Everything you need to know about Antarcticine.
Derived from a bacterium found in the icy waters of Antarctica, Antarcticine is a biotechnological active ingredient with exceptional properties: it protects the skin from the rigors of the cold, regenerates it, and preserves its hydration over the long term.
What is Antarcticine?
Antarcticine is a glycoprotein derived from biotechnology, isolated from a bacterial strain that thrives in the icy waters of the Antarctic. To survive in some of the most extreme conditions on the planet—intense cold, freezing temperatures, and desiccation—this microorganism has developed an extraordinary protective molecule. It is this survival capacity that cosmetics now put to work for your skin.
At Pure Altitude, this active ingredient resonates naturally with our philosophy: drawing exceptional ingredients from high-mountain environments and extreme conditions that are capable of strengthening the skin against daily aggressions.

How does Antarcticine protect the skin from the cold?
The strength of Antarcticine lies in its cryoprotective properties. Because it allows the bacteria from which it is derived to resist freezing, it helps the skin defend itself against the drying effects of cold, wind, and sudden temperature variations. It forms a true barrier of comfort that limits water loss and preserves the suppleness of the epidermis, even when climatic conditions become harsh.
It is a precious ally for all skin exposed to the mountains, skiing, or harsh winters, restoring softness and protection to skin that was previously distressed.
The benefits of Antarcticine for the skin
Beyond its protection against the cold, Antarcticine is a comprehensive active ingredient that acts on several fronts to revitalize the skin:
- Intense hydration: it retains water at the heart of the epidermis and helps restore its natural balance for plump, comfortable skin.
- Soothing action: it comforts skin sensitized by external aggressions and reduces feelings of discomfort.
- Anti-aging effect: by stimulating the production of collagen and elastin, it helps improve the elasticity and firmness of the skin while reducing the visible signs of aging.
- Repair: its regenerating properties help repair weakened skin, leaving it soft, smooth, and revitalized.
Advice from the Ferme de Beauté
In winter or at high altitude, apply your Antarcticine skincare product to clean, still slightly damp skin, morning and night. This simple step locks in hydration and strengthens the skin's protective film before exposure to the cold.
