The Biocellulose Mask: the express anti-thirst treatment for your routine
Discover the skincare ritual that has won over French women: the Pure Altitude organic cotton sheet mask. In just 15 minutes, it infuses the skin with a concentrate of mountain plants for intense hydration, leaving the complexion fresh and luminous. A closer look at your routine essential.
From sheet mask to biocellulose mask
Born in Asian beauty rituals, the sheet mask has become the express hydration step of every skincare routine. Pure Altitude adopted it as early as winter 2019 with its organic cotton sheet mask. Today the brand goes further with the Biocellulose Hydration & Radiance Mask: an ultra-thin natural veil soaked in an intensely hydrating serum made with 99% ingredients of natural origin.

Biocellulose, a second skin
Biocellulose is a natural material that hugs the contours of the face like a second skin. It holds a large amount of serum against the skin and releases it gradually throughout the application. The result: the active ingredients work longer and more effectively than with a classic fabric mask.
An anti-thirst serum with mountain plants
- A hydrating complex that keeps water at the heart of the skin and restores suppleness and comfort.
- 7 alpine plants to even out the complexion and reveal the skin's natural radiance: cowslip, lady's mantle and speedwell (antioxidant), mallow and lemon balm (softening and soothing), yarrow (skin comfort) and peppermint (freshness).
- Edelweiss, emblem flower of the Alps and Pure Altitude's signature ingredient, which helps protect the skin from oxidative stress.
How to use the biocellulose mask?
- Remove the two protective films.
- Apply the mask to clean, dry skin, smoothing it with your fingertips.
- Leave on for 15 minutes while the biocellulose releases the serum.
- Remove the mask and massage the remaining serum into the skin, down to the neck. Do not rinse.
The Ferme de Beauté tip: for a spectacular refreshing boost after skiing or sun exposure, place the mask in the fridge for about ten minutes before applying it. Its minty freshness will feel even better.

When to use it and what results to expect?
The biocellulose mask suits all skin types, especially dehydrated skin, dull complexions and skin exposed to cold, wind and sun. In 15 minutes, the skin is quenched, fresh, supple and luminous. Treat yourself to this ritual once or twice a week, before an evening out, after a day on the slopes or a long journey.
Extend the ritual: your hydration routine
After the mask, apply the Hydra Antarctica Serum, concentrated in antarcticine and hyaluronic acid, then seal in hydration with the Edelweiss Cream N°1, which protects the skin from external aggressions. A Pure Altitude trio for skin that stays fresh and luminous.
