“I loved the texture. At first I thought it would foam, but no, it tightens the skin and afterwards leaves it beautifully radiant — a top-quality serum, really a good product.”

A few drops. Three actions. A synergy of marine actives smooths features, plumps the skin and firms the face.
Breton marine active ingredients, made in France
Our marine active ingredients come from the island of Molène, in Brittany. Waters renowned for their biodiversity and quality.
Biophotonic violet glass
Miron violet glass protects the formula from light. It preserves its freshness over time. The bottle is reusable and recyclable.
A Home Compost certified carton
The first Home Compost-certified carton in France. Packaging designed to return to nature after use.
Élixir Visage N°1 is for skin that is starting to lose its elasticity, hydration, or firmness, as well as for skin that already has fine lines and wrinkles.
It is particularly suitable if you are looking for:
visibly smoother skin;
an immediate tightening effect;
more bounce;
comfortable hydration without a greasy finish;
targeted action on the first signs of ageing;
an anti-ageing skincare product inspired by marine active ingredients.
Élixir Visage N°1 was formulated to meet three essential needs:
hydration,
visible smoothing,
soothing feelings of discomfort.
Effectiveness depends on regularity of use, skin type, complete routine, and lifestyle. A one-time application can also give a fresh and smoothing effect.
Apply a few drops onto clean skin, morning and/or evening. Gently massage into the face, focusing on fine lines and wrinkles, until absorbed.
Follow with your moisturiser for added comfort.

Our seawater comes from the Iroise Marine Natural Park, a protected marine area off the coast of Brittany. These waters are renowned for their quality and richness. Our seawater naturally concentrates essential minerals and trace elements, in proportions close to those of the skin. Microfiltration preserves its purity and mineral balance. In cosmetics, it is used for its remineralising and rebalancing properties.

Hyaluronic acid is a molecule naturally present in the skin, where it retains water within the extracellular matrix — up to 1000 times its weight in water. It is one of the most widely used humectants in cosmetics, and an ingredient increasingly found in food supplements, often in the form of sodium hyaluronate.
Molecular weight changes how it works: high-molecular-weight HA forms a hydrating film on the surface and smooths the skin instantly; low-molecular-weight HA penetrates more deeply, where it acts on elasticity and the skin barrier. This is why cosmetic formulas often combine several molecular weights.

On rocky seabeds swept by Atlantic currents grows a brown seaweed shaped like a small broom, able to survive conditions that few marine species can tolerate.
It is this resilience that caught the attention of laboratories: in culture, in contact with skin fibroblasts, this seaweed extract stimulates the synthesis of type I collagen by 61% — the protein that structures and supports the dermis. The active is COSMOS Organic certified and Ecocert approved.

Fucus (Fucus vesiculosus) is a brown seaweed that grows on the rocky coasts of the North Atlantic, between the tides. Ours is organic, harvested in the waters of the Iroise Sea, around the island of Molène.
This seaweed concentrates three families of compounds prized in marine cosmetics: polysaccharides — fucoidan, alginates —, phlorotannins, antioxidant polyphenols specific to brown seaweeds, and minerals and trace elements.
In cosmetics, its extracts are known for protecting the skin from oxidative stress, strengthening the hydrolipidic film and providing a toning effect, for more comfortable, smoother-looking skin.

Aloe vera is a succulent plant whose gel has been used for centuries to hydrate and soothe the skin. It is rich in polysaccharides — including acemannan — minerals and amino acids.
On the skin, it forms a light, non-occlusive veil: it helps reduce feelings of heat and tightness while supporting the skin barrier's natural repair mechanisms. The result: suppler skin that looks comforted and more radiant.
In your evening routine, after sun exposure, after shaving or on reactive skin — for instant freshness and lasting comfort.

Fucogel® is a biomimetic active ingredient obtained through plant fermentation, designed to hydrate the skin instantly and lastingly. It forms a non-occlusive protective film on the surface that smooths skin texture and provides an instant feeling of comfort.
By strengthening cell cohesion and the skin's barrier function, it helps limit dehydration and feelings of discomfort. It also improves the texture of the formulas it is added to.
What sets it apart: hydration that lasts up to 8 hours after application.

The complete routine
The answers to your questions
The serum offers a light texture concentrated in active ingredients. The cream completes the routine by providing extra comfort and helping to limit water loss.
The serum prepares the skin; the cream finishes the routine.
Yes, on the eye contour where fine lines are visible. Apply a small amount, avoiding direct contact with the eyes.
No. It can be used as soon as the first signs of ageing appear, and also when wrinkles and fine lines are already visible.
Morning, evening… or both!
Adapt the Élixir to your routine and your skin's needs. A few drops on clean skin, before your cream, are all you need.
Élixir Visage N°1 is based on precise cosmetic mechanisms: hydration, skin comfort, surface film, and visible smoothing effect. Its formula combines several ingredients capable of acting on the skin's surface, without promising a medical transformation.
Hyaluronic acid helps retain water and improves the appearance of the superficial layers of the epidermis. It contributes to visibly more supple, smoother skin, with fewer dehydration fine lines.
Natural biopolymers from red algae and plants form a thin film on the skin. This film can create an immediate tightening effect and give a clearer, fresher, and smoother appearance.
Aloe vera and polysaccharides contribute to skin comfort. They help reduce feelings of tightness and improve the perceived softness of the skin.
