Extract of Channelled wrack

Brown algae

Pelvetia algae is rich in polysaccharides and fucose, providing moisturising, anti-ageing and regenerating properties.

Composition

According to the bibliographic records: Pelvetia canaliculata (%)
Fucose 72 | Uronic acids 28.1 | Vitamin B9 0.3

Exploitation

The algae is harvested by the company BioMolenez. Harvesting is done by hand at the highest level of the foreshore, starting in late spring.

Once harvested, the seaweed is macerated and filtered to obtain an extract containing a maximum of bioactive compounds. Pelvetia can be recognised by its bushy, channel- or gutter-shaped thallus. It lives attached to rocks. Its colour varies between olive green and black when dry.

Mainly found in the cold coastal waters of the North Atlantic, especially in the coastal regions of North America (such as Canada and the United States) and Europe (such as the UK, France, Spain and Norway). It is often found on rocks and stones, in areas exposed to waves and strong currents. It is also found in the coastal waters of Antarctica.

Temperature tolerance: 1 to 15

Cosmetic properties

Moisturizing

The uronic acids that make up the GAGs (Hydration test - corneometry) retain water on the surface of the skin for an immediate film-forming effect.

Regenerating

Fucose and vitamin B9 promote cell proliferation. A study has shown that the presence of fucose in algae (1 ug/mL) promotes cell proliferation by up to +19%

Antioxidant

Fucose inhibits elastases* in order to preserve the skin's elasticity and acts on wrinkle filling thanks to collagen synthesis. The same study showed that the presence of fucose in the algae (10 ug/mL) inhibited about 50% of elastases.
