The diverse world of seaweeds is an invaluable source for the discovery of new chemical compounds.

Our research helps to describe new properties of algae every day. We study this unique diversity, are inspired from it and develop innovations that make a responsible use of this natural ressource.

Another goal in the identification of these molecules is to gain better understanding of the ecology of marine life.  We choose our research projects based on environmental observations.

Red algae (Gelidium sesquipedale), the source of our active principle Alga-gorria®, is replete with a number of natural mechanisms for prevention and protection

  • Powerful antioxidant molecules (including carotenoids and flavonoids),
  • Oligo-elements,
  • Mineral salts,
  • Essential amino-acids.

Thanks to our specific extraction technology, we are able to maximise the preservation of the protective powers of this red seaweed. Sea water, used in the extraction, provides natural elements that improve the protective powers of each product.

Alga-gorria® prevents skin damage thanks to a unique active principle that supports the cellular defence systems and slows down the ageing process.

Alga gorria is an extract of the red seaweed Gelidium sesquipedale, from the coast of the Basque Country. This patented extract (FR2978915) is made up of an association between carotenoids (lutein and zeaxanthin) and mycosporine like amino acids that confer a wide spectrum of neutralisation of free radicals and glycation end products.

The extraction technology used was developed with respect to the environment and does not implicate dangerous organic solvents. The extraction process is carried out with sea water, in which the minerals and pH act to enhance yields of the active molecules and to stabilize the extract through its conserving properties. At skin level, sea water promotes osmotic exchanges, hydrates and enables a better diffusion of the active components.

At concentration of use, Alga-gorria inhibits almost 40% of in vitro glycation reactions.
Alga-gorria is up to 5 times more antioxidant than pure vitamin C. Synergy between antioxidant molecules confers a large antioxidant spectra.

Oxidative stress

Free radicals are reactive and dangerous fragments of molecules that affect through oxidation all cellular components: DNA; structural proteins, membrane enzymes and lipids. These alterations are a cumulative part of cellular aging.

If free radicals are being produced continually, numerous factors influence and enhance their production:

At skin level, these factors can be environmental stress like pollution, or UV; but also parameters that vary according to the individual such as nutrition, stress or physical fitness. The phenomenon is called “oxidative stress”.

“Antioxidant” denotes any agent that delays, stops or prevents oxidative damage that can happen in our skin cells.

Glycation

Glycation is a part of skin aging in the same way that oxidation effects are. Simply put it is the spontaneous modification of proteins by sugars. The structural proteins of the dermis are particularly affected by this phenomena, especially collagens, whose elasticity is considerably reduced by glycation.

The appearance of glycated proteins in the skin is observed for the age of 20 and it is estimated that glycation end products accumulate at a rate of 3.7% per year. Their occurrence is also potentiated by UV exposure.

As well as affecting the physicochemical properties of the altered molecules, glycation also diminishes cellular proliferation, promotes cellular senescence, favours free radical formation, and stimulates inflammation.
