Science
Mechanism of Action
Fucose strengthens the skin barrier by acting as a crucial component of glycoproteins and glycolipids, which serve as intercellular 'glue,' optimizing moisture retention and bolstering skin resilience. It actively stimulates fibroblasts, promoting the increased production of collagen and elastin to firm the skin and diminish the appearance of wrinkles. Functioning as an antioxidant, Fucose neutralizes free radicals, thereby mitigating premature aging. Furthermore, it inhibits tyrosinase, an enzyme involved in melanin synthesis, contributing to skin brightening and a reduction in hyperpigmentation. Fucose also provides protective, healing, and immunostimulant properties, essential for cellular communication and immune response, and helps alleviate symptoms of allergic contact dermatitis while improving overall skin texture.

Key findings
- 01 Clinical data indicates that Fucose at concentrations of 0.1-1% (w/v) acts as an effective anti-aging, skin moisturizing, and conditioning agent.
- 02 L-fucose-containing preparations have been observed to increase skin thickness and densify collagen bundles, effectively decelerating skin aging processes.
- 03 A fucose-rich polysaccharide preparation significantly improved skin surface relief by an average of 37.16% (with up to 50% improvement) and reversed age-dependent skin alterations in 20 female volunteers after 4 weeks of treatment.
- 04 Applied twice daily for 4 weeks, a fucose-rich polysaccharide in a base-cream led to a significant improvement in periorbital wrinkles for 65% of 20 voluntary women, with some achieving up to 100% improvement.
- 05 A 0.1% concentration of bacterial fucose-rich polysaccharide (Fucogel®) significantly reduced substance P release in an in vitro stinging test, demonstrating notable soothing properties.

The Formula
Formulation
Stability
Fucose exhibits high stability and is readily soluble in water (up to 50 g/L or 50 mg/mL), as well as in alcohol, methanol, ethanol, DMSO, and dimethyl formamide. While no specific optimal pH range for Fucose stability was identified, general cosmetic formulations typically maintain a pH between 4 and 6 for ingredient efficacy and skin health.

Safety
Safety Profile
The CIR Expert Panel concluded Fucose and related saccharides are 'safe as used in cosmetics.' It is also a common dietary sugar with well-established oral safety. No specific SCCS opinion was found, and while the FDA does not pre-approve cosmetic ingredients, fucoidan concentrate (containing Fucose) holds GRAS status for food use.
