Exploitation
The genus Fucus is harvested by the company BioMolenez. This brown seaweed grows in the middle of the foreshore, on either side of the mid-tide, on sheltered sites, mixed with Ascophyllum nodosum. It is very present around the island of Molène and is harvested with a sickle or knife.
Once harvested, the seaweed is macerated and filtered to obtain an extract containing a maximum of bioactive compounds.
Mainly found in the coastal waters of the North Atlantic and the Baltic Sea. It is less common in the coastal waters of the Mediterranean Sea.
Temperature tolerance: 3-25
Cosmetic properties
Firming
The fibres and alginic acid help to firm and maintain the elasticity of the skin, for a tightening and firming effect.
Antioxidant
Fucoidanes have a strong antioxidant power to reduce oxidative stress.
Remineralizing
Its high mineral and oligoelements content provides the fundamental nutrients for a vital skin.
Moisturizing
The high alginate content helps retain water on the surface of the skin while the calcium facilitates the synthesis of lipids that promote hydration
