Shaped by human hands, the Guérande salt marshes have inspired a range of innovative and certified organic cosmetic treatments that draws its active ingredients
in the natural resources of this extraordinary ecosystem.

The idea was born six years ago

Convinced by the exceptional richness of this ecosystem, the Les Salines de Guérande Cooperative requests a marine cosmetology laboratory which intervenes to study the natural environment, identify resources and develop their potential.

Eaux-Mères, algae, halophyte plants and clays are carefully sampled and studied with the aim of integrating the formulation of a new range of natural cosmetic treatments formulated for all skin types.

The treasures of the salt marshes are exceptionally rich in essential minerals and trace elements (sodium, calcium, magnesium, potassium, phosphorus, zinc, iron, iodine, etc.). From these natural resources, the fundamental active principles of Guérande cosmetics are extracted: the Mother Waters collected in the last evaporation ponds are loaded with active ions, algae and halophyte plants have remarkable hydra-regulatory, antioxidant and restructuring properties. , salts and clays are remineralizing and purifying.

A new agrobiological sector was born, designed for the preservation of the environment, in a sustainable, ethical and responsible approach, managed with absolute respect for the natural environment, its resources and the work of salt workers. Expert in organic and natural cosmetics for over 45 years, the Science & Nature Laboratory, located 1 hour from Nantes, is responsible for the industrial and logistical implementation of this new range of ecological and organic care certified by Ecocert Greenlife.

HYDRA Guérande range: two new high-hydration and antipollution facial treatments

Last November, the 2 new products HYDRA-aqua and HYDRA-nuit announced the launch of the HYDRA range from GUÉRANDE, completed today by HYDRA-care and HYDRA-comfort, two new anti-pollution “high hydration” facial treatments in two textures, light and rich, adapted to each type of skin: normal to combination or prone to dryness.

It is because the presence of water in the skin reflects the light well and makes it beautiful that hydration remains THE basis and concerns all skin types. A moisturizer provides assimilable water, agents that capture water in the skin and a film that protects it from its evaporation.

HYDRA-care and HYDRA-comfort meet the essential needs of thirsty skin.

Stimulate and maintain its hydration level to avoid the discomfort of tightness and premature skin aging. Quenched, the skin regains more suppleness and regains radiance.

HYDRA assets:

Eaux-Mères, the flagship active ingredient in Guérande cosmetics, provide all the mineral wealth distilled by the salt marshes. In affinity with the natural balance of cells, they offer the skin comfort, energy and vitality and provide it with their restorative and soothing properties *.

The macro-alga Enteromorpha, rich in natural antioxidants (polyphenols) and fructo-oligosaccharides known to help the skin to maintain its hydration, protects from free radicals and dehydration.

Green Salicornia promotes the maintenance of hydration through its content of amino acids, the main constituent of NMF (Natural Hydration Factors).

It is also rich in Vitamin A, recognized for its benefits on skin health.
Two complementary active ingredients reinforce the hydrating power of the formulas: sodium from Pca with hygroscopic power which captures water molecules and a polysaccharide resulting from biofermentation which protects against dehydration and soothes. Finally, brown seaweed extract, a “second skin” active ingredient protects the epidermis from external aggressions and captures pollution particles, for an even brighter complexion.
