non-toxic at 600 µg/mL. A related extract, Fucus vesiculosus, has been noted for low irritation risk but potential slight comedogenicity, suggesting patch tests for sensitive or oily skin may be prudent for broader brown algae usage.
