Everything you need to know about Antarcticine.
Derived from a bacterium found in the icy waters of the Antarctic, Antarcticine is a biotech active ingredient with exceptional properties: it protects the skin from the harshness of the cold, regenerates it and keeps it lastingly hydrated.
What is Antarcticine?
Antarcticine is a glycoprotein born of biotechnology, isolated from a bacterial strain that thrives in the icy waters of the Antarctic. To survive some of the most extreme conditions on the planet – intense cold, frost and desiccation – this micro-organism has developed an extraordinary protective molecule. It is this capacity for survival that skincare now puts to work for your skin.
At Pure Altitude, this active ingredient resonates naturally with our philosophy: drawing exceptional ingredients from high mountains and extreme environments, able to strengthen the skin against everyday aggressors.

How does Antarcticine protect the skin from the cold?
Antarcticine's strength lies in its cryoprotective properties. Just as it allows the bacterium it comes from to withstand freezing, it helps the skin defend itself against the drying effects of cold, wind and sudden changes in temperature. It forms a true barrier of comfort that limits water loss and preserves the skin's suppleness, even as the weather turns harsh.
It is a precious ally for all skin exposed to the mountains, skiing or bitter winters, restoring softness and protection where the skin had been put to the test.
The benefits of Antarcticine for the skin
Beyond protecting against the cold, Antarcticine is a complete active ingredient that works on several fronts to revitalise the skin:
- Intense hydration: it holds water deep within the epidermis and helps restore its natural balance, for plumped, comfortable skin.
- Soothing action: it comforts skin sensitised by external aggressors and eases feelings of discomfort.
- Anti-ageing effect: by stimulating the production of collagen and elastin, it helps improve the skin's elasticity and firmness while softening the visible signs of time.
- Repair: its regenerating properties help repair weakened skin, leaving it soft, smooth and revitalised.
The Ferme de Beauté's tip
In winter or at altitude, apply your Antarcticine skincare to clean, still slightly damp skin. This simple gesture locks in hydration and reinforces the skin's protective film before you face the cold.
