What is it?

Fucus Vesiculosus Extract (INCI: Fucus Vesiculosus Extract) — extract of the brown seaweed Fucus vesiculosus (Phaeophyceae). Key components: fucoidan (sulfated polysaccharide from L-fucose, ~5-20% dry weight) — a powerful antioxidant and moisturizer; alginates — gel formation and hydration; florotannins (unique polyphenols from brown algae) — antioxidant and anti-aging effects; iodine and minerals (magnesium, potassium, zinc) — support for skin metabolism. Mechanism: fucoidan inhibits elastase and collagenase (anti-aging protection of the matrix); florotannins — direct quenching of free radicals and inhibition of tyrosinase (lightening effect).

Anti-aging products and spa cosmetics, moisturizers, products for mature and tired skin, thalassotherapy masks and wraps.

Key Benefits

✦
Fucoidan — inhibition of elastase and collagenase
Fucoidan, the main active polysaccharide of Fucus vesiculosus, demonstrates pronounced anti-aging activity through enzymatic inhibition. Mechanism: fucoidan binds to elastase (an enzyme that breaks down elastin fibers) and collagenase (MMP that breaks down collagen) → inhibition of their activity → protection of structural proteins in the dermis from degradation. Clinical data: fucoidan-containing extracts show significant reduction in the activity of these enzymes in vitro (40-60% inhibition at typical cosmetic concentrations). Result: preservation of the density and elasticity of the dermal matrix, prevention of premature aging.
◈
Hydration and strengthening of the barrier with marine polysaccharides
Alginates and fucoidan from Fucus vesiculosus provide a powerful moisturizing effect through gel formation and hydrophilic properties. Mechanism: polysaccharide chains bind significant amounts of water → formation of a hydrogel film on the skin surface → reduction of TEWL. Mineral complex (magnesium, zinc, iodine): support for normal cellular metabolism, cofactors for antioxidant defense enzymes (SOD with zinc). Thalassotherapy tradition: seaweed — a classic spa ingredient for remineralization and deep hydration of depleted skin.
✧
Florotannins — antioxidant and lightening effect
Florotannins — unique polyphenols found exclusively in brown algae, with powerful antioxidant and mild depigmenting activity. Antioxidant mechanism: direct quenching of ROS, surpassing the activity of some traditional antioxidants (vitamin E) in comparative studies. Depigmenting action: partial inhibition of tyrosinase → gentle evening of skin tone, prevention of hyperpigmentation. Anti-aging synergy: antioxidant protection + enzymatic inhibition (fucoidan) + hydration (alginates) = comprehensive spa effect for mature, tired, and dull skin.
