Nearly 30,000 species of algae have been recorded in the world. These thousand-year-old marine plants which have chlorophyll, are considered as plants, but the seaweed does not have roots since it does not need them to feed.
The cells of the algae contain many chloroplasts which contain this green pigment, chlorophyll, capable of capturing light energy and converting it as a source of energy by the process of photosynthesis.

Thanks to the light energy, water (H2O) and carbon dioxide (CO2) absorbed by the algae are converted into carbohydrates (C6 H12 O6) and oxygen (O2).
This is probably the most important biochemical process in the living world as oxygen molecules released into the atmosphere continuously enrich the air for the benefit of mankind.

Predominantly composed of water, 90% of their weight, the algae are rich in polysaccharides, which allows them to stay hydrated. They are also made of mineral salts, vitamins and proteins of high nutritional quality containing mostly the essential amino acids.

Algae take very varied shapes and sizes, from microscopic to that which can reach tens of meters in length. All possessing chlorophyll pigments, their differences in color are explained by the presence of other pigments which  mask the green of the chlorophylls.

They are found in the marine environment as well as in fresh water, at the shorefront, on the surface or in the depths of the ocean. Other algae will also develop in non-aquatic environments (soil surfaces, tree trunks, walls, rocks), in this case they are called terrestrial or aerial algae.

Plunged in a hostile environment: stresses of tides and winds, thermal stress, salt shocks, UV aggressions, pollution, bacterial attacks, algae have had to adapt and develop resistance in order to survive, as no other terrestrial plant would have to do it.

It is at the heart of this bio similarity with the human organism that the algae offer us their active ingredients. NUAJ, for its part, draws its marine resources to north of Brittany, in the archipelago of Brehat, the third richest marine flora in the world.


These are algae of large size, even giant-sized and whose vegetative system is visible to the naked eye.
There are more than 13,000 species in the world, only fifty of which are used in the world of cosmetics.
Located mainly on the coasts, they cover most of the aquatic and shallow fields since they require light for photosynthesis. They develop mainly in the tidal zones, that is to say the part of the coastline above the water at low tide and below it at high tide.
Rich in water, polysaccharides, sulphated and antimicrobial ingredients, they have the ability to filter water and concentrate its elements.
The brown algae are known as laminaria digitata, they are generally very large and rich in hydrocolloids, polyphenols, iodine and pigments.
Green algae are rather small and thin and live near the surface of the fresh water. They are rich in minerals, polysaccharides and chlorophyll a.
As for the red algae, they are particularly rich in phycocolloids, carotenoids and B vitamins.


They are increasingly being studied, and today we estimate the existence of 200,000 to 1 million species. More commonly known as phytoplankton, only a few of them are used.

Marine plants

Let us not forget this plant group. As a terrestrial plant, the marine plant has roots, stems, leaves and even flowers but contains fewer aromatic molecules than a terrestrial plant. Living on salty terrain, it has the ability to survive in extreme conditions.


Its main property is to reduce dark circles. Dark circles are created because of small veins under the eyes that, when they dilate, create a poor circulation of blood. The skin under the eyes is very fine and with the addition of stress, lack of sleep and pollution, dark circles appear easily.
This agent is an extract of the green micro algae “Chlorella vulgaris” which is rich in amino acids and oligo peptides. The use of this active allows to tone and firm the skin but also to clarify and lower its pigmentation, which helps to reduce dark circles.
You can find this active ingredient in the Algae Benefit range “Robe Satinée”.


These brown algae living in extreme conditions (exposure to waves, lack of light …) is present at NUAJ in two different active ingredients:

In the first one, it will plays the role of anti-aging agent which moisturizes and firms at the same time the skin. It acts on the elasticity and increases the firmness of the skin. Its rich and balanced composition improves skin nutrition, its protection and suppleness while moisturizing and plumping.
You can find this active ingredient in the eye contour care “Robe Satinée” and the day cream gel ”Éclat de Grâce” of the Algae Benefit range.

This second one, also anti-aging, will act against the premature skin aging by targeting the production of progerin, the major protein responsible for aging. This skin protector will reverse the effects of age giving elasticity, firmness and reduction in wrinkles depth.
You can find this active ingredient in the “Jouvencelle” serum of the Algae Benefit range.


Pollution is a global concern. The skin is the interface between our body and the environment, and is put to test every day (urban dust, ozone, micro-particles, heavy metals, …). All these factors cause skin damage, leading to skin dysfunction, premature aging, sebum excess and weakening of the skin barrier.
This active ingredient derived from an innovative cell culture technology will purify the skin in order to fight the effects of pollution against the skin. The excretion of sebum is regulated, the skin is visibly less oily in a polluted atmosphere.

You can find this active ingredient in the day cream ” Éclat de Grâce” of the Algae Benefit range.


Criste marine or sea fennel is a rare marine plant that is found on the salty soils of the Brittany coast. Regularly exposed to the waves, it has the peculiarity of being able to live on rocks. A terrestrial plant could not withstand such conditions. Its extreme resistance is what our skin needs to survive urban life.

The active ingredients extracted from it fight pollution and the aging by restoring the cellular renewal and the radiance of the complexion. Brighter and more homogeneous, less dull and greyish, the skin is sublimated.

You can find this active ingredient in the night cream ” Lueur Nivéenne” of the range Algae Benefit.


Derived from a sweet combination, this active hydraconcept’s main purpose is the hydration of the skin. It will boost all the actors of hydration (lipids, proteins, polysaccharides) and allow the restructuring of the skin barrier. Soft and smooth, the skin is visibly more beautiful.

Find this active ingredient in the eye care ” Robe Satinée”, the night cream ” Lueur Nivéenne ” and the serum “Jouvencelle” of the range Algae Benefit.


Combination of a fatty acid, palmitic acid and an amino acid, glycine, this strong active anti-wrinkle ingredient will target the key markers of aging. It will act against the consequences of inflammation and stress on the skin, smoothing the wrinkles and increasing the firmness and tone of the skin. This molecule will also have effects on the radiance of the complexion that will be illuminated and rejuvenated.

You can find this active ingredient in in the day cream ” Éclat de Grâce” of the Algae Benefit range.


An appearance of zero defect and a unified complexion are also key points of the anti-aging skin strategy.
This active ingredient extracts stem cells from pomegranate seeds, a fruit known for its exceptional antioxidant powers. It will unify the complexion and improve its aspect. Thanks to this clearness indicator and radiance perfector, the skin is visibly smoother and radiant.
